Data recovery required.

February 10th, 2011, 3:16

Hi,

I've fried three hard drives by negligently putting a molex to sata power adapter in on reverse thus sending voltages down the wrong way. I've attempted DIY and gone through troubleshooting steps, but I dont have the technical means to fix.

Being a student I lack the funds for a 'professional' recovery, but I'm hoping someone might be able to do the job for a lesser fee. You can find background on the drives and my attempts to repair here:
three-fried-hard-drives-did-bad-t18381.html (and also here: http://forums.whirlpool.net.au/forum-re ... ?t=1615579 )

In short:
1 WD 750GB Caviar Green with fried smooth chip; firmware embedded in MCU thus was not able to transfer to new PCB without technical knowledge and appropriate tools.
1 1TB ST31000333AS I transferred the ROM chip to new (identical) PCB, and whilst the drive powers up and detected by bios, am not able to access and I'm led to conclude either ROM chip was damaged, or drive itself is damaged.

It's the caviar green that I want to save most.

Please PM me if you can help, or know who to ask. Willing to supplement crippled fee with shoe polishing, car washing, paper fetching, and being stupendously nice...

Cheers!
Richard.

Richard,

ask fzabkar to help you, he is in Australia.
He should be able to help you for minimal cost or maybe even free.
Maybe you can ship those drives to him for a repair.

My advice is free, but my labour is not. That said, the OP has exhausted his DIY possibilities. Therefore I don't see that there's anything more that I could do. However, I would be interested in tracing the power supply areas of the OP's boards and publishing my findings ... for free.

99% that preamp is fried too
So it is not only PCB now

If it spins up then ROM is fine
According to the "chk...chk...chk... sound and no detection" the preamp is fried

So you have two not very easy internals
I guess it is time to start new life with new data
