You'll need to poke around the VMS web sites for the drivers Looks like it does MSCP - I don't know why you'd need special drivers unless maybe to support non-standard sized drives. That shouldn't matter either. MSCP gets the device size from the device; one of the big points of MSCP is to do logical block addressing and leave geometry as a device detail. I'd be surprised if VMS got this wrong... paul
