I have a WD MyBook external HDD. My WIFE somehow managed to plug in a laptop power supply (19v) into it.

The external controller seems fine, but the HDD itself does not work.

The circuit board (HDD controller?) on the bottom of the HDD smokes when I plug it in. I was able to take off that circuit board but I don't have another HDD that matches it.

Is there any way to fix this, wether by replacing just the circuit board or buying the exact same model HDD and swapping the circuit boards to salvage the pics and such STORED on it or is the HDD just a lost cause?

Is there even anywhere I can find just the cirtuit board? I'm rather competent with disassembling/reassembling PARTS so that's not an issue.

ThanksYou fried the circuit board on the bottom of the drive itself?

You're looking at a lost cause when it comes to fixing that drive. Invest in another...it'll save you time and aggravation. It's cheaper to replace it.I just want to salvage the data stored on it and wondered if replacing that circuit board would allow me to do that. /shrug I already have a replacement, but the HDD is a different model (SATA instead of IDE) so no luck with that.You would have to find a WD HDD of not only the same model# but with serial #'s as close as possible to yours as they are built in batches for this to work...
I've managed to do it 2 or 3 times over the years but the circuit boards need to be as close to identical as possible for it to work.
Try E-Bay.

The only other option would be a data retrieval service which few of us can afford.
