The patch seems to have helped things - thanks! Now I can actually
successfully compare a tape I made before. However, I do still see
some errors - first, I got I/O error message at the beginning of the
compare. Then, a "mt -f /dev/nht0 status" call took a very long time
to complete, and when it returned it didn't know what block it was on.
No new messages appeared on the console, but I think the mt is
responsible for the later error messages - I'm not sure which ones
exactly, though. Anyway, I've included the log entries at the end of
this message.
I'll try to play with the drive some more today - anything I should be
looking for?
