ide-tape unusual/failing behavior
I have what appears to be a working Onstream DI30 tape unit
installed. This unit runs just fine when I boot into Win
2000.

Still, it doesn't actually seem to be working. mt gives
failures, and tar can't write:
# mt -f /dev/ht0 rewind
mt: /dev/ht0: Input/output error
# mt -f /dev/hdc rewind
mt: /dev/hdc is not a character special file
# tar -cf /dev/hdc somefile
# tail /var/log/kern.log

I'm not sure how to move forward from here to get this to work,
and I can't find any documentation, other than "it should just
work".
Any suggestions?
