Replacement WD5000AAKS-00TMA0 Controller 2016-701477-800 AC

October 10th, 2011, 2:43

Power supply in my PC died and seems to have taken the controller on my WD5000AAKS-00TMA) out with it.

The hard driver spins up and is recognized by the BIOS (e.g. shows that the drive is on channel 1) and properly IDs it as a WD5000AAKS but nothing past that...

Interesting thing is that when I have that drive plugged into the SATA port, none of the other SATA drives work -- but remove it from the SATA port and the other drives work fine. That's why I'm concluding that it's a friend controller. No clicking or other nasty noises from the drive.

Doing a quick visual inspection of the existing controller, there appears to be dark discoloration on one end of each of the following: c27, c37, the unlabelled cap right next to c37, c4, and c6. I can't tell if that discoloation is an issue (e.g. a burn) or if I'm just lookoing too closely with paranoia.

If anyone had a lead on a replacement WD5000AAKS-00TMA0 Controller (2016-701477-800 AC) please contact me.

Thanks - your help is GREATLY appreciated.

May be possible a PCB but more likely some firmware issues, or something else.

Either way you need pro assistance as the PCB's on these drives aren't interchangeable.

There is a small possibility that the PCB is suspect, but this one does not have external ROM at U12 so you cannot easily transfer the required info from the suspect board to a donor, specialist (expensive) equipment is required for this.

Your model is a member of the Tornado family. This family is afflicted with an MCU fault (Marvel 88i6745-TFJ1) that mimics a head or media fault.

At least one board supplier in this forum offers free firmware transfers.
