The board on a drive does not cause clicking except in a few WD models. Clicking in a Fujitsu is almost always a head issue which would require pro recovery in a clean room. You must also match more than teh model number for a compatible PCB if it is a PCB issue. Fujitsu PCB failures generally result in the drive not spinning up. If the drive doesn't spin, then the head lock is not disengaged and it couldn't click.
