its trying to write the end of file mark and fails... if this is solaris, you
can do netstat -k and look for st<tape driver instance #>, it will show you
error counts on the drive... you can also look in the syslog, it should show
the driver returning the write error along with the other info. your getting
errors across all your drives and with diff tapes... we had something similar
and it turned out to be really bad drives (and drive tech, damn exabyte)

Ive been experiencing quite a few error 84 (media write error) lately.
A job will start running and then I'll notice in the activity monitor that
the "KB per Second" number for some of the streams shows the same number
ie: 17804 at which point I know that those jobs are going to fail and I'll
end up with an error 84 for those streams. The job will then start again,
sometimes using the same media, sometimes a new media, but it will
generally succeed the second time.
Any ideas as to what is causing the first job to fail ?
