Problem: 
   TK50 that has had the front of a tar file overwritten by another
   much shorter one. Can I get at any of the data of the original file
   on the tape?

   I am willing to consider manually winding on the TK50 If I have to.
   MT seems unable to get past the EOF and the first partial block on
   the tape.

   Any ideas or should I give up?

   Thanks.
