If in doubt and it doesn't cost you anything, have STK replace the suspect
drive. I can say that because we don't use Seagate drives so I know I'll
never get that one :^)
I don't suspect the robot firmware, as it appears the tapes are being
loaded and unloaded properly, but since STK is going to be on-site anyway
you might want to have them upgrade all your drives to the latest firmware.
