Lately some of my jobs, though not always the same ones will fail with the error code E00083ED then set the media to 'End Marker Unreadable'.  Why this is happening I'm really not sure, but even after putting in a new series of tapes the problem continues.  If anyone has some ideas on what's going on please reply.

Equipment:

• Backup Exec 12.5 SP2 (fully patched)
• Quantum PC502 tape drive
• Running on top of Windows Server 2003 SP2 (fully patched)
