-!!1. Introduction
-
-
-Many people use Linux to burn CD-ROMs, because it is reliable
-and easy. No bluescreens while burning and no headaches about
-getting the right combination of hard- and software. It just
-works once properly set up. The CD-writing HOWTO explains the
-setup, how to put data on the media and gives some interesting
-applications kindly submitted by the readers.

-!!1.3 Suggested readings
-
-
-
-
-
-
-You may need the handbook for your Linux-distribution to learn about
-installing a new kernel. I'm really clueless about this issue when
-it comes to any other Linux distribution than my own.
-
-
-The
-CD-R FAQ
-is a general FAQ about compact-disk recordables (CD-R), CD-writers and
-the required software.
-As most CD-writers can be used to read CD-ROMs, too, you may want to read
-the ''Linux CD-ROM HOWTO'', the ''Linux SCSI
-HOWTO'' and the ''Linux Kernel HOWTO''.
-
-
-
-
-
-
-
-!!1.4 Terminology ... lasers at maximum ... fire!
-
-
-
-
-
-
-''CD-ROM'' stands for ''Compact Disc Read Only Memory'', a
-storage medium utilizing an optical laser to sense microscopic pits on a
-colorful shimmering disk. The pits represent the bits of the information
-and are so petite that some billions of them fit on the
-disc. Thus a CD is a mass-storage medium.
-
-
-The term ''CD-R'' is a short form of ''CD-ROM recordable'' and
-refers to a CD that doesn't have those microscopic pits on its surface.
-Thus it is empty. The CD-R has a special chemical film inside into which
-pits can be burned. This is done by giving the laser which normally just
-senses the pits a little bit more power so it burns the pits. This action
-can only be taken __once__ on a CD-R. You can leave out some
-areas for later writing, creating a so called ''multi-session CD''.
-
-
-The ''CD-ROM rewritable'' (short: ''CD-RW'') was developed to
-work around the limitation of CD-R media. With a CD-RW burner the laser
-can do both, burn pits into the media and also melt the media back into
-its original state. This is possible, because the laser does not really
-burn holes into the media, which would get lost in a puff of smoke.
-A decent analogy for the technique is an ice-hockey game: by
-driving over the ice, a players (laser) leave scratches in
-it. The pattern in the ice (media) is a recording of what
-happened on the ice during one round. In between the periods
-of the game, the Zamboni cleaning car drives over the ice and
-fills the scratches by melting the very top layer of the ice.
-(Zamboni is ''the'' brand name for cleaning cars in
-ice-hockey stadiums). This way the pattern on the ice is
-cleared and a new round can begin. The scientific term for
-evaporating, condensing, melting and freezing is "phase
-change", thus the name "phase change devices" for
-CD-RW-writers.
-
-
-This HOWTO deals with the task of writing CD-Rs and CD-RWs. Welcome on board,
-captain.
-
-
-
-
-!Adaptor vs. Adapter
-
-
-The the most frequent spelling within the kernel sources is adapter
-(adapter: 4283, adaptor: 154). Even more important, the parameters of
-module options and aliases are naturally affected, like in
-"scsi_hostadapter". So in order to achieve a consistent spelling throughout
-configuration examples and document text, I follow that convention
-regardless of the correct spelling.
-
-
-
-
-
-
-
-!!1.5 Supported CD-writers
-
-
-
-USB CD-writers are currently not supported at all. Apart from that you can
-safely assume that most newer IDE/ATAPI- and SCSI-writers work under
-Linux. Newer drives are mostly MMC-compliant and are therefore supported. If
-the SCSI-version of a particular writer works, the IDE/ATAPI-version will
-most likely work and vice versa. However, some people want to get a warm
-and fuzzy feeling by reading the exact model of their writer in some sort
-of compatibility list. That is the reason why I didn't throw the following
-list out of the HOWTO.
-Here is a comprehensive summary of drives reported to work with cdrecord:

-''Table: CD-writers supported under Linux''
-
-
-
-
-
-
-The detailed list of models which have been reported to work or not to work
-under various Unix-like operating systems is available online from
-http://www.guug.de:8080/cgi-bin/winni/lsc-orig.pl.
-
-
-
-
-
-If your hardware isn't supported you can still use Linux to create an image
-of the CD. You may wish to do so because most burning software for DOS does
-not deal with !RockRidge-extensions (Unix-like filesystems on CD-ROM). In a
-second step, you can use DOS or Macintosh software to write the image to
-the CD-R.
-
-
-
-
-
-
-
-!!1.6 Supported "features"
-
-
-
-Two There are two classes of utilities: the hardware drivers
-and the data-formatters. The hardware drivers support the following
-features:
-
-
-
-
-
-Supported Feature cdwrite-2.1 cdrecord-1.6 cdrdao
-----------------------------------------------------------
-IDE/ATAPI yes yes yes
-Parallel Port no yes yes
-CD-RW no yes yes
-Audio CD yes yes yes
-Data CD-ROM yes yes partial
-Multisession partial yes no
-TAO (track at once) yes yes yes
-DAO (disk at once) no partial yes
-packet writing no no no
-
-''Table: ''
-
-
-
-cdwrite is unmaintained software referenced only for
-completeness. Please use cdrecord instead, as it
-supports a wider range of hardware and has significantly
-more features. The main benefit of cdrdao is the ability to create audio
-CDs without two seconds of silence between the tracks (writing
-in disk-at-once (DAO) mode).
-
-
-The tools classified as "data-formatters" organize the data
-on the media ("put a filesystem on it").
-
-
-
-
-
-Feature mkisofs mkhybrid mkvcdfs
--------------------------------------------------------
-ISO 9660 yes yes no
-!RockRidge yes yes no
-El Torito yes yes no
-HFS no yes no
-Joliet yes yes no
-Multisession yes yes no
-CD-Extra yes yes no
-Video-CD no no yes
-
-''Table: ''
-
-
-
-The most obvious difference between the ISO 9660 filesystem compared to the
-ReiserFS or Extended-2 filesystem is: you can't modify files once they are
-written. Other limitations of the ISO-9660-filesystem include:
-
-
-
-
-
-* only 8 levels of sub-directories allowed (counted from
-the top-level directory of the CD)
-*
-
-* maximum length for filenames: 32 characters
-*
-
-* 650 MB capacity
-*
-
-
-
-''!RockRidge'' is an extension to allow longer filenames and a deeper
-directory hierarchy for the ISO-9660 filesystem. When reading a CD-ROM with
-!RockRidge extensions under Linux, all the known properties of files like
-owner, group, permissions, symbolic links appear ("feels like a Unix
-filesystem"). These extensions are not available when reading the CD-ROM
-under DOS or the heterogenous Windows-family of operating systems.
-
-
-''El Torito'' can be used to produce bootable CD-ROMs. For this feature
-to work, the BIOS of your PC must support it. Roughly speaking, the
-first 1.44 (or 2.88 if supported) Mbytes of the CD-ROM contains a
-floppy-disk image supplied by you. This image
-is treated like a floppy by the BIOS and booted from. (As a consequence,
-while booting from this virtual floppy, your original drive A: (/dev/fd0)
-may not be accessible.)
-
-
-''HFS'' lets a Macintosh read the CD-ROM as if it were an HFS volume
-(the native filesystem for MacOS).
-
-
-''Joliet'' brings long filenames (among other things) to newer variants
-of Windows (95, 98, NT). However, the author knows of no tool that allows long
-filenames under plain DOS or Windows 3.11.
-
-
-''Video-CDs'' can be directly played on DVD-devices.
-
-
-Section 2.8 lists the availability of the mentioned software.
-
-
-
-

