Depends on whether the combined length of the three files on the tape is 
shorter, longer, or the same as those overwritten.

	mt -f /dev/nrst0 fsf 3		(skip over the first three files)

If new length == old length, you're now at the beginning of file four,
and you can recover it and five with 'tar'.

If new length < old length, "mt -f /dev/nrst0 fsf 1" again should put
you at the beginning of file four.

If new length > old length, the tape is now positioned somewhere inside
of the old file four.  That one is probably not recoverable, but
"mt -f /dev/nrst0 fsf 1" should put you at the beginning of file five.
