Zapped tar tapes
You can usually get the rest of the stuff off of a tar tape even if
there is a bad spot.  Have you tried repeated tar's after the read
error.   What will usually happen is that it will get resynchronized
after a short time.  If that fails, and you are desparate, you could
use a number of cp's to copy sections of the tape into files and then
edit the files in some fashion.  (Assuming that you have got source
files in the tar and you have an editor capable of editing binary
data, such as Emacs by Gosling, (you could use Mlisp for the hacking)).

I once wrote a program to rebuild VMS tapes that had been zapped, but
that wouldn't help you in this case.
