Backups

I have been using the hostdump.sh backup script for over a year now and have recently run into a problem. I'm now getting the following error at the end of my jobs;
/bin/mt -f: error fsf'ing tape.

This script uses the native 'ufsdump'. So, I try to go back and read the last dump on the tape (ufsrestore) and I get the response;
Media read error: Error 0

I have tried removing the last file system backed up from the job, but I get the same error from even other machines that are put on the tape. I can read all the other volumes on the tape with no problems, just the last one is failing. This is the HP DLT80e drive and I have used a cleaner tape recently. I've cycled the power on both the tape drive and the host machine. I have also tried retensioning the tape before running the backup. This has happened on at least 10 different tapes, so I know it's not the media. There isn't much to maintaining this drive, I have followed all that HP has outlined. Another funny thing is that I have manually run a backup on a single machine and that completed with no errors. This is an odd problem, but if anyone has encountered anything similar, please let me know. Thank you.

amrmtape

AMRMTAPE(8)						      System Manager's Manual						       AMRMTAPE(8)

NAME

       amrmtape - remove a tape from the Amanda database

SYNOPSIS

       amrmtape [ -n ] [ -v ] [ -q ] [ -d ] config label

DESCRIPTION

       Amrmtape  invalidates  the contents of an existing backup tape in the configuration database.  This is meant as a recovery mechanism when a
       good backup is damaged either by faulty hardware or user error, e.g. the tape is eaten by the drive or is overwritten.

       See the amanda(8) man page for more details about Amanda.

OPTIONS

       -n     Generate new tapelist and database files with label removed, but leave them in /tmp and do not update the original copies.

       -v     List backups of hosts and disks that are being discarded.  Enabled by default.

       -q     Opposite of -v.

       -d     Run in debugging mode so all executed commands are shown.

EXAMPLE

       Remove tape labeled DAILY034 from the DailySet1 configuration.

	      # amrmtape DailySet1 DAILY034
