speaking of tape, it got this HP1533a scci tape that I used twice, in over
4 years.  Recently I tried it again and it rewind the tape to the begin
and then fails and ejects the tape.  When I pull out the tape, there is
like 1 inch of the tape hanging lose outside the cartridge.

The tape drive  is in a server that is on 24/7.  It was new when I bought
it, and never got a chance to really use it.

Anyone seen this kind or problem?  oh , it's a DDS2 type.
