How to read a tape drive?

[greenpee]

Hi,

I need to read a couple of DDS3 tapes. I know the tapes are backups of a unix or linux machine. The tape drive I am using is in a windows NT box and device name is \\.\Tape0. I installed Cygwin to read the tapes.
I got the following errors while try to rewind or read the tape
#mt -f \\.\Tape0 rewind
mt: \.Tape0: No such file or directory
# tar -tvf \\.Tape0
tar: \\.Tape0: Cannot open: No such file or directory
tar: Error is not recoverable: exiting now
Could someone help me out.

Thanks a lot
