TSM 5.5.2 on Windows
3494 classic (aka "old") tape library with TCP/IP connection for the robot, 
four fibre-connected 3592-E05 drives.

A couple of times a week, a tape gets left in drive 4; always that drive, 
different cartridges.
I say "left" instead of "stuck", as there are no dismount errors in TSM, no FID 
codes on the drive.
The CE has replaced the drive twice, so it isn't the drive mechanism.
Firmware on library and drives is up to date.
Can't be the software drivers, as it only affects the 1 drive.

Sequence of events is below;
No dismount error, but subsequent mounts fail because there is a tape in the 

Am I correct that since the ANR8468I indicates a successful dismount, TSM must 
have gotten a "dismount completed" message back from the library over TCP/IP? 
If so that leaves the problem in the robotics, and eliminates any issues with 
the HBA or fibre cables...

What say you classic 3494 owners out there?
