Correct, back10 does get some things wrong.  It also puts some data at
the beginning of files which should be part of the file header.  TITO
uses the "*FAILSAFE" magic number which fools back10 to think it's

What problem do you have with my tito tool?  Which tape did you try?
I haven't tested all tapes, so maybe some of them has surprises.
I'm not sure what to do with the file checksum yet.
