I would agree that trying the tape drive on
another machine would be the next logical
step.
If you had a scsi hard drive to work with,
especially if it were preformatted and ready
to go after being set up on a different
machine, it should pop right up in Windows,
or be easily detected and then manually mounted
under linux. Then the drive can be torture-tested,
to see if any problems come up.
Even before the OS loads, there should be some
scsi BIOS utility for probing devices and maybe
doing some tests. There might be an option for
low-level formatting and verifying the drive,
which would be a good test.
If those things are not operational, are there
no conflicts reported under the devices tab /
scsi, when you get properties on My Computer
under Win95?
Could it be that you have to set a jumper, to
terminate the card itself? Often the card
is the beginning of the SCSI chain, and since
the first and last device need to be terminated,
there is termination on the card. But sometimes
the card ends up in the middle (like when there
are internal drives and external drives), and
sometimes (check the card's instructions)
you would remove termination from the card.
