After trying to restore from a Standalone Backup, I
am unable to get to any of the files on the tape.

The Standalone backup will mount ok, but returns with a
		FATAL CONTROLLER ERROR

I've also tried mounting the tape with /BLOCKSIZE=8192 and tried
to COPY the tape to a disk on another system.  Same result.

Finally, I tried using a utility called TDUMP from Emory University
which uses a blocksize of 32767 with the same result.

Question: Does anyone know if there's a way to salvage the TK50 tape?
*********

I've thought about trying to start a `new' backup to the tape and 
aborting.  This worked one time when I accidently used the /REWIND
qualifier when trying to append a saveset.  The tape would
write the new saveset, hit the end too soon and ask if I
wanted to continue. Continuing, allowed me to see the files from
the original saveset as if nothing had happened.
