That is really sad. Oh well, it was worth a try.
As for the question on how to verity it. If you just hook it up to an 
RSX system, mount it foreign, and do a "FLX <tape>:[*,*]/DO/DI", and 
you'll either see something sane, or something crazy...

No need. The PDP-11 C tape is a BRU tape image. My tool can repair it if 
it is broken. In addition, I already have a good copy of that tape.
