Seagate Barracuda 500M ST3500620AS HELP! HELP! Please I am trying to recover this HD showing BIOHD-2 Error code, BIOS does not recognize it at all. I reworked a Nokia ca-53 USB cable. I used GND (pin 4 on USB), Data+ (pin 3 on USB) as RX on HDD, Data- (pin 2 on USB) as TX on HDD. My main problem in that connecting the USB cable to a working PC I get the message "unknown USB device", so I do not have any possibility to start Hyperterminal, is anybody able to suggest me a solution. Forget me if my english is not so good, I am Italian and I am trying to do my best. Thanks in advance, Silverfox (maybe not to smart as a fox!)
