I picked up the exact same model of a Western Digital drive I need to reanimate. The drives differ by 3 manufacturing days.

Unfortunately, when I swap the "good board" into the target drive I get the "click-click" and steady spin of an unrecognized drive.

When I swap the bad board into the "good drive" I don't get any action - just a low-level spin.

This leads me to believe that the logic board of the target drive is indeed fried - although I do not see any damage to the boards.

When I compare the boards side by side, everything looks the same except for one IC chip of the five on each board.

Also, the drives have subtle differences too: the circuit board that connects the drive to the logic board is a different color.

Is there another logic board inside the unit?

Some of the latest WD drives could have extra data on the PCB. For fine tuning the electronics to the hard drive.

Maybe scan the label and PM me?

I've got a WD800JB-OOJCO with a fried board also. Board is 2061 701292 A00 AL. Does the board you have match the one I'm looking for?

There is a 8 pin IC that has a part number starting with 25 that has to be swapped
