A bad tape drive can cause this issue by being unable to write the end marker to the tape. Erasing the tape can get this resolved.ģ. A bad tape could cause this issue by corrupting the end marker.

Once this occurs, the tape must be erased and an overwrite job has to be run prior to being able to append to the tape again.Ģ. This happens because it does not know at what point on the tape the last backup stopped writing to it. Backup Exec will then view the tape as "Not appendable" and "End marker unreadable". If the Backup Exec Job Engine service (bengine.exe) stops for any reason during a backup, the end marker on a tape may not be written to the media. Tape Media is marked as "Not appendable(End marker unreadable)" if the Backup Exec Job Engine stops during a backup.ġ.
