-!! 1. Introduction
-
-
-The Iomega Jaz drive is a removable-media disk drive whose disks have a
-capacity of 1 or 2 Gigabytes. Unlike the Zip drive, the Jaz is only
-available as a SCSI device (internal or external), so a SCSI interface card
-and driver are required to use these drives.
-

-
-!!2. Jaz Hardware
-
-!!2.1 The Jaz Drives
-
-
-
-Jaz drives are SCSI devices and are available as an external drive
-with a 50-pin SCSI-2 self-terminating interface or an internal 3-1/2
-format drive with a 50-pin header interface.
-
-
-Both the internal and external devices are available in either
-1 or 2 Gigabyte capacity, so there are four different Jaz drives
-available.
-
-!!2.2 The Jaz "Disks"
-
-
-
-Jaz disks are a cartridge-style removable media containing a stack
-of three 3.5" platters. From here out, I'll be using the terms
-"cartridge" and "disk" interchangeably to mean the Jaz media.
-
-
-The 1Gb and 2Gb cartridges appear similar, but there is actually a
-subtle difference in their shape which prevents a 2Gb cartridge from
-being fully inserted into a 1Gb drive. Obviously, this means that
-you can't use a 2Gb cartridge in a 1Gb drive.
-
-
-The 2-Gb capacity Jaz drives can read, write, and format both 2-Gb
-and 1-Gb Jaz cartridges.
-
-!!2.3 The Jaz Jet Host Adapter
-
-
-
-Iomega markets a SCSI host adapter under the name Jaz Jet. However,
-there are at least two different SCSI chipsets that are used. For this
-reason, the Jaz Jet isn't necessarily the best SCSI adapter to buy if
-you need one for your Jaz drive. You're better off getting a card that
-you ''know'' your Linux distribution will support (see the next section).
-
-
-
-
-
-One of the Jaz Jet cards is based on the Adaptec 7800 family of adapters.
-Linux 2.0 supports this adapter with the aic7xxx driver. This driver is built
-into most of the standard 2.x SCSI-capable kernels supplied with most Linux
-distributions.
-
-
-The other adapter is based on the Advanced Systems chipset. At boot
-time the board gives a message like:
-
-
-Jaz Jet PCI SCSI adapter Copyright Advanced Systems 1996
-
-
-Depending on your Linux distribution, you may need to build a custom
-kernel (with the CONFIG_SCSI_ADVANSYS variable set) to use this adapter.
-
-
-Personally, I don't like surprises, so if I were going to buy an adapter
-card, I would get a name-brand card with a 50-pin connector, so that I knew
-that what I was getting was supported.
-
-!!2.4 Other SCSI Host Adapters
-
-
-
-If you're using an Ultra-Wide SCSI card with a 68-pin connector, you'll
-need to get an adapter or another cable. The adapters do indeed work just
-fine with the Jaz drive, but can be rather pricey, so if you're buying a
-SCSI card primarily for the purpose of connecting the Jaz drive, you're
-better off picking up a card with a 50pin connector on it.
-
-
-If you're looking for a suggestion, I like the Adaptec AHA-2930U - it's
-cheap, it's fast, and the Jaz drive just plugs right in using the supplied
-cable with no adapter hassles. Unfortunately, support for this card is
-fairly new, so unless you have a fairly new Linux distribution (2.2.x
-kernel), it probably isn't supported. There are patches to the aic7xxx
-driver for 2..36 kernels that support this card, however. The AHA-2940U
-is an excellent choice as well, and it has been supported for a lot longer,
-it's just more expensive.
-
-!!2.5 Kernel Driver Issues
-
-
-
-As always, be sure that your Linux distribution supports a particular card
-EXPLICITLY before making a purchase. Many manufacturers, like Adaptec, have
-cards with numbers and letters ''similar'' to each other that are
-actually ''completely different chipsets'', and therefore use
-''completely different drivers''.
-
-
-Configuring the Linux kernel for a SCSI card is the subject of a complete
-document in itself, so I won't go into that here.
-
-
-Info on rebuilding the kernel should be found in /usr/src/linux/README,
-or in /usr/src/linux/Documentation/ directory for the 2.x kernels.
-If these files don't exist, make sure that you have installed the kernel
-package source for your distribution.

-
-!!3. Identifying the Jaz Drive
-
-!!3.1 During Power-On Test
-
-
-
-With a SCSI controller installed, when the machine is powered up or reset
-the SCSI controller will scan the SCSI bus looking for attached devices
-before booting the operating system.
