On modern drives you typically cannot change PCBs

The mechanical portion of the drive is married to a PCB during the manufacturing process, and the eeprom on the PCB has data specific to the physical characteristics of the drive.

In the 'old days' I have swapped PCBs and it worked. I tried this on a newer vintage Seagate 20gig drive and the result was the most horrible grunting/squeaking sounds you ever heard come from a drive. The drive was OK, but the voice-coil driver chip on the PCB had been shorted out.