-
-!!1.7 Mailing Lists
-

-If you want to join the development team (with the intention
-to actively ''help'' them), send e-mail to
-cdwrite-request@other.debian.org and put the word subscribe in

-
-!!2. Setup the Linux-system for writing CD-ROMs
-
-
-
-
-
-This section applies to the following types of CD-writers: SCSI, IDE/ATAPI
-and the devices for the parallel port. USB CD-writers are not supported as
-of May 2000. Non-SCSI writers require compatibility
-drivers, which make them appear as if they were real SCSI devices. On the
-one side such a unifying strategy is easy ("everything is SCSI"), because
-on the application level you can share your knowledge with other users
-regardless of their kind of CD-writer. On the other side, you have to
-reconfigure applications like audio CD players or the mount utility to
-reflect the change of the driver name. For example, if you accessed your
-ATAPI CD-writer through the device file /dev/hdc before, you will have to
-access it through /dev/scd0 after activating the SCSI compatibility
-drivers.
-
-
-Once you succeed setting up your hardware and the rest of your Linux-system,
-the command cdrecord -scanbus shows you a list of devices
-on your SCSI busses.
-The goal of this section is to guide you in setting
-up your Linux-system, so that you finally end up seeing something like:
-
-
-
-
-

-''Listing: Detecting devices on your SCSI bus''
-
-
-
-The example was provided by Joumlrg Schilling and shows a total of four
-CD-writers. Please note that -scanbus also reports other devices,
-e.g. regular CD-ROMs and hard disk drives. The last column gives the SCSI
-description of the device, from which you cannot clearly distinguish
-ordinary CD-ROM drives from those with burning capability. But the product
-identification (middle column) often has hints about the feature in form of
-a R, -R or -RW.
-
-
-
-
-
-
-
-!!2.1 Quickstart
-
-
-
-This section is an attempt to provide an fast and easy description of the
-configuration. Not all possible setups are covered, but please go on and
-try it out anyways. First of all, check the Linux kernel version printed by
-the command "uname -r". It should be something like 2..X or 2.2.Y, where
-X is higher than 36 and Y is higher than 11. If you run older versions or
-the so called development kernels, you are on your own. Installing a new
-kernel is as much work as fixing an old one, so I have removed all hints
-you need for buggy kernels.
-
-
-The listing below shows a set of commands you could start with. The
-commands create device file entries under /dev unless they already exists.
-
-
-
-
-
-test `whoami` = 'root' || echo "You must be root to execute the commands."
-cd /dev/
-umask -S u=rwx,g=rwx,o-rwx
-
[[ -f loop0
] \
-|| ./MAKEDEV loop \
-|| for i in 0 1 2 3 4 5 6 7; do mknod loop$i b 7 $i; done
-[[ -f sg0 -o -f sga ] \
-|| ./MAKEDEV sg \
-|| for i in 0 1 2 3 4 5 6 7; do mknod sg$i c 21 $i; done
-
-''Listing: creating of devicefiles''
-
-
-
-Hardware access is usally implemented through device files under Linux. So
-before any other thing you make sure those files do exists in the
-directory /dev. Still nobody could give me a compelling reason why this has
-not been automated through techniques like the device filesystem
-(devfs). The devfs is available for years know, brings a safer (!) and a far
-clearer naming of devices and makes the device entries appear automatically
-under /dev. Some prominent people argue devfs is not the perfect solution,
-but they do not come up with anything better, not even something comparable
-and last but least nothing available and tested now. Lets start to use
-devfs, so I can remove the above commands from this document. (
-http://www.atnf.CSIRO.AU/~rgooch/linux/kernel-patches.html)
-
-
-
-
-
-Next thing to ensure is, that the Linux kernel is equiped with the
-necessary drivers. The following commands check various files for the
-presence of drivers in the running Linux kernel. Usally the command
-"cdrecord -scanbus" should trigger an automatic loading of all drivers. In
-case a driver is not present in the kernel afterwards, it is reported and
-the modularized driver (module) is manually loaded through insmod.
-
-
-
-
-
-
-
-
-test `whoami` = 'root' || echo "You must be root to execute the commands."
-cdrecord -scanbus > /dev/null
-if ! (pidof kerneld || test -f "/proc/sys/kernel/modprobe"); then
-echo "Neither kerneld nor kmod are running to automatically load modules".
-fi
-report_no_autoload() {
-echo "Ensure the module $1 is loaded automatically next time."
-}
-if test ! -f "/proc/scsi/scsi"; then
-report_no_autoload scsi_mod && insmod scsi_mod
-fi
-if ! grep "^........ sg_" /proc/ksyms > /dev/null; then

-
-Now to the people with CD-writers for IDE/ATAPI. As
-written in the previous chapter, you have to load the compatibility driver
-ide-scsi. But this driver can only access your CD-Writer if no other
-driver has already done so. In other words, you have to tell the
-regular IDE driver to leave your CD-writer unrecognized, so the ide-scsi
-driver can grab it.

-The table above shows the relation of device file names and the placing of

-has to be passed to the driver in the Linux kernel. Example: hdb=ide-scsi.

-statically compiled into your kernel, which seems to be the most common
-setup. If you need to pass more than one parameter to the kernel,

-the relevant append-line. Please note the append- and cmdline-entries

-!Special notes about SCSI CD-writers
-
-
-
-
-
-Please make sure that your writer is recognized by the BIOS of your SCSI
-hostadaptor card. Every SCSI hostadaptor scans the SCSI bus after power on
-and reports all devices found connected to the bus. The report includes
-the SCSI ID of the devices and their product label. It makes no sense
-to proceed unless your CD writer is listed in that report.
-
-
-If you plan to connect your SCSI device through the parallel port (not to
-confuse with the IDE drives for the parallel port), you need a special
-active cable and a special kernel driver. Read
-http://www.torque.net/parport/parscsi.html to learn more about this
-option.

-!Compiling missing kernel modules (optional)
-
-
-
-
-
-You don't need to read this section if you hardware is already sucessfully
-recognized and configured by the previously described configuration steps.
-
-
-The Linux kernel can be equipped with drivers for various features. You can
-compile the drivers into the kernel image statically or you can compile
-them as a module for on-demand loading. The last method is preferred for
-drivers not essential for bringing your Linux-system into life, because
-your kernel will be smaller and faster then. However, some drivers are
-essential for the system to come up and you shouldn't compile them as a
-module. Example: if your system lives on an IDE hard disk, you must have the
-driver for IDE hard disks in the kernel -- not as a module.
-
-
-There are three different types of CD-writers: SCSI, IDE/ATAPI and external
-writers that work through the parallel port. The table shows how to
-configure the Linux kernel for those hardware types. The first column of
-the table is the section of the kernel configuration menu, where you can
-find the setting. The second column is the description of the feature
-(taken from the kernel configuration menu, too). The third column gives the
-name of the resulting module. The columns named SCSI, IDE and PP contain
-the necessary options for the associated hardware (PP = parallel port).

