IDE : SCSI : ATAPI
Access to hardware is required - SCSI command
set required
IDE drives need hd(drive letter)=ide-scsi
Lilo example : append=”hdc=ide-scsi”
May have to recompile kernal with
–
Block devices -> Include IDE/ATAPI CDROM support = n
–
Block devices -> SCSI emulation support = y
–
Both SCSI support and SCSI CDROM support will be enabled. (y) not (M).
Iso9660 File system
Only 8 levels of sub-directories allowed.
Maximum length for filenames: 32 characters
640 MB capacity
Directory structure similar to DOS
Sector size of 2048 bytes
Permits only capital letters, digits and underscores in a file or
directory name or extension
Read-only
Audio vs Data CD's
Audio CDs use all 2352 bytes per block for sound samples.
Data CD-ROMs use 2048 bytes per block, with most of the rest
going to ECC (Error Correcting Code) data
Both have two lower levels of correction through CIRC (CrossInterleaved Reed-Solomon Code) encoding
Extensions
RockRidge
Extension to allow longer filenames
Deeper directory hierarchy for the ISO-9660 file system
Under Linux, known properties of files like owner, group,
permissions, symbolic links appear ("feels like a Unix file system").
These extensions are not displayed under DOS or the Windowsfamily of operating systems.
Extensions
El Torito
Used to produce bootable CD-ROMs.
The BIOS of your PC must support it.
The first 1.44 or 2.88 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.
While booting from this virtual floppy, your original drive A:
(/dev/fd0) may not be accessible.
Extensions
HFS
Lets a Macintosh read the CD-ROM as if it were an HFS volume (the
native file system for Mac OS).
Extensions
Joliet
Brings long filenames (among other things) to newer Windows (95+)
Use filenames up to 64 characters in length, including spaces.
Records the associated DOS-standard name for each file so that the disc
may be read on DOS systems
Extensions
VCD
Video-CDs can be directly played on DVD-devices.
Each disk contains about one hour of video. As a result most movies
come on two disks.
Highly compressed and does not have the smoothness or color of a
DVD disk.
Copying CD
Dd and Cat
Readcd
Grip
Cdda2wav
Cdparanoia
Copying CD - system
dd
if=/dev/cdrom
|
|
(device to read from)
of=/temp/iso/cd.iso
(file to write image
to)
cat
/dev/scd0
|
|
(device to read from)
/temp/iso/cd.iso
(file to write image
to)
Does not need to be run as sudo or root
Copying CD - readcd
Part of the cdrecord suite
Must be run sudo or root
[root@hickorydale carl]# readcd
0:read 1:veri 2:erase 3:read buffer 4:cache 5:ovtime 6:cap
7:wne 8:floppy 9:verify 10:checkcmds 11:read disk 12:write disk
13:scsireset 14:seektest 15: readda 16: reada 17: c2err
Enter selection: 0 (0 - 20)/<cr>:
Copying Music CD - grip
Audio CD ripper with
point and click interface to
cdparanoia
Copying Music CD
Cdda2wav
cdda2wav -D 0,4,0 -B /tmp/prefix-of-music-files
-D 0,4,0 : set the cdrom or scsi device (as Bus,Id,Lun)
-B path : record each track into a seperate file.
The files will be written out as:
/tmp/prefix-of-music-files_01.inf
/tmp/prefix-of-music-files_01.wav
/tmp/prefix-of-music-files_02.inf ...
Cdparanoia
cdparanoia -vB 1- /temp/wave/
-v
: verbose, uses emoticons to display progress/errors
-B :batch, save each file in seperate file
outputting to /temp/wave/track01.cdda.wav

Making an .iso Image
1. Create directory and import files.
2. Use mkisofs to make iso image.
mkisofs -rJ
-o cd_image private_collection/
'---' '------------'
'---------------------'
|
|
|
(make public & Joliet) (write output to) (take directory as input)
3. Test the image
mount -t iso9660 -o ro,loop=/dev/loop0 cd_image /mnt/iso
- and look around
or
cmp /dev/cdrom cd_image
Writing the CD with Cdrecord
Part of the cdrtools by Jorg Schilling
http://www.fokus.gmd.de/research/cc/glone/employees/joerg.schilling/private/cdrecord.html
cdrecord -vv speed=10 dev=0,0 -eject /home/temp/cd.iso
`--' `----------' `--------' `-----' `---------------------'

(verbose) (max write speed) (device) (when done) (iso image file)
cdrecord --scanbus
