I'm pretty sure its the "Idle device timeout" that we set on our jukeboxes
to clear the media out of the drive, and we did this to ensure that the
shared NDMP drives are available as soon as possible.  Specifically I
remember it being the one option that was in minutes not seconds.

I'd give the "Idle device timeout" and see if that helps your situation.
