Hello,
Your drive can be dirty, are you using smartctl to retrieve drive errors ?
Cleaning tape it can help you, but i don't think that you will be able to
re-read your
tape.
You can tell to bacula to skip this media by editing the bsr file, but i
think that you won't be able
to restore files that are beyong the error. Maybe you can test by using "mt
-f /dev/nst0 fsf 15" and
see if it's work. (error was on file 14)
Bye
