[comp.os.vms] Recovering files from after TK50 Eof?

manager@Earth1.GPS.Caltech.EDU (01/19/88)

 
Summary: I need to recover data from past the End-of-Volume 
         (double EOF) marker on a TK50.  A user INITialized the
         tape and wrote a short save-set at the beginning of the
         tape and I need to recover the data near the end of the
         tape.
 
I have tried various programs that people around Caltech have 
given me, all with no success. The symptom is that the TK50
will get confused and rewind the tape (all by itself, let it be
noted!) whenever I try to do anything past the end of volume.
I *know* this is the right tape, by the way.  And on the few programs
that the TK50 doesn't rewind the tape, I get continual PARITY-READ
errors from the controller.
 
Any help would be greatly appreciated. Two full years of a graduate
student's work are on this tape.
