Subject:   Tape drive not working anymore.........

I had a partition on my FreeBSD machine get messed up, and since I had a
tape backup, I decided to just reinstall everything on the machine
(using 4.1 freebsd instead of 4.0).

Anyways, I reformatted the drive, and installed 4.1. No problems.
I installed BRU 16.0 (since that was the software which did the backing
up to the tape), no problems
I was able to get a bunch of stuff off the tape, rebooted, and ever
since the tape drive is reporting that the tape is empty.
I get the message below when trying to MT the tape.

My system is 4.1 BSD, a Sony SDT9000 (12/24 gig tape drive?) which is on
my scsi card. I was referencing that as rsa0.

Any ideas on what's going on would be great!
