Is it detected as /dev/scd0?
On my system, it's /dev/sr0
Look at bootup messages (dmesg command or /var/log/messages):
Detected scsi CD-ROM sr0 at scsi0, channel 0, id 4, lun 0
(scsi0:0:4:0) Synchronous at 8.0 Mbyte/sec, offset 15.
Vendor: IOMEGA Model: ZIP 100 Rev: D.09
Type: Direct-Access ANSI SCSI revision: 02
Detected scsi CD-ROM sr1 at scsi1, channel 0, id 0, lun 0
Vendor: COMPAQ Model: PD-1 LF-1195C Rev: A110
Type: Optical Device ANSI SCSI revision: 02

That's another problem altogether. I don't know...
