Hello, thank you very much for your reply.
I do not think the tapes are broken because it occurs on two different 
machines, there are about 60 films and many of them new.
Moreover there are no errors in the logs of SCSI.

I'm lost, I do not know where to look.
If I boot BTAP, run a test goes as follows:
Got EOF on tape.
Got EOF on tape.
Got EOF on tape.
Got EOF on tape.
.
.
.


I do not know if this can also help in something.


Thanks
