I've got a HP35480A and I've been having nothing but trouble
since I purchased it (had success with a conner DAT though :).
Basically, I can't succesfully read or write to or from a DAT -
between I/O errors and SCSI bus timeouts, nothing works. Trying
to view or extract a tar on a DAT I'd made earlier, sends the
drive off (presumably reading) for a while. Despite using the
'v' option with tar, I get no feedback, and the drive just sits
there, reading a bit, going 'clunk', sometimes rewinding a
little, then reading again - and so on. Eventually, I get some
sort of SCSI timeout. <sigh>

The conner drive works fine... (and the DAT's themselves are
fine)

So: does your drive actually make any motions when you send
either mt or tar commands to it? If not, then it could be
perhaps a SCSI configuration error. If so, then it could be a
'HP error' like I'm getting :/

And as a side-note, could anyone recommend what SCSI settings I
should be using with such a tape drive? I haven't been able to
find out much on the web, and I'm looking for recommendations
for such values as 'Command Queueing' and 'Synchronous
Transfers' - what do tape drives usualy take for SCSI settings?

Well, hope you have more luck than me :)

Cheers,