-Y stands for yes and means you should put the beast into the kernel. M
-stands for module and means you should or must compile this feature as a
-module. Y/M gives you the option to decide between either (order indicates
-choices with less potential problems). Empty settings don't need to be
-modified and not changing them increases the chance that the resulting
-kernel will work for you (if it did before...). Especially in environments
-where SCSI and ATAPI devices are mixed, you better build most things as
-modules.
-
-
-Compiling loopback device is optional. It allows you to test the image
-before writing it to the media. If you want to be able to read CD-ROMs, you
-need support for the ISO 9660 filesystem. This driver automatically
-includes !RockRidge Extensions. The Microsoft Joliet CD-ROM extensions have
-to be explicitly added to the ISO 9660 filesystem. In any case, you need a
-low-level driver for your hardware. Low-level refers to the driver, which
-interacts directly with the hardware. For SCSI and the parallel port,
-there are a lot of low-level drivers available.
-
-
-Installing the resulting Linux-kernel is beyond the scope of this
-HOWTO. Please consult the documentation of your Linux-distribution.
-
-
-Users of !RedHat Linux be aware that you have to compile in the
-features "Ramdisk support" and "Initial ramdisk". Furthermore, you
-have to generate a new ramdisk with the new modules by issuing a
-command like "mkintrd --preload ide-cd initrd-2.2.14.img 2.2.14".

-!!3. Burning CD-Rs
-
-
-
-
-''"If to smoke you turn I shall not cease to fiddle while you burn."''
-(Roman emperor Nero about burning his own classic-CDs, AD64. He
-misunderstood it completely and burned Rome down.)
-
-
-
-
-
-
-Writing CD-ROMs consists of two steps under Linux:
-
-
-
-
-
-* packaging the desired data (files, music or both) into files
-with special formats
-*
-
-* writing the data from the files to the CD-R with the utility cdrecord
-*
-
-
-
-This chapter describes the steps for data and audio CDs in greater detail.
-
-
-
-
-
-
-
-!!3.1 Writing CD-ROMs (pure data)
-
-
-
-Note that collecting the data to put onto a CD usually takes longer than one
-expects. Consider that missing files cannot be added once the CD is
-written and fixated. This is also true for CD-RW, which can currently
-only be rewritten as a whole. Using the multi-session feature is no
-option for single files, as it consumes much space for a new complete
-table of contents (TOC). UDF is not ready yet for Linux.
-
-
-Also keep in mind that a certain amount of the free space of a CD is used
-for storing the information of the ISO-9660-filesystem (usually a few MB).
-620 MB data will always fit on a 650 MB CD-R.
-
-
-
-
-!Creating an image of the later CD-ROM
-
-
-Before any storage medium (e.g. floppy disk, hard disk or CD) can be used,
-it must get a filesystem (DOS speak: get formatted). The filesystem is
-responsible for organizing and incorporating the files that should be
-stored on the medium.
-
-
-The usual utilities for creating filesystems on hard disk partitions write an
-empty filesystem onto them, which is then mounted and filled with files by
-the users as they need it. A writable CD is only writable once so if we
-wrote an empty filesystem to it, it would get formatted and remain
-completely empty forever. This is also true for rewritable media as you
-cannot change arbitrary sectors yet; you must erase their whole content.
-
-
-So what we need is a tool that creates the filesystem while copying the
-files to the CD. This tool is called mkisofs. A sample usage
-looks as follows:
-
-
-
-
-
-mkisofs -r -o cd_image private_collection/
-`---------' `-----------------'
-| |
-write output to take directory as input
-
-
-
-
-The option '-r' sets the permissions of all files to be public readable on
-the CD and enables !RockRidge-extensions. You probably want to use this option
-unless you really know what you're doing
-(hint: without '-r' the mount point gets the permissions of
-private_collection!).
-
-
-mkisofs will try to map all filenames to the 8.3 format used by
-DOS to ensure the highest possible compatibility. In case of naming conflicts
-(different files have the same 8.3 name), numbers are used in the filenames
-and information about the chosen filename is printed via STDERR (usually
-the screen). Don't panic: Under Linux you will never see these odd 8.3
-filenames because Linux makes use of the Rock Ridge extensions which
-contain the original file information (permissions, filename, etc.).
-
-
-Remeber do use the Option -J (MS Joliet extensions) or use mkhybrid if you
-want to generate a more Windows-friendly CD-ROM. For HFS CD-ROMS used on
-the Macintosh, you better read the man-page of mkisofs' bigger sister
-mkhybrid for details on various options.
-
-
-Now you may wonder why the output of mkisofs is not directly sent
-to the writer device. There are three reasons:
-
-
-
-
-
-*mkisofs knows nothing about driving CD-writers.
-*
-
-*You may want to test the image before burning it.
-*
-
-*On slow machines it would not be reliable (see section 4.).
-*
-
-
-
-There is a method to write a CD-R in one go, which will be described below.
-
-
-One also could think of creating an extra partition and writing the image
-to that partition instead to a file. I vote against such a strategy because
-if you write to the wrong partition due to a typo, you can lose your
-complete Linux system. Read: that happened to me... Furthermore, it is a
-waste of disk space because the CD-image is temporary data that can be
-deleted after writing the CD. However, using raw partitions saves you the
-time for deleting files of 650 MB size.
-
-
-
-
-
-
-
-!Test the CD-image
-
-
-Linux has the ability to mount files as if they were disk partitions. This
-feature is useful to check that the directory layout and file access
-permissions of the CD image matches your wishes. Although media is very
-cheap today, the writing process is still time consuming, and you may at
-least want to save your time by doing a quick test.
-
-
-To mount the file cd_image created above on the directory
-/cdrom, give the command
-
-
-
-
-
-mount -t iso9660 -o ro,loop=/dev/loop0 cd_image /cdrom
-
-
-
-
-Now you can inspect the files under /cdrom -- they appear exactly
-as they were on a real CD. To umount the CD-image, just say umount
-/cdrom. (Warning: On Linux kernels prior to 2..31 the last file on
-/cdrom may not be fully readable. Please use a more recent kernel
-like 2..36. The option -pad for cdrecord applies to audio CDs only and the
-option -pad for mkisofs requires a patch, which is as much work
-to apply than to upgrade to a bug-free Linux kernel.)
-
-
-Note:
-
-Some ancient versions of mount are not able to deal with
-loopback devices. If you have such an old version of mount, then upgrade your Linux-system.
-Several people have already suggested putting information about how to get the
-newest mount utilities into this HOWTO. I always refuse this. If your
-Linux distribution ships with an ancient mount, report it as a
-bug. If your Linux distribution is not easily upgradable, report it as a
-bug.
-
-If I include all the information that is necessary to work around bugs
-in badly designed Linux distributions, this HOWTO would be a lot bigger and
-harder to read.
-
-
-
-
-
-
-
-
-!Write the CD-image to a CD
-
-
-This section only covers writing data CDs in TAO mode, because it is the
-most frequently used mode for data. For more information about the
-differences of TAO and DAO, please see the chapter about audio CD-Rs. If
-you use DAO mode with the tool cdrdao, then remember to add a dummy audio
-track at the end of the TOC file (see the README).
-
-
-Not much more left to do. If you haven't already tried, it's a good time for
-the command
-
-
-
-
-
-cdrecord -scanbus
-
-
-
-
-This will tell you to which SCSI device your CD-writer is attached to. All
-other methods of guessing the information printed so nicely by cdrecord
-have been removed from the HOWTO.
-
-
-Before showing you the last command, let me warn you that CD-writers want
-to be fed with a constant stream of data. So the process of writing the CD image to the CD must not be
-interrupted or a corrupt CD will result. It's easy to interrupt the
-data stream by deleting a very large file. Example: if you delete an old
-CD-image of 650 Mbytes size, the kernel must update information about
-650,000 blocks on the hard disk (assuming you have a block size of 1 Kbyte for
-your filesystem). That takes some time and is very likely to slow down
-disk activity long enough for the data stream to pause for a few seconds.
-However, reading mail, browsing the web, or even compiling a kernel
-generally will not affect the writing process on modern machines.
-
-
-Please note that no writer can re-position its laser and continue at
-the original spot on the CD when it gets disturbed. Therefore any strong
-vibrations or other mechanical shocks will probably destroy the CD you are
-writing.
-
-
-When you are mentally prepared, dress up in a black robe, multiply the
-SCSI-id of the CD-writer with its SCSI-revision and light as many candles,
-speak two verses of the ASR-FAQ (newsgroup alt.sysadmin.recovery) and
-finally type:
-
-
-
-
-
-shell> SCSI_BUS=0 # taken from listing 1 "scsibus0:"
-shell> SCSI_ID=6 # taken from listing 1 "TOSHIBA XM-3401"
-shell> SCSI_LUN=
-shell> cdrecord -v speed=2 dev=$SCSI_BUS,$SCSI_ID,$SCSI_LUN \
--data cd_image
-# same as above, but shorter:
-shell> cdrecord -v speed=2 dev=,6,0 -data cd_image
-
-
-
-
-For better readability, the coordinates of the writer are stored in three
-environment variables with natural names: SCSI_BUS, SCSI_ID, SCSI_LUN.
-
-
-If you use cdrecord to overwrite a CD-RW, you must add the option
-"blank=..." to erase the old content. Please read the man page to learn
-more about the various methods to blank the CD-RW.
-
-
-In times where everybody except me owns a 400 Mhz machine, people feed the
-output of mkisofs directly into cdrecord:
-
-
-
-
-
-shell> IMG_SIZE=`mkisofs -R -q -print-size private_collection/ 2>&1 \
-| sed -e "s/.* = //"`
-shell> echo $IMG_SIZE
-shell> [[ "$IMG_SIZE" -ne 0 ] && mkisofs -r private_collection/ \
-|cdrecord speed=2 dev=,6,
-tsize=${IMG_SIZE}s -data -
-# don't forget the s --^ ^-- read data from STDIN
-
-
-
-
-The first command is an empty run to determine the size of the image (you
-need the mkisofs from the cdrecord distribution for this to work). You need
-to specify all parameters you will use on the final run (e.g. -J or -hfs).
-Maybe your writer does not need to know the size of the image to be
-written, so you can leave this dry run out. The printed size must be passed
-as a tsize-parameter to cdrecord (it is stored in the environment variable
-IMG_SIZE). The second command is a sequence of mkisofs and cdrecord,
-coupled via a pipe.
-

