Possibly a drive select issue. Some drives had jumpers or switches, some cables have flipped-around wires so the connectors are specific to one drive or another. If your cabling is straight-through with no funny business at the connectors, set the drive to DS0. If the cable has split out and flipped-over sections, DS1 should be set in the jumpers --but then it depends on which connector is used. ...I think, anyway, it's been a few years since I've had to use a 5.25. > I tried that with two TEAC drives to no avail. > > Any clues what I may have forgotten?
