Replacing the circuit board is only applicable to faulty hard drives that are not running.

If your hard drive has rotation, abnormal noise, slow rotation, or squeaking sound, it cannot be repaired successfully by replacing the circuit board.

We hope that every customer who purchases circuit boards has a certain level of repair skills, because some circuit boards cannot be directly recognized as hard drives as soon as they are replaced on the disk body. Each hard drive disk body and its original circuit board are one-to-one, which is a BIOS chip. So it is necessary to replace the BIOS chip of the original circuit board (i.e. the faulty board) with the circuit board we sell, so that the hard drive can be recognized.

If you are unsure where the BIOS is located, please contact the store customer service.
