We know PCB includes 2 parts: Hardware (components) and Firmware (data in the chip); The firmware includes HDD's unique configuration data. The HDD needs this unique configuration data to work. In order to have same circuit board firmware, we have to transfer the unique configuration data from the bad board to the good donor board.
