Wd Hdd Surge Repair/Recovery Question?
I have a Wd Caviar Green that I accidentally left plugged in to a outlet without a surge protector. It would start up but no detection. I opened it and the Wd power PCB had burns along some of the wires. I removed the outer PCB and the drive board itself had burns where it makes contact with the outer board. I removed that and cleaned a few contacts and reinstalled it.

When I put it in a Sata dock and connect to a mac it spins and recognizes the disk in utilities but the partition sizes are wrong (the disk size is too large but the partitions are all 0), the usb serial is wrong, it says unsupported and the drive never comes in computer.

Is the drive completely dead or could it just be the PCB that has failed? I can order a new board and replace it but do these symptoms sound like a totally dead drive?

Try using WD Lifeguard Diagnostic tool to check your drives health or check S.M.A.R.T status. But I'd suggest if that drive contains critical data that's worth to be recovered then send it to a professional data recovery service. Than doing something that would further lead to permanent data loss.
 
It sounds like the enclosure may have been configured with a 4KB sector size. When you remove the drive from its enclosure and connect it directly to a SATA port, you will be exposing the drive's native 512e LBAs. The partitions will then appear to be smaller by a factor of 8.

The drive is a WD Green 3tb doesn't look like the drive itself is damaged. I do know that a surge can cause the write heads to become fried. It spins in the dock tho.
