HDT722525DLA380 PCB Swap confusion donor selection criteria

[avecvous9]

Hello everybody,
Model: HDT722525DLA380
PCB Sticker: 0A29479 BA1588_

This HDD stopped spinning due to a tiny short-circuit. I tried with another PCB from the same model with closer PCB sticker number (0A29476 BA1588), => the HDD started spinning.
First I tried to check the pcb malfunction but there was no apparent sign for electronic failure (except maybe that there was 0v at the motor's input).
Now I am searching for a PCB to buy but I am somhow confused:
According to Acelab manuel: in order to perform a pcb swap for Hitachi you need to match the:
model and the first two lines of the pcb sticker. In addition to that they talk about a masked rom version in the processor. (of course with NVRAM resoldering)
In the other hand, Effective Electronics, LLC says that 4 things are required to match exactly to do a PCB swap for Hitachi:
-model number
-Part number (P/N)
-MLC
-the first 2 lines of the pcb sticker

I googled for a donor, P/N are impossible to match.
So what do you suggest?
Best regards.

-the first 2 lines of the pcb sticker is enough + Nvram swap

+1 Always works for me. Don't get too confused by the Ace manuals. There's a ton of technical information in there and a lot isn't always necessary for commercial data recovery, just good to know for those rare circumstances and for troubleshooting purposes.
