Hello, Im trying to fix my HDD with BSY bug. 500 GB ; ST3500320AS ; Firmware: SD15 I bought CA-42 cable like this one http://reseller.polphone.com/u/product.php?id=69265 Is this cable good to use for my case? I cut the end of the cable and it have 5 wires. Black, White, Blue, Red, Green. I used Voltage multimeter between Black and White and it gives me 3.3 V, then between Black and Blue gives me same 3.3 V, so I assume Black wire is ground and White is RX, Blue - TX. Am I right ? My other question is should I connect 3.3V battery somewhere (for example Red and Green wires or I should just not use those 2 wires) ? Anyway I tried to connect the USB black wire to HDD ground, white to HDD TX and blue to HDD RX, used external PSU for the HDD sata. http://oi42.tinypic.com/s5bl85.jpg Installed the OTI serial port driver the device was sucessful installed. I followed the guide, waited for the HDD motor stop spins and plug the USB and run the hypertherminal (winXP) set the settings but when I press Ctrl+Z nothing happen, so what's wrong ? Update: Ah well I just manage to open the USB and check the electronic board so I saw that white wire is TX and Blue wire is RX, maybe that why I didn't get communication, I will try it later after I swap the wires. Anyway you can answer to some of the other questions above that might help, thanks. Update2: I fixed the BSY bug and my HDD works well now and I saved all my data, I'm so happy. I just used the CA-42 cable and only the 3 wires (black - GRND, white TX, blue RX) connected them to the HDD, i didn't add any battery and I didn't used the red or green wire at all. Then I just followed the guide, I did the extra step with F712 + F,,22 commands and it was successful then before the last step I didn't turned off the HDD , just did the / command then m0,2,2,0,0,0,0,22 command and it was successful then my HDD was fixed..
