Gosh. That looks like a bug in Windows. I'm sorry to say that, but
you'll be out of luck as far as Cygwin is concerned with this
extraordinary weird tape ID. Cygwin only supports tapes from tape0 up
to tape127. That should be really enough, who on earth has more than
128 tape drives connected to a single machine!

It's supposed to be, though right at the moment I haven't installed
a 2K8 R2 test system, just a W7 x64 system. I'll check that again
in the next couple of days, but the tape ID you have on your system is
not ok. I'd suggest to deinstall the driver, switch off the machine
and reboot. Maybe the next time the tape drive gets a more sensible
ID. If it sticks to this weird ID, I'd file an SRQ at Microsoft.
