Well, I had a look into the straces and it's really weird.  Opening
the tape device works fine, but calling any of the Win32 tape functions
(for instance GetTapeParameter) results in a Win32 error 1, "Incorrect
function".  I can't change anything in Cygwin to circumvent this and
I can't get any further information.  It's just this, no Win32 tape
access function is working.

This is really unexpected.  I'm wondering if something's broken in your
configuration.  Maybe the driver is broken?  Perhaps you should try to
reinstall it or something.


Sorry if that's no help,
Corinna