-
-
-If your SCSI card is correctly installed, and your Jaz drive is attached
-and powered on, you should see the drive listed as something like "Iomega
-Jaz 1GB" or "Iomega Jaz 2GB" during this time.
-
-
-If the drive doesn't show up, there's no sense booting Linux. Power down
-the PC and Jaz drive, and check everything again. In particular, unplug the
-cables and make sure none of the the pins are bent, then replug them and
-ensure they are completely seated against the connector. If you have
-multiple SCSI devices, make sure they all have different ID numbers, and
-that the last device in the SCSI chain is terminated.
-
-
-When the drive shows up in the power-on test, you're half way home.
-
-!!3.2 During Boot
-
-
-
-When Linux boots the SCSI driver should display information about your
-SCSI adapter and what devices are attached to the SCSI bus.
-
-
-Boot messages will vary depending on your driver and adapter, and are logged
-to the /var/log/messages (or /var/adm/messages) file as well as appearing on
-the screen during boot. You can also 'replay' the messages since your last
-boot from the command prompt with the dmesg command.
-
-
-Here's the kernel booting output from a 2..36 kernel with an
-Adaptec 2940 controller (using the aic7xxx driver):
-
-
-
-
-(scsi0) <Adaptec AHA-2940A Ultra SCSI host adapter> found at PCI 14/
-(scsi0) Narrow Channel, SCSI ID=7, 3/255 SCBs
-(scsi0) Warning - detected auto-termination
-(scsi0) Please verify driver detected settings are correct.
-(scsi0) If not, then please properly set the device termination
-(scsi0) in the Adaptec SCSI BIOS by hitting CTRL-A when prompted
-(scsi0) during machine bootup.

-scsi : 1 host.
-Vendor: iomega Model: jaz 2GB Rev: E.17
-Type: Direct-Access ANSI SCSI revision: 02
-Detected scsi removable disk sda at scsi0, channel , id 4, lun
-scsi : detected 1 SCSI disks total.
-(scsi0::4:) Synchronous at 10.0 Mbyte/sec, offset 15.
-sda : READ CAPACITY failed.
-sda : status = 1, message = 00, host = , driver = 28
-sda : extended sense code = 2
-sda : block size assumed to be 512 bytes, disk size 1GB.
-
-
-
-If something resembling these lines doesn't appear, then your kernel is
-probably not configured correctly (or you picked the wrong pre-built
-kernel).
-
-
-If the "scsi0 :" line does not appear, then you have not configured your
-driver correctly. Some drivers will give you a hint about what is wrong.
-If a drive name is not assigned, you probably forgot to include SCSI disk
-support when you built the kernel.
-
-
-Note the READ CAPACITY failed. Most SCSI drivers (like this one)
-will detect that the drive is a removable media type, and not get all
-flustered when it can't read the partition table. However, some SCSI cards
-aren't as graceful. If your PC hangs during boot, try booting with
-a cartridge in the drive.
-
-
-Check the README files in /usr/src/linux/drivers/scsi and the Kernel
-HOWTO for other debugging hints.
-
-!!3.3 Device Name
-
-
-
-In the log output in the previous section note the raw SCSI device name,
-which in this case is "sda", the full name being /dev/sda. If the Jaz drive
-is the only SCSI disk on your system, it will typically be /dev/sda. If
-your primary hard drive is SCSI, or you have a SCSI CD-ROM drive, it could
-be sdb, sdc, etc.
-
-
-Whatever the drive name is, you will need this name to access the drive,
-as explained in later sections.
-----
-
-!!4. Using a Jaz Disk
-
-!!4.1 DOS Formatted Disks
-
-
-
-Jaz disks come pre-formatted from Iomega with a single partition using
-the DOS FAT16 file system. The single partition is usually the 4th disk
-partition (for Mac compatibility - the Mac requires data to be on the 4th
-partition, but the PC doesn't care which partition data is on).
-
-
-Linux is perfectly happy reading and writing a FAT16 file system, so you
-can use the disk as is. In order to use the disk, you need to mount it, so
-the first thing you need to do is create a mount point. For this document,
-we'll mount all our DOS Jaz drives under /dos_jaz, so let's create
-that mount point (you'll need to be root for most of this stuff). You'll
-only need to do this once:
-
-
-mkdir /dos_jaz
-
-
-In a previous section, I mentioned you'd need to remember the Jaz drive's
-raw SCSI device name. You need that now. If your drive is
-/dev/sda then all these examples will work for you. If not, you'll
-need to replace "sda" with the device ID of your Jaz drive. Since you need
-to issue these commands as root, you'll want to be sure you have the correct
-names.