-!!3.2 Writing audio CDs
-
-
-
-Writing audio CDs is very similar to the steps described above for data
-CDs. You can choose between two techniques: DAO or TAO. TAO (track at
-once) is less suitable for music, because you will hear clicks between the
-individual tracks. It is described first anyways, because it is a little bit
-easier to deal with and DAO is not available for all drives yet.
-
-
-The main difference compared to writing data CD-Rs is the format of the
-images. ISO-9660 (or whatever filesystem you prefer) would not be suitable,
-because no audio CD player is able to deal with filesystems. Instead the
-audio data must be writen as "16 bit stereo samples in PCM coding at 44100
-samples/second (44.1 kHz)".
-
-
-One utility to convert your sound files into the required format is sox.
-Its usage is straightforward:
-
-
-
-
-
-shell> sox killing-my-software.wav killing-my-software.cdr
-
-
-
-
-This command would convert the song killing-my-software from the WAV-format
-into the CDR audio-format. See the man page for sox for more details about
-formats and filename-extensions sox recognizes. Because the output of the
-manual conversion takes up much disk space, it was made a built-in feature
-of cdrecord for the sound formats WAV and AU. So as long as your sound
-files have the extensions .wav or .au (and the sample rate "stereo, 16 bit,
-44.1 kHz"), you can use them as audio tracks without manual conversion into
-the CDR format. However, cdrecord requires
-the size of the sound data to be a integer multiple of 2352 and to be
-greater than 705,600 bytes, which is not fullfilled for some WAV files. For
-such files the usage of sox is needed to pad the audio data up to 2352
-bytes.
-
-
-
-
-!Writing audio CDs (TAO)
-
-
-
-
-
-An audio CD consists of audio tracks, which are organized as separate
-images when using TAO mode. So if you want to have ten tracks on your CD,
-you have to make ten images.
-
-
-Cdrecord writes CD images as audio tracks if the option -audio is
-specified. The other options are identical to those used for writing
-data-CDs (unless you have very special requirements). These three examples
-all do the same thing, but read the tracks from different sound file formats:
-
-
-
-
-
-shell> cdrecord -v speed=2 dev=,6,0 -audio track1.cdr track2.cdr...
-shell> cdrecord -v speed=2 dev=,6,0 -audio track1.wav track2.wav...
-shell> cdrecord -v speed=2 dev=,6,0 -audio track1.au track2.au...
-
-
-
-
-By doing this, you will produce an audio CD which has a 2
-seconds of pause between audio tracks.
-One notable format not directly readable by cdrecord is MPEG Layer 3. To
-convert files in this format to the CDR-format, you can use the command
-"mpg123 --cdr - track1.mp3 > track1.cdr". The option --cdr ensures the
-track is encoded in the required format (see above). Older versions of
-mpg123 require -s instead of the plain - to write to stdout. The other
-direction (converting from WAV to MPEG) can be done with LAME for WAV-files
-(extract the track with cdda2wav from the audio CD and encode it into MP3
-with the help of LAME).
-
-
-To create a CD-R from a whole bunch of MP3-files, you can use the following
-command sequence:
-
-
-
-
-
-for I in *.mp3
-do
-mpg123 --cdr - "$I" | cdrecord -audio -pad -nofix -
-done
-cdrecord -fix
-
-
-
-
-Depending on the speed of your machine, you may want to slow down writing
-to "speed=1" (cdrecord option). If you use "speed=4", your machine must be
-able to play the MP3-file at quadruple speed. mpg123 consumes much
-CPU-time! If you are in doubt, try an empty run with -dummy (keeps the
-laser switched off).
-
-
-
-
-!DAO
-
-
-If you want to get rid of the pauses between the audio tracks, you have to
-use disk-at-once (DAO) recording versus the (individual)
-track-at-once (TAO) recording described above. Support for DAO is currently
-most advanced in cdrdao. Please see its homepage for details.
-
-
-If you master the CD in DAO mode, then you use a monolithic image (sound
-file) and control track information with a configuration file.

