I'm guessing that the only thing wrong with the drive was the sucked in
leader. This is a *common* problem with DLT drives (well, it is for us
around here, but considering how many we have).

What happens when you apply power? There really aren't any tests you can
run outside a machine that I'm aware of, plus I'm only familiar with DLT4000
and DLT7000 drive (since you can't really count TK50, TZ30, and TK70
drives).

Maybe. The TK85 bridgeboard should convert a TF85 into a TZ85 (are the SCSI
drives actually called TZ, or TK?). On the DLT4000/7000 drives I believe
it's just the board on the back that defines if they're SCSI-Diff or
SCSI-SE.

Just go ahead and hook it up.
