We first look at the following two pictures. Picture 1 is the “BIOS CHIP” of the circuit board. When we replace the PCB, we need to replace the “BIOS CHIP” with your original PCB.
Picture 2 shows the “Board Number” of the board, and the “Board Number” must be the same!

Note: When repairing a hard disk with a damaged circuit board, we must first ensure that the damage of the hard disk is caused by a circuit board failure. Usually it is relatively simple to replace the circuit board. The tools we need are heat guns, tweezers, etc., you can also find a local repair shop to help you complete this work.
