I seem to recall reading somewhere (I thought it was INFO-VAX, but can't  find
the  posting)  about an upgrade to TK50 drives that fixes the problem where if
you try to perform an operation on the tape while there's not actually a  tape
ready  in  the drive, you lose the drive at least until the system is rebooted
(only shutting off power to the system for a substantial  length  of  time  is
guaranteed  to make the drive usable again).  I know that the problem has been
fixed in more recent drives (the most recent VAXstation to arrive here doesn't
have the problem).  Is there in fact an upgrade to the older drives that fixes
the problem?  If so, what is the upgrade number?  Thanks.
