The cdrom IS the medium, so if you try to mount it when the drive is
empty, that error message is to be expected.
It's probably easiest to always use the ide-scsi module and link
/dev/scd0 to /dev/cdrom, rather than to switch between ide and scsi
drivers. You should then edit fstab to reflect this (it works for me,
anyway).
