I've always had bad luck with CDBakeoven. Things have worked much better
(for me at least) with K3b and XCDRoast.

That having been said, before you can get any atapi CD drive to work
with cdrecord, you need to enable scsi emulation. It's a (minor) pain,
and I've heard that this won't be necessary with the 2.6 kernel, but for
the 2.4.x kernel it's required. Look at the output of "cdrecord
-scanbus" to see if you have scsi emulation already enabled:

bob@sonic:~> cdrecord -scanbus

Schilling
Linux sg driver version: 3.1.25

        0,7,0 7) *

If that didn't work, see below...

I don't know if you're booting with lilo or grub, but you need to pass
an option similar to this to the kernel in /etc/lilo.conf or
/boot/grub/menu.lst:

  hdc=scsi hdd=scsi

In the above case, my two CD drives are /dev/hdc and /dev/hdd - it won't
work for you if your drive(s) are configured differently. One good way
to find out what you've got is to use the eject command, for example:

  eject /dev/hdc

If the drive ejects, you know that one is /dev/hdc.

You may also need to edit file /etc/fstab (backup the old one first).
Something like this:

  /dev/cdrom /cdrom iso9660 defaults,ro,user,noexec,noauto 0 0
  /dev/cdrom1 /cdrom1 iso9660 defaults,ro,user,noexec,noauto 0 0

Make sure you do have the directories /cdrom and /cdrom1 - create them
if you don't.

Finally, you need symbolic links for the above devices. Delete the
existing ones, and create new ones:

  rm /dev/cdrom
  rm /dev/cdrom1
  ln -s /dev/scd0 /dev/cdrom
  ln -s /dev/scd1 /dev/cdrom1

Check to make sure this worked:

  bob@sonic:~> ls -l /dev/cdrom*
  lrwxrwxrwx 1 root root 9 Dec 21 20:45 /dev/cdrom ->
/dev/scd0
  lrwxrwxrwx 1 root root 9 Dec 21 20:45 /dev/cdrom1 ->
/dev/scd1

That ought to do it. Reboot.

cdrecord -scanbus should report good results now.

Hope that helps. (Also, hope I got all of the above correct - if not,
I'm prepared to be flamed, drawn, and quartered).

regards,
Robert