-!!3.3 Mixed mode CD-ROMs
-
-
-
-
-
-
-There is not much to say about this topic. Just indicate the type of the
-(subse quent) images with the options -data and -audio. Example:
-
-
-
-
-
-cdrecord -v dev=,6,0 -data cd_image -audio track*.cdr

-
-!!4. Dear Winfried,...
-
-
-This is the section usually known as "frequently asked
-questions with answers". If you have a problem with your partner, kids or
-dog, just send it in, as long as it is related to writing CD-Rs or is
-otherwise entertaining.
-
-
-
-
-!!4.1 How sensitive is the burning process?
-
-
-
-Test it. Use the option -dummy to do an empty run of cdrecord. Do
-everything you would do otherwise and watch if the burning process
-survives.
-
-
-If you feed cdrecord directly from mkisofs, then disk intensive processes
-such as updating the ''locate'' database lower the maximum flow rate
-and may corrupt the CD. You better check such processes are not started
-via cron, at or anacron while you burn
-CD-Rs on older machines.
-
-
-
-
-!!4.2 Has file fragmentation a bad impact on the throughput?
-
-
-
-Fragmentation of files is usually so low that its impact isn't noticed. However,
-you can easily construct pathological cases of fragmentation, which lower
-the throughput of your hard disks under 100 kbytes/second. So don't do
-that. :-)
-Yes, files on a hard disk get fragmented over the years. The faster, the
-fuller the filesystem is. Always leave 10% or 20% free space, and you
-should run fine with respect to writing CD-Rs.
-
-
-If you're uncertain then look at the messages printed while booting. The
-percentage of fragmentation is reported while checking the filesystems. You
-can check for this value with the very dangerous command
-
-
-
-
-
-shell> e2fsck -n /dev/sda5 # '-n' is important!
-[[stuff deleted -- ignore any errors]
-/dev/sda5: 73/12288 files (12.3% non-contiguous)
-
-
-
-
-In this example the fragmentation seems to be very high -- but there are
-only 73 very small files on the filesystem. So the
-value is ''not'' alarming.
-
-
-There is an experimental utility called e2defrag to defragment extended-2
-filesystems. The current version does not work reliable enough to use
-it even for private environments. If you really want to defragment your
-filesystem, make a backup copy (better: two copies), practice restoring the
-data, then create a new filesystem (that will destroy the old) and restore the
-data. This sketch is currently the safest technique.
-
-
-
-
-
-
-
-!!4.3 Is it possible to store the CD-image on an UMSDOS-filesystem?
-
-
-
-Yes. The only filesystem that isn't reliable and fast enough for writing
-CD-ROMs from is the ''network filesystem'' (''NFS'').
-I used UMSDOS myself to share the disk-space between Linux and DOS/Win
-on a PC (486/66) dedicated for writing CD-ROMs.
-
-
-
-
-
-
-
-!!4.4 Isn't there some way to get around the ISO-9660 limitations?
-
-
-
-Yes. You can put any filesystem you like on the CD. But other operating
-systems than Linux won't be able to deal with this CD.
-Here goes the recipe:
-
-
-
-
-
-*Create an empty file of 650MB size.
-
-
-dd if=/dev/zero of="empty_file" bs=1024k count=650
-
-
-
-*
-
-*Create an extended-2 filesystem on this file
-
-
-shell> /sbin/mke2fs -b 2048 empty_file
-empty_file is not a block special device.
-Proceed anyway? (y,n) y
-
-
-
-*
-
-*Mount this empty file through the loopback devices (you need a reasonable new mount for this; read above).
-
-
-mount -t ext2 -o loop=/dev/loop1 empty_file /mnt
-
-
-
-*
-
-*Copy files to /mnt and umount it afterwards.
-
-*
-
-*Use cdrecord on empty_file (which is no
-longer empty) as if it were an ISO-9660-image.
-*
-
-
-
-If you want to make an entry in /etc/fstab for such
-a CD, then disable the checking of the device file on system
-startup. For example:
-
-
-
-
-
-/dev/cdrom /cdrom ext2 defaults,ro 0
-
-
-
-
-The first 0 means "don't include in dumps" (backup), the second
-(=important) one means "don't check for errors on startup" (fsck would fail
-to check the CD for errors).
-
-
-
-
-
-
-
-!!4.5 How to read the tracks from audio CDs?
-
-
-
-There are several software packages available. The newest one is
-"cdpranoia" and can be downloaded from
-
-
-
-
-http://www.xiph.org/paranoia/
-
-
-
-
-
-Or you want to try the combination of "cdda2wav" and "sox", available from
-sunsite and its mirrors:
-
-
-
-
-ftp://sunsite.unc.edu/pub/Linux/apps/sound/cdrom/cdda2wav0.71.src.tar.gz
-
-
-ftp://sunsite.unc.edu/pub/Linux/apps/sound/convert/sox-11gamma-cb3.tar.gz
-
-
-cdda2wav enables you to get a specific interval (or a whole track)
-from your audio CD and converts it into a .wav-file. sox converts
-the WAV files back into the (audio CD) cdda-format so it can be written to
-the CD-R using cdrecord. You don't necessarily need sox if
-you use a recent version of cdrecord, because it has built-in
-support for .au and .wav files.
-
-
-
-
-
-
-
-!!4.6 How to probe for SCSI devices after boot?
-
-
-
-The file drivers/scsi/scsi.c contains the information
-
-
-
-
-
-/*
-* Usage: echo "scsi add-single-device 0 1 2 3" >/proc/scsi/scsi
-* with "0 1 2 3" replaced by your "Host Channel Id Lun".
-* Consider this feature BETA.
-* CAUTION: This is not for hot plugging your peripherals. As
-* SCSI was not designed for this you could damage your
-* hardware !
-* However perhaps it is legal to switch on an
-* already connected device. It is perhaps not
-* guaranteed this device doesn't corrupt an ongoing data transfer.
-*/
-
-
-
-
-Please note that this should only be used if your add SCSI devices to the
-end of the chain. Inserting new SCSI devices into an existing chain
-disturbs the naming of devices (directory /dev) and may destroy the
-complete content of your hard disk.
-
-
-Some kernel versions do not like re-scanning the SCSI bus at all and your
-system may freeze solid when trying out the above. You have been warned.
-
-
-
-
-!!4.7 Is it possible to make a 1:1 copy of a data CD?
-
-
-
-
-
-
-
-
-
-
-
-
-Yes. But you should be aware of the fact that any errors while reading the
-original (due to dust or scratches) will result in a defective copy.
-Please note that both methods will fail on audio CDs! You have to use cdrdao or
-cdda2wav on audio CDs.
-
-
-First case: you have a CD-writer and a separate CD-ROM drive. By issuing the
-command
-
-
-
-
-
-cdrecord -v dev=,6,0 speed=2 -isosize /dev/scd0
-
-
-
-
-you read the data stream from the CD-ROM drive attached as
-/dev/scd0 and write it directly to the CD-writer.
-
-
-Second case: you don't have a separate CD-ROM drive. In this case you have
-to use the CD-writer to read out the CD-ROM first:
-
-
-
-
-
-dd if=/dev/scd0 of=cdimage
-
-
-
-
-This command reads the content of the CD-ROM from the device /dev/scd0 and
-writes it into the file "cdimage". The contents of this file are equivalent
-to what mkisofs produces, so you can proceed as described earlier
-in this document (which is to take the file cdimage as input for cdrecord).
-If you want to see a progress-meter and other fancy stuff, then you can also
-use Joumlrg Schillings sdd.
-
-
-In case you run into errors, then install a recent version of cdrecord,
-which ships a tool called "readcd" (found under misc/). It gives you the
-same result as dd, but reads sectors on the CD-ROM several times in case
-of errors.
-
-
-
-
-
-
-
-!!4.8 Can Linux read Joliet CD-ROMs? (obsolete answer)
-
-
-
-Yes. Newer Kernels (2..36 and the upcoming 2.2) have built-in support for
-the joliet format. Remember you have to use both options in your
-/etc/fstab: the keywords iso9660 and joliet (later is really an extension).
-For more details, see
-http://www-plateau.cs.berkeley.edu/people/chaffee/joliet.html.
-
-
-
-
-
-
-
-!!4.9 How do I read/mount CD-ROMs with the CD-writer?
-
-
-
-Just as you do with regular CD-ROM drives. No tricks at all. Note that you
-have to use the scd devices (SCSI CD-ROM) to mount CD-ROMs for reading,
-even if you have an ATAPI CD-ROM (remember you configured your
-ATAPI devices to act like SCSI). Example entry for /etc/fstab:
-
-
-
-
-
-/dev/scd0 /cdrom iso9660 ro,user,noauto 0
-
-
-
-
-
-
-
-
-
-!!4.10 How to put even more data on the CD-R?
-
-
-
-Use bzip2 instead of any other compressor like gzip or
-pkzip. It will save you up to 30% of disk-space for larger
-(>100kb) files. You can download it from
-
-
-
-
-http://www.muraroa.demon.co.uk/
-
-
-
-
-
-
-
-
-Instead of writing a true audio CD, you can optionally convert your
-WAV audio files into MP3 audio files and store them on a ISO-9660
-filesystem as regular files. Usually MPEG III give you a compression of
-1:10. Of course, most CD-players are not able to read files... this is the
-drawback. On the other hand, why not running the music for your next party
-from hard disk? 18 Gbytes are enough for 3000-4000 titles. :-)
-
-
-A software MPEG III-encoder is available from
-
-http://www.sulaco.org/mp3/
-
-
-
-
-
-A MPEG III-player is available from
-
-http://www.mpg123.org/

