+Standard discs hold 650[MB] or there abouts. The normal filesystem used on a [CDROM] data track is [ISO]9660.
+There are two competing standards to allow longer filenames and a few other things [ISO]9660 does not provide. The earlier one, originating from the [Unix] environment, is called Rock Ridge. The other one, made up my MicrosoftCorporation, is called Joliet. (Note that some characters that are valid on [Unix] FileSystems are not allowed on Joliet discs.)
-Standard
discs hold 650MB
or there abouts
. The normal filesystem used on
a data CDROM is
[ISO
]-9660
, although most discs also use MicrosoftCorporation's Joliet extensions that allow some things like long filenames (although some characters that
are valid on unix filesystems are not allowed)
. Another such extension is
called Rock Ridge
.
+For reading audio
discs or writing CDs, you need access to the [CDROM] drive raw device
. Under
a [Linux
] OperatingSystem
, these
are called __/dev/hd''x''__ for [IDE] drives and __/dev/scd''n''__ for [SCSI] drives
. Under [FreeBSD] 5 and later, they're
called __/dev/acd''n''__ for [IDE] drives and ''??? (AddToMe)'' for [SCSI] drives
.
-On a [Linux] OperatingSystem, your [IDE] drives (both CDROM or HardDisk) will be available
-as raw devices in /dev/hda (for primary master), /dev/hdb (for primary slave),
-/dev/hdc (secondary master), or /dev/hdd (secondary slave).
-[SCSI
] drives will be /dev/scd<i> where <i> is a number starting from .
-
-You only need to worry about raw access for reading audio disks or writing CDs. For accessing data, the disc will be mounted.
-
-Freebsd (5 and later) has raw device files available for IDE CDROMs as /dev/acd0, /dev/acd1, etc.
