That was sd0, not scd0; sd are the SCSI disk devices, SCD are the
CD-ROM devices.
So, that wouldn't work, as you noted. :)
The best way to work out where it is would be to look in
/proc/scsi/scsi, where you would see which disk device the FDD was
assigned.
At that point it should be accessible. From your cdrecord scan it looks
like 'sd0' would be the right place, given you have one SCSI CD and one
SCSI disk device connected.
