You have the BUSY error. The other error (0 LBA) allows the BIOS to recognize the drive, but lists it as a 0 Gb HD.

As I say, if I were you, I would prefer to use the phone cable method, since is easier. a generic DKU-5 worked for me perfectly, even in Vista 64. The RS-232 method is effective as well, but I just think the phone cable method is quicker. Your hopes should be high anyway, since both methods are highly effective.

I did it with the board unscrew and is not that complicated. All you have to be is a little careful.

Then, I remove completly the pcb from the HD and connect RX and TX wires to the TX and RX of the converter

Is the data ground connected to pin 2?

Try this.

I thought that it was not necessary when using the rs232-ttl converter, but I'll try.

Thanks!!!

No tienes un cable de Nokia a la mano?. Te digo porque yo lo hice con un DKU-5 y funcionó a la primera

I'm glad to report that I was able to fix my ST3500320AS even in Vista 64. I tried first with a CA-42 that I pressume it was defective (the PC never saw it), but then I found an generic DKU-5 (chinese) that used a driver from Prolific, and they have one compatible with Vista 64.

All data was intact. Thanks a lot!

BTW, for those who expect a loopback from hyperterminal, I have to confess that I didn't have any response until I connected the PCB. Just then I got the "F3 T>" prompt.

Well, I got an used CA-42 cable but it's not recognized by Vista or XP (using VM Ware). If I plug the cable, nothing happens. I have the drivers installed. I chopped off the connector and peeled the wires (by the way, this CA-42 has 5 wires, white, blue, red, yellow and black). The USB connector says "NOKIA Type: CA-42". Maybe this person sold me a defective cable, or a different one?. It didn't cost me almost nothing, fortunately, like 3 bucks.