-
-
-If you have a 2.0 kernel, or have added VFAT support, you can mount the
-Jaz disk this way, and have long filenames under FAT16:
-
-
-
-
-
-mount -t vfat /dev/sda4 /dos_jaz
-
-
-Note that although VFAT allows you to use long filenames, those filenames
-are still case ''in''-sensitive, and although 'ls' lists permissions,
-you can't actually change permissions on any of the files.
-
-
-If the "vfat" format is not recognized by the mount command, then you'll
-use this command to mount the Jaz disk:
-
-
-mount -t msdos /dev/sda4 /dos_jaz
-
-
-Once you have issued either of the mount commands, files from the disk
-will appear under the /dos_jaz directory. While the disk is
-mounted, you will not be able to eject it.
-
-
-When you are done with the disk, you can unmount it with the command:
-
-
-umount /dos_jaz
-
-
-Once unmounted, you can press the button on the front of the drive to
-eject the cartridge.
-
-!!4.2 Repartitioned DOS Jaz Disks
-
-
-
-Since a Jaz disk is simply a disk, it can be repartitioned and reformatted
-like a fixed disk. If this is done, you need to know which partition numbers
-were used during repartitioning to be able to mount the disk.
-
-
-For instance, if the partition table was wiped, and a single new partition
-was created as the first partition, the two mount commands from the previous
-section would be:
-
-
-mount -t vfat /dev/sda1 /dos_jaz
-
-
-and
-
-
-mount -t msdos /dev/sda1 /dos_jaz
-
-!!4.3 Linux-Native Jaz Disks
-
-
-
-Linux-Native Jaz disks allow files to be stored with standard Unix
-permissions and case-sensitive filenames. The only drawback to Linux-Native
-disks is that they can no longer be used on DOS/Windows machines.
-
-
-A Jaz disk looks the same as a hard drive to Linux, so for those of you
-familiar with the Linux disk management tools, none of the following will be
-a surprise.
-
-
-
-
-
-If you want to erase a Jaz disk and make a Linux native file system on
-it, you use fdisk on the entire disk. Please be very careful using fdisk,
-especially if you have a SCSI hard drive - we wouldn't want to have any
-"accidents". :-) In particular, make sure you are operating on the correct
-device before making changes. In most cases, you'll use:
-
-
-fdisk /dev/sda
-
-
-and delete the existing partitions (with the d command). Then create a new
-partition with the n command, make it primary partition number 1 (using all
-the cylinders), use w to write the partition table to disk, and quit with
-q.
-
-
-Once the partition has been created, format it with:
-
-
-mke2fs /dev/sda1
-
-
-(The 1 is the number that you gave this partition in fdisk). I prefer to
-create a separate mount point for Linux native Jaz disks, and you'll see why
-a little later when we talk about the fstab. So let's create that
-mount point now, and then mount the disk:
-
-
-mkdir /jaz
-
-
-mount -t ext2 /dev/sda1 /jaz
-
-
-As usual, when the Jaz disk is mounted, it cannot be ejected. When you're
-done using the Jaz disk, you unmount it with:
-
-
-umount /jaz
-
-
-Once unmounted, you can press the button on the front of the drive to
-eject the cartridge.
-
-!!4.4 Checking Linux-Native Jaz Disks
-
-
-
-Like your other disk drives, once a Linux Jaz disk has been mounted and
-unmounted a certain number of times, the system will mark the disk as
-"dirty". When this happens, you'll get a message like:
-
-
-Mounting unchecked filesystem, /dev/sda1. Recommend running e2fsck.
-
-
-Once you see this message, it's a good idea to go ahead and check the disk.
-The disk must be ''unmounted'' in order to check it. Unfortunately, you
-only get the "dirty" message when you mount it, so you can either check the
-disk when you're done using it, or unmount it, check it, then re-mount it.
-Use the following command to check the disk (assuming the partition to be
-checked is the first one):
-
-
-e2fsck /dev/sda1
-
-!!4.5 Using the fstab to Make Things Easier
-
-
-
-Up to now, we've had to be root to mount and unmount the Jaz disks, and
-we've had to type quite a bit to mount the Jaz disks. By adding a couple of
-entries to the file /etc/fstab, we can make using the Jaz drive
-''much'' easier.
