Changing densities doesn't generate errors, but it also does nothing else. I've still got some very old (semi-defective) DAT's which I'm going to give a shot. And perhaps go back to my old University group, to see if they still have the drive. :-( --WjW -- Internet Access Eindhoven BV., voice: +31-40-2 393 393, data: +31-40-2 606 606 P.O. 928, 5600 AX Eindhoven, The Netherlands Full Internet connectivity for only fl 12.95 a month.
