WD fried board and which is a ROM chip

[alibegoa]

I fried my two WD 1T HDD PCBs. Unfortunately living in a location where there is no data recovery service, so after reading mr google, I found out that I need replacement PCBs but that I will also need to change over a ROM chip from burnt out PCB to the new one.
I found two exactly same PCBs online, I received them, but there is no way I can find out which is exactly a chip that I need to replace.
If someone can please help and identify what exactly needs to be moved over from old PCB to new one.

Thanks for your assistance.

Hi,

As you can see by the pictures, the PCB's are not equal, CPU is different and none of them has external ROM, so you cannot swap it.

Unfortunately you can't do this on your own.
These boards have no external ROM (U12 is vacant), therefore you will need a pro to do this for you. There is no way you can do this on your own. Sorry.

Judging by the damage on your second pic, I think a damage in preamp is also very likely

Bad news.

He fried two different drives, as I understand it.

Agree, neither of these boards have a rom chip at U12, so DIY is not an option.