-
-!DOS Format Disks
-
-
-If you've got preformatted DOS disks, and you've created the
-/dos_jaz mount point, you can add this line to the file
-/etc/fstab:
-
-
-/dev/sda4 /dos_jaz vfat defaults,user,nosuid,noauto 0
-
-
-With this line in the fstab, ''any user'' can mount and unmount a
-DOS-format Jaz cartridge with the following commands:
-
-
-mount /dos_jaz
-
-
-umount /dos_jaz
-
-
-This is because we have told Linux what the Jaz device ID and media type
-are in the fstab, plus we have given the user option to
-allow any user to mount and unmount the disk. Naturally, if your Jaz drive
-is other than sda, you'll need to change that, and this won't work
-for DOS cartridges that have been repartitioned without another entry in
-the fstab that uses a ''separate'' mount point (e.g. /dos_jaz2).
-
-!Linux Format Disks
-
-
-If you've got Linux formatted disks, and you've created the
-/jaz mount point, you can add this line to the fstab:
-
-
-/dev/sda1 /jaz ext2 defaults,user,exec,nosuid,noauto 0
-
-
-With this line in the fstab, ''any user'' can mount and unmount a
-Linux-format Jaz cartridge with the following commands:
-
-
-mount /jaz
-
-
-umount /jaz
-
-
-Once again, we have told Linux what the Jaz device ID and media type are
-in the fstab, plus we have given the user option to allow
-any user to mount and unmount the disk. Some system administrators may not
-wish to have the exec option present, as there are some security
-risks with letting any user run an executable of unknown origin from the
-drive, but with the nosuid option present, these risks are
-minimal.
-
-!Automatic Mount at Boot Time
-
-
-Both of the fstab examples above have the option noauto
-in them to prevent the disk from being automatically mounted at boot time.
-In general, this is a good idea because if there is no disk in the drive
-when the computer boots, or the drive is powered off, it can cause varying
-amounts of trouble, depending on which SCSI driver you are using.
-
-
-If you're ''sure'' you want to mount the jaz drive at boot time,
-simply remove the noauto option, and make sure the drive is on,
-and a cartridge is inserted before booting. Note that you can only have
-one fstab entry for jaz drive that will auto-mount, or you may encounter
-the same problems as if there was no cartridge in the drive.
-
-!!4.6 The Jaz "tools" Disk
-
-
-
-With some Jaz drives, the software to run the drive is supplied on a
-Jaz cartridge instead of on CD-ROM. The "problem" with these disks is that
-software-controlled write protection is enabled on the disk, so that the user
-can't wipe the disk until after the tools are installed at least once.
-
-
-There are several ways you can reclaim the Jaz tools disk:
-
-
-*Install the tools on a DOS/Windows computer.
-*
-
-*Use a DOS/Windows computer with the Jaz tools already installed to
-remove the password protection.
-*
-
-*Use one of the Linux Utilities mentioned in a later section to remove
-the password protection.
-*
-
-
-
-If you have access to one of the password protection removal programs, all
-you need is the password that Iomega uses, and it is:
-
-
-APlaceForYourStuff
-
-
-Note that capitalization is important.

-
-!!5. Linux Utilities for Jaz Drives
-
-!!5.1 jaztool
-
-
-
-jaztool is a Linux utility written by Bob Willmot to support some of
-the Jaz drive's features (including software controlled ejection and write
-protection). I like jaztool because its commands can be embedded in alias
-commands and scripts. It's also easy to compile and install.
-
-
-The original source code for jaztool can be found at
-http://www.willmot.com/jaztool/ and is also mirrored at my site at
-http://www.ultranet.com/~hsd/HOWTO/index.shtml#jaztool
-
-Note that to use jaztool with a 2Gb Jaz drive, you must change ONE line
-of code. Change line 188 from this:
-
-
-return(!strncasecmp(id,"IOMEGA JAZ 1GB",15));
-
-
-to this:
-
-
-return(!strncasecmp(id,"IOMEGA JAZ",11));
-
-
-__NOTE:__ There are __two spaces__ between IOMEGA and JAZ in
-the previous two lines of code. SGML (or maybe just HTML) apparently
-removes the extra whitespace.
-
-
-After building jaztool and installing it, it must be suid root, or run
-as root, or it won't work.
-
-
-I use jaztool regularly, so if you have a question about it, I would be
-happy to try and answer it.
