Can anyone out there help me? I fried my logic board and want to try a replacement. Having a VERY hard time finding one with the correct firmware.
Here's what I need it for:
Seagate Barracuda 7200.11
I would also totally be willing to buy the drive if someone has it....
Thanks in advance!
Solved! Go to Solution.

I have the same problem. I overvolt my drive with 19V by mistake.
It is a Seagate ST3500320AS Barracuda 7200.11 500GB SATA
Board Number: PCB 100466725
REV A DLAJ-4
Date Code: 09161
Site Code: WUXISG
Product of China
This HDD was in an external freeagent that by mistake was supplied with 19V voltage. I took out the HDD and checked it as an internal to my computer but unfortunately when this HDD is plugged on, the computer doesn't start at all. I assume that its circuit was burned. I am about to order a new PCB with these characteristics:
Main Controller IC: ST V523C or LSI TT85501C
HDD Motor Combo IC: 100369972
Cache Memory: 16MB
Board Number: 100466725
This is the only PCB I found in the market. I was hopping that it might work if I just replace PCBs but as the firmware is different I have less chances. There are many things that puzzle me:
If I put the PCB above in the place of mine as it is, is there a chance to see my data and if not, is there a possibility to make things worse damaging the HHD and loosing data?
If I swap the PCBs and use seagate's Firmware Update Utility, will this help the PCB to read the data from my HDD?
My final solution is to "transplant the 8-pin serial EEPROM chip from patient to donor" as you said but from the useful article that you hared withus, I can see that this job needs an expert in order transplant these chips. I believe that special equipment is needed as chips are welded on the circuit and are not just socketed on a socket like the on of a motherboard's bios chip. Is that so?
(I hope my point of view was comprehensible. It was difficult for me to use the appropriate terminology.)

Yes I did overvolt the drive. Smelled burning, the whole deal.
Here is a photo of the front of the board - I have to get the right tools to remove and shoot the front.
Any suggestions? Or do you need to see the front too...?

fzabkar you were absolutely right. The photo matches with my damaged board. But, I removed the board and didn't see anything fried as I was expecting.
Next step is to find multimeter to check the diode's health.
You can see my PCB here

Here is the component side of the board:
Of course I could be wrong, but to me it looks a little "fried" in parts. In fact - the area highlighted in the image you posted, is the same area that appears to be effected on my board.

Is this the 12V TVS diode? Would I be able to replace just this - or do I need a whole new board?
Thank you so much for your time - I really appreciate it.
