Thanks to all who responded to my jumper dilemma. As one of you suggested, trial and error might do the trick and that's what happened. I had to move my Master drive to the bottom slot; put the Hitatchi in the top slot. Change my Master drive to "cable select"--I'm still not sure what it was set on but it had been operating earlier so it wasn't a problem. I'll try to repay the favor one day. Ron in Memphis
