Hi --
I'm trying to get a good tapetype definition
Below is what I get. Can it be possible to have a filemark At 0 kbytes?
Yes, it could be very well. Some tapes use a small gap between two files to mark the boundary between them. It could just as well be implemented with some out-of-bound data that does not take any space. Amtapetype tries to measure it, but could not detect a significant difference.
This is a LTO Utrium 1 tape drive with "intelligent compression" I can't seem to turn compression off

Seems very reasonable to what should be expected.
