Tape support is in Cygwin, transparent to applications.  tar or cpio
don't know anything about it.  The usual problem when accessing a tape
fails is the fact that the blocksize of the OS tape driver is not set to
the blocksize on the tape.  Either you know the blocksize on the tape
is, say, 120 bytes, in which case you set the OS tape driver to 120
bytes:

  $ mt setblk 120

or you don't know the block size on the tape in which case you set the
OS tape driver to variable block size:

  $ mt setblk 0
