Western Digital Caviar Green WD10EACS-00D6B1

I had previously posted in the "wanted" section, but now that I have a few donor boards I thought I should move this here to get a bit more help. I would also like to send a big "Thank You" to all the gentlemen that did help me:

Long story Short:

This drive was working perfectly. Unfortunately the computer was having some problems (malware issue) and he disconnected this Sata drive. He then reconnected the SATA drive. The only problem, he tried plugging in one of the Floppy Drive 4 pin power cables to the jumper section on the SATA drive. (Insert Face Palm Here) I purchased a replacement PCB. The drive will spin up fine with the donar pcb, but it will not be recognized in windows it asks to be initialized. I assume the MCU needs to be switched or bios needs to be copied from it to the donor board. The drive will not spin up or anything if I use the original board. Here is what I know and have tried on the dead board:

* I have checked all TVS Diodes (D3 & D4) tested ok

* This PCB does not have a bios chip located at U12

* I have checked the resistors (r64 & r67) tested ok

My only questions now are:

Should I test the voltages on the jumper pins in the dead board?

Should I seek professional help ( both mental and physically by the time I'm done with this )

Anyone have any other ideas?

Is there a trustworthy list of people on this board you would rec? I get messages from people telling me they could do it. But I'm not sure.


Above all else I thank anyone for any advice on this matter.

If you can move the MCU, that would work if it is not fried.

A couple of notable pros here in the forum for the US are jono-ats and harddrivespecialist

The jumper pins connect directly to the MCU's I/O pins. Therefore the MCU is most probably damaged. Testing the voltages at the jumper pins would probably confirm this. In short, there would be no point in transferring the MCU.

As for a "trustworthy list of people on this board", see my PM.

Thank you sir. And for the PM as well.

I will do the following:

Do this with power applied. Set your meter to the 20V range, connect the black probe to SATA power ground or to a screw hole, and use the red probe to test each of the jumper pins. The bottom pins appear to be grounded, but I expect that the upper pins should be tied up to the Vio supply. You can test the board on its own, ie there is no need to install it on the drive.
