Not on any HVD controller I've ever used. Had a customer burn out an 
LTO2 drive a few weeks ago by plugging it into an HVD controller. Didn't 
burn it too badly, but the interface card on the drive is shot. A 
bus-scan will see it, but it hoses any bus its plugged into and refuses 
to allow anything on the bus to negotiate.

Speaking of which, Anyone have a source for IBM LTO2 controller boards?