-
-!Ejecting a Cartridge
-
-
-Use the following command to eject a cartridge:
-
-
-jaztool /dev/sda eject
-
-
-This might seem like a lot to type, but it's easy to make a slick
-alias like this:
-
-
-alias jazej 'umount /jaz; jaztool /dev/sda eject'
-
-!Password Protection
-
-
-There are two password protection modes on a Jaz, and both are controlled
-through software. One is Write Protected and the other is Read/Write
-Protected. jaztool will allow you to unlock a Write Protected disk, but
-under Linux, a device that cannot be read cannot be mounted, so Read/Write
-Protected is not supported.
-
-
-If the cartridge is Write Protected (such as a Jaz Tools disk), use the
-following command to unlock it (the disk must not be mounted):
-
-
-jaztool /dev/sda rw
-
-
-jaztool prompts for a password, and if the password is correct, the disk
-is unlocked and ejected. This must be done to cause the SCSI driver to
-pick up the new mode when the cartridge is re-inserted.
-
-
-To make the disk Write Protected again, use the following command:
-
-
-jaztool /dev/sda ro
-
-
-jaztool again prompts for a password, and the disk is locked and
-ejected.
-
-
-Note that jaztool doesn't support the "Unprotect until Eject" feature
-found in the Windows world. If you remove the password protection, it
-is removed until you put it back on.
-
-!!5.2 jaZip
-
-
-
-If you'd prefer a nice, slick, graphical user interface to control
-your Jaz (and Zip!) drive, there's the jaZip tool. Check it out at:
-http://www.scripps.edu/~jsmith/jazip/
-
-I haven't used jaZip myself, so please contact the author directly with
-questions on jaZip. Contact information is on the website listed above.

-If the Jaz drive co-exists with other SCSI harddrives, most BIOSes will
-want to boot the disk that has the lowest SCSI Id. The Jaz drive can be
-set to SCSI Ids -6, and typically come out of the box set to SCSI Id 5.
-Some BIOSes detect and skip removable devices like the Jaz. If your
-BIOS will boot from a Jaz, you can set your main SCSI harddrive to SCSI
-Id 1, then you can change the Jaz from SCSI Id 5 to 0 when you want to
-boot from the Jaz.
-
-
-More typically, the Jaz drive co-exists with an IDE harddrive. Nearly
-every BIOS will want to boot the first IDE harddrive. Some BIOSes will
-allow you change a setting in the BIOS setup to boot from a SCSI device
-first. Others may require you to disable the IDE drives in the BIOS
-setup. Still others may require detaching the IDE drives physically or
-disabling the IDE interface.

-!!6.2 Installing Linux on a Jaz Cartridge
-
-
-
-Although running Linux from a Jaz cartridge is ''much'' slower than
-running from a harddrive, the Jaz drive makes an excellent ERD (Emergency
-Repair Disk). It's also fun to be able to just pop in some new Linux system
-or to try Linux on someone else's Jaz-equipped machine.
-
-
-By far the easiest way to install Linux on the Jaz cartridge is simply to
-follow the install procedure for your favorite distribution with the Jaz
-drive being the only drive on the system. I've done this with !RedHat 5.2,
-and it works perfectly. If you're not completely comfortable with doing
-weird, wild stuff with LILO, it's the only way to go.
-
-
-If you want to do an "install" from your running system, you can
-often succeed in "building" a bootable system on a Jaz cartridge.
-
-
-
-
-
-*Partition the drive and make the filesystems. You probably need to
-have a swap partition, too, but if you have lots of RAM then maybe not.
-Mount the new root as /jaz and any additional partitions within that
-directory as appropriate.
-*
-
-*Copy all the files into place. Be sure all the /dev
-files are copied. Be sure all permissions, ownership and group ids
-are retained.
-*
-
-*Modify the files on the Jaz cartridge to suit the
-circumstances of booting from it. In particular be sure to change
-/jaz/etc/fstab to mount the Jaz cartridge partition(s) as
-appropriate. Also change /jaz/etc/lilo.conf to match as well.
-*
-
-*There are two alternatives for installing the LILO boot loader:
-
-
-**Make a kernel image floppy and use rdev to make it
-mount the Jaz cartridge as root. Boot from the floppy when ready
-the first time then run LILO to make the Jaz MBR bootable.
-**
-
-**You can run LILO from your non-Jaz root running system to
-install the bootable MBR on the Jaz cartridge
. For more information
-on this option, check out
-Alessandro Rubini's LILO mini-HOWTO
