These two lines are actually a little strange.  I would have expected
that the second pass wrote a little bit less then the first pass (and
the difference is the space taken up by the additional filemarks).

Actually..... on my DAT drives I get the same thing. Reliably. Multiple (new) tapes, multiple drives. I think maybe a bug in the tapetype program of some nature. I've only ever run the tests without compression personally.
