I think you are.

/dev/st0 is a virtual device in Cygwin that corresponds to \device\tape0
in Windows NT+.  You are trying to remake this association via the mount
table.  Why?

What is that for?  /dev/st1 is a Cygwin virtual device that corresponds to
\device\tape1 in Windows NT+.  You are trying to reassociate that via
mount.  You must not have understood the Users Guide section quoted above
at all.

Try simply ln -s /dev/st0 /dev/tape

You have really confused things with the mounts.

I assume you properly quoted those '\' or used a cmd shell?  Anyway, don't
expect POSIX device behavior if you use a Windows device path.

Don't use mount.
