I accidentally plugged the wrong power adapter to my 640 gb WD external hard drive. After that, my hard drive won't work anymore. I tried to disassemble my hard drive to see if I could fix the problem.

I thought that I damaged the "serial ata bridgeboard power supply" since I used a wrong power adapter. But then when I disconnected the bridgeboard from the hard drive, I noticed that the light would lit and the light of the bridgeboard would turn off again if i try to connect it again from the hard drive. Can anyone tell me what needs to be done?

There are two parts to this:
The hard drive, and the enclosure (incl the circuit board)

Can you remove the drive and connect it to another PC? Does it work?
The circuitry of the enclosure is likely toast from using the wrong power adapter.
