Hi Dylan,

If this is 2.6 we're talking about, do:

   modprobe -a ide_cd

If it says "module not found", look in your .config file to see if the
module was built into the kernel.

Also, ide_cd and ide-scsi are mutually orthogonal.  Make sure that ide-scsi
is NOT enabled (or that the module is NOT loaded).

Also, remove any arguments like:


that you may be passing to the kernel via lilo or grub.


PS- Ignore cdrecord -scanbus.  It's useless now.  You access the drive using
the IDE name, as in:

   cdrecord dev=/dev/hdX etc etc etc...
