The output is strange. Was a media in the drive? Why does NT
report a capacity of 0 and remaining 0?

Please insert a media into the drive and send me the output
of

	mt -f /dev/ct status 3

You get this `permission denied' when you try to read a tape,
that is written with another blocking factor than the Windows
tape driver is set to. Currently cygwin has no automatical
recognition for this. You must(!) know the blocking (U*Xes
typically uses 5K blocking on tape devices) and you can set
it with my `mt' command.

What's that? Above you mentioned that you have successfully
mounted???
