This is the information for your SCSI chain.  It shows a 2 GB Quantum
on ID 0, a TEAC CD-ROM drive on ID 3, and an IBM 4 GB drive on ID 6.
No tape.

No, this is your first SCSI disk (/dev/sd0*).  Look at the beginning
of the line.

So why isn't the tape drive being found?  This is typically a cabling
problem, or possibly you have the ID set incorrectly.  Possibly, also,
you have another device which is conflicting with it, in which case
both of them won't show.
