Re: SCSI CD, reported by kernel, isn't there.

[Alec Smith <alec@shadowstar.net>]

I have had a very similar problem too... Its almost certainly the 
termination if you can see all your drives listed during boot. (if a drive 
is missing there, you'd want to look for a SCSI ID conflict) If you still 
have problems after termination is 100% correct, it could be a bad SCSI cable.

SCSI is nice once its working. Getting termination right can be a real pain 
if you're just learning how to deal with SCSI systems.
