The Seagate site only talks about slowing the drive down for older SATA controllers by jumpering the left two pins. I have yet to find any information as to the actual designation of these four pins, other than the pinouts listed in this thread. So I not sure if I've been wasting the last two weeks and $100-plus trying to fix the drive. What bothers me is that I viewed a YOUTUBE video were a guy stated that the OEM Seagate drives have nonfunctonal jumper pins compared to the retail harddrives. (I'M STARTING TO GET REALLY ANNOYED HERE!!!) Even worse the computer does not recongize the USB converter before or after the Nokia Software is installed. Again unfortunately if you open it, the unit is internally sealed with heavy copper and shrink wrap. You have to carefully cut it open, because it is completely molded as one unit.

As you can see from the third picture, the unit is made in Thailand, not China like in the previous posts.

I finally bit the bullet and purchased an actual Nokia CA-42 data connector, but this was even worse. Seems like the converters were at fault although they were recognized as comm ports. I purchased an identical Seagate 1.5 TB drive that is fully functional, but I cannot communicate with it either. Unfortunately, I cannot communicate with the bricked drive. When I jumper my supposed Rx and Tx lines, I do get echo commands on Hyperterminal. The first two connectors (front/back pictures) are recognized as a Prolific USB-to-Serial Comm Port (Com2), but I cannot transfer data. Once again as you can see from the pictures, not all CA-42 connectors are created equal, and none of them have any designations. I still am having no luck connecting the 'semi-connected' harddrive board to my PC, probably because I cannot determine the correct wiring with the many CA-42 connectors I have purchased.
