Meanwhile I moved the controller over to a x86 box to get access to the card' BIOS. I found that the drive is not identified at start by the controller if connected to the external port. So I opened up the DATs case and connected it directly to the inside 50 pin connector and voila... it is identified. Is it possible that his is a problem with my external cable? I got both new today. It is a Centronics to 25 pin cable with an adapter for 25pin to HD68. They didn't have a Centronics to HD68 cable so I choose this way. The cable is 2 meters.
