Note:Some older drives have the same basic information on two PCB boards of the same model, provided that both drives were made at about the same time, before more unique adaptives were programmed into the next line of drives. If one of the PCBs fails, there is some chance of making a recovery by simply swapping the boards of the two drives. However, hard drives have contained "customized" firmware on at least an occasional basis since they've become a consumer product, so the chances of a straight "board swap" working are low. So in most cases you also need to move the old PCB's BIOS to the replacement one.http://www.hddzone.com/fix_hard_drive_pcb_board.html
