I sure hope not. I did find some posts on the Seagate forums with people having success sending it in. I think I'll give it a try today given my results below. Interesting... I had assumed it loaded the diag commands off the platter because if I do a Z/U cycle with the contacts still disconnected, and it fails to spin up because of that, then attempting to run the N1 command gives me "Unable to load Diag Overlay".

This matches this guy: http://www.dslreports.com/forum/r22209346- http://www.dslreports.com/forum/r22237565- who also has a drive labeled SD15 but with SX15, the BSY problem, and the same "Unknown Diag Cmd Failure 12CC4" error message. Thanks!
