Error with sense data

[David Licht]

Apr 17 11:42:25 demo kernel: st0: Error with sense data: Deferred st09:00: sense key Medium Error
Apr 17 11:42:25 demo kernel: Additional sense indicates Track following error
Apr 17 11:42:25 demo kernel: st0: Error on write filemark.

I get these error whenever try to write to a dds-4 dat drive. I tried three different dat drives, different scsi cable, different controllers, and different tape and have cleaned the drive multiple times.

My system is runnning rh 9.0 linux.
The tape status say's it's ready.

Has anyone seen or heard how to fix this issue?
