Seagate 100504364 BARRACUDA 7200 11 PCB Circuit Board

1. I had recently an issue with a 7200.11 drive 320 GB in an HP desktop, which was no more seen at BIOS level. After consulting several people locally and going on several forums, I used the workaround proposed for solving the firmware issue identified on the Web (using a serial link and commands). It almost works, but it now seems that there is a issue between PCB and drive. As a consequence I am trying to use a new PCB for recovering the data on the disk.

Before buying it, my question is to know about the compatibility of PCBs, if I buy another (new or used) seagate disk drive for re-using the PCB. For instance, I am asking the following questions:
– is the PCB coming from a ST3320613AS (instead of 813AS) compatible with my drive?
– what are the criteria for assessing compatibility of a PCB with my drive?
*ref of the PCB printed on the board itself (100504364 REV B on my drive) for instance ?
*ref printed on the sticker (100504356 JC91202M2)?
*other?
– is there a need to do something else on the new PCB in order to make it work (I red on some forums about rom swap)?
