Hi guys, a newbie here. I have a seagate 7200.10 320gb hard drive and it has been dead since my daughter connected a wrong voltage adapter to the hard drive (it was an external one). I have tried to put it internally into my oc, and also bought a new hard drive case, but the drive remains dead no matter what I've tried. Is there anyway to save some vastly entimental pictures, that cannot be replaced??? Any help greatlfully appreciated

Is it still live, i'e does it show as a slave in the bios load up?

If it does show go look in computer management for it, if it shows up but isn't readable you are in luck, you need to obtain a program called Power Data Recovery, this will find the drive and anything still intact on it and recover it to another HD for you, it's a top notch program, no need to wonder if you will have wasted money on it, as long as Windows can see the drive and it still spins it will work, hth.

A quick check method is to use Seatools in Windows if it finds the drive it should all work.

You could try swapping the logic board. You might be able to get one (or an entire identical working drive) on eBay. If that doesn't get the drive to spin and detect, you might be out of luck, short of hiring a data recovery company.

AFAIK Seagate hard drives have protection diodes on the +5V and +12V supply rails. These devices will sacrificially protect the circuit board from overvoltages or reverse polarity.

If you are 100% sure that your PSU is correctly wired and working properly, then you could desolder these protection diodes and run the drive without them.

Can you upload a photo of the circuit board?
