- You're almost certainly out of luck. When you reinitialized the tape, you very
- probably corrupted the first block of data. When the drive tries to read the
- tape, it will probably get a parity error. You can't skip past a parity error
- on a TK50.
-
- On the off chance you DON'T get a parity error, you can use something like DUMP
- to skip past the double-eof, then use BACKUP to restore from the rest of the
- savesets on the tape.
