Thanks... I had been working with the RTOS for so long I
forgot that Solaris had tcopy. It isn't a complete solution
but it reads across the error points. It HESITATES there, but
it reads, throws no errors, and claims to have found the
correctly sized 61440 block at the point where dd and my
program fail.

Since the tapes go to 35 GB, which would end up in a single
file, I don't think I can use this as a permanent solution,
but it indicates that the tape is ok.

respectfully
BJ
