Seagate Momentus 5400.5 won't power on

[dannunes]

I have a Seagate Momentus 5400.5 320GB Hard drive that won't power on at all. No spinning or whirring when there's power attached - it's just silent. It doesn't show up in Disk Management on Windows or Disk Utility in Mac. I've tried different SATA enclosures, and will see the power on light from those, but always the same results.

Suspecting the PCB and since I coincidentally have a 500GB Momentus 5400.6 with a PCB that's visually identical, I tried to swap them to see if that might work. The drive spun up and made a few clicking sounds before Rosewill SATA dock displayed a red and green light and appeared to power down the drive. I'm hoping that means there's hope if I can replace or repair the correct PCB for this drive. I didn't see anything visibly wrong with the PCB, but have attached a couple pics in case someone's able to spot something I missed.

Full specs on the drive are as follows:
Seagate Momnentus 5400.5 320GB
ST9320320AS
PN 9EV134-566
FW:BS04
Date: 09357
Site: WU

I'd appreciate any suggestions.

ALL PCB's from this model (and indeed series) are absolutely unique, even the s/n is programmed into it.

You need to move the rom chip, which on this model is pretty tricky as its a nasty surface mount chip with a heatsink underneath, easily damaged.

Thanks for the reply, pcimage. I see that you run a data recovery service. Can you give me a ballpark estimate as to what it would cost to recover the data off of the drive, and what would be involved?

You have PM.

Happy to work on the case for you, but maybe you'd be better contacting a pro nearer you?

Thanks! I will have to think about it.

Some older drives have the same basic information on two PCB boards of the same model, provided that both drives were made at about the same time, before more unique adaptives were programmed into the next line of drives. If one of the PCBs fails, there is some chance of making a recovery by simply swapping the boards of the two drives. However, hard drives have contained "customized" firmware on at least an occasional basis since they've become a consumer product, so the chances of a straight "board swap" working are low. So in most cases you also need to move the old PCB's BIOS to the replacement one.