-For recorded speech, you may want to try to reduce its size using
-shorten or "GSM lossy speech compression":

-!!4.11 How to make bootable CD-ROMs?
-
-
-
-You must have an 1.44 MB bootable floppy-disk. Create an exact image of
-this floppy-disk by issuing the command
-
-
-
-
-
-dd if=/dev/fd0 of=boot.img bs=18k
-
-
-
-
-Place this floppy image into the directory holding the collection of your
-files (or into a subdirectory of it, just as you like). Tell mkisofs about
-this file with the option '-b' and also use '-c'. For details read the file
-README.eltorito in the mkisofs-distribution.
-
-
-An interesting application for a custom bootable CD is as a virus safe DOS-
-or Windows-system. It saves you the money for the hard disks (if you have a
-network and use samba to put the user-data on a file server). The German
-computer magazine c't has a article about this issue in the issue 11/99,
-page 206 (
-http://www.heise.de/).
-
-
-Some details about the bootable !RedHat CD-ROM is available from
-http://members.bellatlantic.net/~smithrod/rhjol-technical.html.
-
-
-
-
-!!4.12 How to make CD-ROMs writable like a hard disk?
-
-
-
-There is an ''overlay filesystem'' available for Linux, which is
-mounted over the CD-ROM and intercepts all writing operations. New and
-modified files are stored elsewhere, but for the user it looks like the
-CD-ROM is modified. For more information, see
-http://home.att.net/~artnaseef/ovlfs/ovlfs.html.
-
-
-If that is not enough for your needs: wait for the UDF-filesystem to be
-supported by Linux or help developing it (see
-http://trylinux.com/projects/udf/. At the moment only reading of
-CD-media is supported due to a limitation in the CD-ROM drivers of the
-Linux kernel.
-
-
-
-
-
-
-
-!!4.13 Is it possible to use several writers at once?
-
-
-
-Yes. It is reported to work with at least 3 writers at full speed (6x) on a
-PC with 233 Mhz and a single SCSI bus running kernel 2.2.12. You need
-either a recent version of the Linux kernel (2.2.12 or higher).
-
-
-
-
-
-
-
-
-
-
-!!4.14 What about Solaris, *BSD, AIX, HP-UX, etc.? Is my variant of Unix supported?
-
-
-
-Only chapter 2 is Linux-specific. You can apply chapter 3 and 4 even if you
-run another family of operating systems than Linux. Please see the files
-README.NetBSD, README.aix, README.hpux, README.next,
-README.solaris, README.sunos, README.vms or README.xxxBSD from the
-cdrecord-distribution.
-
-
-Probably yes. Compile cdrecord for your platform and issue the command
-"cdrecord -scanbus". Read the README.* file for your Unix distributed with
-the sources of cdrecord. However, not all variants of Unix can read the
-!RockRidge, Joliet or HFS extensions on your newly written CD-R.
-
-
-
-
-
-
-
-!!4.15 Where to store the local configuration permanently?
-
-
-
-
-
-
-You have two options. Either you use the built-in configuration file for
-cdrecord, or you use a shell wrapper like the one shown below. This
-shell script reads a configuration file, which lists the options and
-parameters for cdrecord line by line. The names are exactly the same
-as on the command line, but without the leading dash. Comments are allowed.
-Example:
-
-
-
-
-
-# be verbose
-v
-# set the speed of the writer
-speed=2
-# the device-coordinates in the form BUS,ID,LUN
-dev=,6,
-
-
-
-
-The configuration files for the wrapper belong into /etc/cdrecord/
-and must be referenced on the command line. Example: if you want
-to refer to the configuration /etc/cdrecord/mywriter.cfg, then
-you can issue the command "cdrecord.sh mywriter.cfg -audio track1...".
-Everything after mywrite.cfg is passed to cdrecord.
-
-
-
-
-
-#! /bin/bash
-CFGDIR="/etc/cdrecord"
-CFG="$1"
-shift
-ARGS_LEFT="$@"
-if [[ ! -f "$CFGDIR/$CFG" ]
-then
-echo "Configuration file $CFGDIR/$CFG not found. Exiting."
-exit 1
-fi
-while read LINE
-do
-case $LINE in
-\#*|"") continue;;
-esac
-old_IFS="$IFS"
-IFS="$IFS="
-set -- $LINE
-IFS="$old_IFS"
-O_NAME="$1"
-O_VALUE=""
-while shift
-do
-case $1 in
-"") continue;;
-esac
-O_VALUE="$1"
-done
-if [[ -z "$O_VALUE" ]
-then
-O_CDRECORD="$O_CDRECORD -$O_NAME "
-continue
-fi
-O_CDRECORD="$O_CDRECORD $O_NAME=$O_VALUE "
-done < "$CFGDIR/$CFG"
-set -x #DEBUG
-exec cdrecord $O_CDRECORD $ARGS_LEFT
-echo "Execution of cdrecord failed."
-
-
-
-
-
-
-!!4.16 How can the CD-info be retrieved?
-
-
-
-Somewhere behind the first 32 k on the CD, a block with information about
-the CD is located. You can extract the information with the following
-shell script:
-
-
-
-
-
-#! /bin/bash
-RD=/dev/cdrom
-for i in 32768,7 32776,32 32808,32 32958,128 33086,128 33214,128 \
-33342,128 33470,32 33581,16 33598,16 33615,16 33632,16
-do
-old_IFS="$IFS"
-IFS=","
-set -- $i
-IFS="$old_IFS"
-OFFSET=$1
-LENGTH=$2
-echo "*`dd if=$RD bs=1 skip=$OFFSET count=$LENGTH 2> /dev/null`#"
-done
-
-
-
-
-
-
-
-
-
-!!4.17 What about re-writing
-
-
-
-When overwriting CD-RW media, specify the parameter blank=fast to
-cdrecord. That's all. See the man page of cdrecord for details about this
-parameter.
-
-
-
-
-!!4.18 How to create a multi-session CD?
-
-
-
-First of all, the image for a multi-session CD must be formatted using the
-ISO-9660 filesystem using !RockRidge-extensions. And you must use the option
--multi for cdrecord as long as you want to add further sessions. So at
-least for the first session, you must specify the option -multi.
-
-
-Some CD-writers have no support for CD-ROM XA mode 2 or for session-at-once
-(SAO), so you need to specify the switch -data for cdrecord on the command
-line.
-
-
-The images for the second and subsequent sessions are a little bit more
-complicated to generate. Mkisofs must know where the free space on the
-CD-R begins. That information can be gathered by using the option -msinfo
-on cdrecord (see example below).
-
-
-
-
-
-shell> NEXT_TRACK=`cdrecord -msinfo dev=,6,`
-shell> echo $NEXT_TRACK
-shell> mkisofs -R -o cd_image2 -C $NEXT_TRACK -M /dev/scd5
-private_collection/ \
-
-
-
-
