I haven't tried that, but I will. If I can determine that this solves
the problem I'll report back to the list.
Thanks!

Have you tried to use the command "mt -f /dev/st0 erase" ? I think
this will ensure that all data of the tape has been erased, including
the eof marks.

Probably not. I have had the same experience with brand new tapes
and a cleaned
tape drive. See thread: When is a tape "Full"?).
My last hypothesis is that it is due to using h/w compression.
After I've
changed back to s/w compression I have not seen this phenomenon.
When that said,
my tape device is DSS-4 from Seagate (Certance) and no tape
changer, sp it could
very well be a different case with same symptoms.
