Just recovered a ST3500320AS SD15 using a Nokia DKU-5 cable (6 wire, similar to CA-42) Pin2(Grnd), Pin4(3.3v+), Pin6(Rx), Pin7(Tx) Used a 3.3 volt motherboard battery for power and grounded all to the molex of the fix PC. Did the procedure and like magic, I got my stuff back safe and sound. Once recovered, flashed to SD1A and all is still well. SMART reports healthy and the drive is now a backup drive. Very pleased with everyone's efforts to document the problem and fix. v/r -Tony