-For more information, please read the file README.multi, which is
-distributed with cdrecord.
-
-
-
-
-!!4.19 Should I use the SCSI adapter shipped with the writer?
-
-
-
-Reported via email: Most CD-writer docs say to use a separate SCSI bus
-if going from a CD-ROM to a CD-writer and I have seen this myself in
-the following scenario:
-
-
-Adaptec 2940UW SCSI card, a 24x SCSI CD-ROM and a 4x4 SCSI CD-writer. When
-I got the CD-writer, it came with its own ISA SCSI card which could only
-handle one device. I figured I'd toss this and use my better adaptec card
-for all the stuff. I noticed it was quite prone to buffer under-runs when
-recording at the 4x speed, but as soon as I tried hooking up the ISA SCSI
-card, it had no problems. I know 2 other people (both using adaptec 2940
-cards), who have experienced exactely the same symptoms, usually when writing
-from a CD-ROM to a CD-recorder. Though I've never experienced the problem
-when going from a hard drive to a CD-writer on the same bus.
-
-
-
-
-
-
-
-!!4.20 How to burn over the network?
-
-
-
-Usally a file transfer with FTP is fast enough to feed a CD-recorder at
-quadruple (4x) speed even over a 10 Mbit ethernet. You can couple the
-ftp-client and cdrecord via a fifo. First create a fifo named cdimage:
-
-
-
-
-
-mkfifo cdimage
-ftp other.host.org
-get cdimg cdimage
-
-
-
-
-Then treat cdimage like a regular file, i.e. issue the following command:
-
-
-
-
-
-cdrecord dev=,1,0 speed=2 cdimage
-
-
-
-
-Your ftp-client will notice when cdrecord wants to read from the file and
-will start transfering data from the ftp-host.
-
-
-
-
-
-
-
-!!4.21 I hear a crack or click sound at the end of the each track.
-
-
-
-You have to use disk-at-once mode (DAO) to get rid of the cracks.
-
-
-
-
-
-
-
-!!4.22 How can this be set up so that a user can burn CDs instead of always
-being root?
-
-
-You can add the setuid-bit to the cdrecord-executable. However, this might
-be a security risk. Just setting the permissions on the device files does
-not help as cdrecord issues privileged commands via the SCSI generic
-interfaces.
-
-
-
-
-
-which cdrecord
-chown root.root /usr/bin/cdrecord
-chmod 4111 /usr/bin/cdrecord
-
-
-
-
-
-
-
-
-
-!!4.23 Where do I get the "Yellow Book" and "Orange Book" standards?
-
-
-
-You get the printed specifications from Philips and they are expensive.
-
-
-
-
-
-
-
-!!4.24 I've been searching for information on burning Video-CD under Linux.
-
-
-
-
-
-
-Here you can find utilities for creation of MPEG videos and Video-CDs:
-http://www.mainconcept.de/
-
-
-http://www.johanni.de/munich-vision/vcd/
-
-Political correct people mention the Berkeley-tools and other
-YUV-strategies. Their usage is complicated, takes much time and
-harddisk-space and gives you no audio track. I recommend to
-use conceptually higher level applications like the ones mentioned
-above.
-
-
-
-
-
-
-
-!!4.25 Which is easier to set up, IDE or SCSI?
-
-
-
-SCSI CD-writers are slightly easier to set up with regard to CD-writing
-under Linux. And they are reported to have better error recovery. If that
-outweights the higher price cannot be answered generally.
-
-
-
-
-
-
-
-!!4.26 How can I overburn a CD using {cdrecord,cdrdao}?
-
-
-
-Overburning a CD-R is nothing special. It is at your own risk that the data
-fits on the CD-ROM, but thats all. There are no 650 Mbytes-limits in the
-software under Linux.
-
-
-
-
-
-
-
-!!4.27 What will cdrecord do when it stops getting input from the pipe?
-
-
-
-It will finish writing. So you can just couple your favourite backup tool
-with cdrecord using a pipe, like in "bru -size=640m -f - | cdrecord
-dev=,1,0 speed=2 -". You have to take special care within the backup
-utility if the backup spans multiple CD-Rs.
-
-
-
-
-
-
-
-!!4.28 Is there an equivalent to ignore=hdX for the ide-scsi emulation?
-
-
-
-I know of no way, but anybody is welcome to add this feature to the
-Linux kernel sources.
-
-
-
-
-
-
-
-!!4.29 How many times can you re-use CD-RW before they become faulty?
-
-
-
-Good question.
-
-
-
-
-
-
-
-!!4.30 Which format to choose for a platform independant CD-ROM?
-
-
-
-A CD-ROM to be read by all systems can only use the plain ISO 9660
-format. That means stupid 8+3 filenames from old MS-DOS and without any HFS
-(Macintosh), Joliet (Microsoft) or !RockRidge (newer Unices) extensions.
-There is no extension for longer filenames, which could be read by all
-operating systems.
-
-
-
-
-
-
-
-!!4.31 Is multi-session for audio tracks possible?
-
-
-
-Audio CD-players are only able to deal with audio tracks stored in the first
-session. In other words, you cannot add audio tracks using subsequent
-sessions. However, writing data tracks into the second session effectively
-hides them from audio CD-players. This way you prevent having an silent
-track on your mixed mode CD (audio and data mixed).
-
-
-
-
-
-
-
-!!4.32 What hardware resources do I need? Is an old Pentium enough?
-
-
-
-An answer depends on your wishes. If you need a reason to buy a new
-computer, here is the answer from the international association of computer
-manufactures: Whatever you plan to do, you need a processor with 800
-Mhz. Because it won't fit into your existing motherboard, you need a new
-motherboard, too. The easiest solution is just to buy the typical complete
-offer as seen in advertisements on TV. Please ignore the rest of this
-section.
-
-
-Now the case if you just want a rational answer: I wrote several CD-ROMs
-sucessfully using a "486" with 66 Mhz. Although MS does not consider them
-to be PCs anymore, but recommends to run a CE version on them (seen on the
-CeBIT), Linux runs even fine on the predecessors of the Pentium and is even
-able to write CDs. You can easily find out if the power of your hardware is
-sufficient for writing CD-ROMs by testing it out. Just add the command line
-switch -dummy when executing cdrecord and the laser will be kept off. Watch
-the burning process.

