	This was a very dumb assumption!!!!!!!

	The following may be a valid enhancement to the script as it
actually reads the tape during the verify pass rather than just passing
over looking for lack of signal.

	I have added these two sections to the old Tbackup.sh and am
using it.  Edit in the two cammands above and remove the old cammand
from the verify pass and move the result to 'Tbackup.sh".
