Yes, until now.

Overland LoaderExpress LXL1U11 with 11 Slots and 1 LTO-1 drive (HP-Ultrium).

Maybe it's the same.

Maybe.

Hmm, I'm now confused too.

Oh, I'm sorry. You only get problems, if your biggest DLE is bigger than
your tape. Then you must split the DLE in smaller DLEs. That's what I had in
mind.

It's a problem of good software: You set it up and it works and works and
works and you forget how to configure it ;-).

Sorry for confusing.