-
-!!5. Troubleshooting
-
-
-Always remember, that you can still use corrupt CD-ROMs as coasters. :-)
-
-
-
-
-!!5.1 It doesn't work: under Linux
-
-
-
-Please check first, that the writer works under the software it is shipped
-with (=under another operating system). Concretely:
-
-
-
-
-
-*Does the controller recognize the writer as a SCSI device?
-*
-
-*Does the driver software recognize the writer?
-*
-
-*Is it possible to make a CD using the accompanied software?
-*
-
-
-
-If "it doesn't even work" with the accompanied software you have a hardware
-conflict or defective hardware. If it works and you use loadlin to boot
-Linux, then that is a problem with loadlin. Loadlin makes a warm-boot with
-most of the hardware already initialized and that can confuse the Linux
-kernel.
-
-
-
-
-
-
-
-!!5.2 Error-message: No read access for 'dev=,6,'.
-
-
-
-Under Linux, some versions of the C-library are incompatible (buggy), so
-that an application linked against one version will not work with
-another. An example for an error triggered by pre-compiled binaries is the
-following:
-
-
-
-
-
-[[root@Blue /dev]# cdrecord -eject dev=,6,
-cdrecord: No such file or directory. No read access for 'dev=,6,'.
-
-
-
-
-The solution is to install a newer C-library.
-
-
-
-
-
-
-
-!!5.3 It doesn't work: under DOS and friends
-
-
-
-Try to use Linux. Installation and configuration of SCSI drivers
-for DOS is the hell. Linux is too complicated? Ha!
-
-
-
-
-
-
-
-!!5.4 SCSI errors during the burning phase
-
-
-
-Most likely those errors are caused by
-
-
-
-
-
-*missing dis-/reconnect feature on the SCSI bus
-*
-
-*insufficiently cooled hardware
-*
-
-*defective hardware (should be detected by 5.1.)
-*
-
-
-
-Under various circumstances SCSI devices dis- and reconnect themselves
-(electronically) from the SCSI bus. If this feature is not available (check
-controller and kernel parameters) some writers run into trouble during
-burning or fixating the CD-R.
-
-
-Especially the NCR 53c7,8xx SCSI driver has the feature disabled by
-default, so you might want to check it first:
-
-
-
-
-
-NCR53c7,8xx SCSI support [[N/y/m/?] y
-always negotiate synchronous transfers [[N/y/?] (NEW) n
-allow FAST-SCSI [[10MHz] [[N/y/?] (NEW) y
-allow DISCONNECT [[N/y/?] (NEW) y
-
-
-
-
-
-
-
-
-
-!!5.5 Medium errors
-If cdrecord reports medium errors in the form of"Sense Key: ... Medium Error, Segment ...", then the mediumis not empty. If you use CD-RW, then try to switch fromblank=fast to the more reliable blank=all. If you use CD-Ronly, then make sure the CD-R has never seen a CD-writer beforeor try out discs from another manufacturer.
-
-!!5.6 Newly written CDs are not readable on some players.
-
-
-
-Some people reported problems with playing their self-written CDs. Very
-old audio players or car devices can have problems with CD-Rs, although
-this is extremly rare. Quite frequent are problems with CD-RWs, because
-they don't reflect the laserlight as good as CD-Rs and factory-pressed
-"silver" discs.
-
-
-
-
-
-
-
-!!5.7 My scanner stopped working after I loaded the ide-scsi module
-
-
-
-
-
-
-By inserting the SCSI-hostadaptor emulation, the naming of SCSI devices
-changes. If your scanner was /dev/sg0 before, it might be /dev/sg1 or
-/dev/sg2 now. Prominent kernel developers did not think this is completely
-braindead and denied solutions like devfs in the past. But that is another
-story, the first thing you should try is to set the link /dev/scanner to
-point to the actual generic SCSI device. Examples:
-
-
-
-
-
-cd /dev
-ls -l scanner # shows current setting
-ln -sf sg2 scanner
-# test the scanner
-ln -sf sg1 scanner
-# test the scanner
-# and so on
-
-
-
-
-Application developers should carefully think about support for this
-dangerous and error prone naming scheme. Please consider at least
-to use intermediate solutions like the SCSI coordinates used by
-cdrecord.

-Many thanks go to the readers of this HOWTO, who contributed actively to
-its contents. As I don't had access to a CD-writer myself for several
-years, reports about real live setups and experience have always been of
-great value to me.
