You have to tweak the SCSI disconnect timing to be somewhat out of spec for it to work properly, and the procedure for doing this with the Quantum drive is probably not universal. I don't agree that an integral drive/scsi controller is the best setup. A separate controller can accomodate two drives. A separate controller gives you additional flexibility in choosing RLL encoding, a buffered controller that can handle an interleave factor of 1, etc. Mike Berger Center for Advanced Study University of Illinois berger@clio.las.uiuc.edu {ihnp4 | convex | pur-ee}!uiucuxc!clio!berger
