  That mount point is unnecessary since 1.3.3, see Users Guide:
  http://cygwin.com/cygwin-ug-net/using-specialnames.html#AEN590

       ^^^^^^^^^^^^
       unnecessary since /dev/tape is the default device name for
       mt version >= 2.0.

Probably wrong blocksize.  See if the blocksize is set correctly:

$ mt status 2
tape capacity    :  1953251 KB          remaining        :  1953251 KB
current block    :        0             write protected  :       no             datcompression   :       on
min block size   :        1             max block size   :    65536
def block size   :    16384             cur block size   :      512
report setmarks  :       on

Then try using the correct fixed blocksize if you know it:

  mt selblk 5120

Or variable blocksize for reading if you don't know the blocksize
used for writing the tape:

  mt setblk 0
