A firmware transfer is the process of transferring the firmware, which is the software code that controls the behavior of a device, from one circuit board to another. This is necessary when replacing a damaged PCB with a new one that has a different firmware version, or when repairing a PCB that has a corrupted firmware. In such cases, the firmware transfer ensures that the new or repaired PCB is able to communicate properly with the hard drive components and that the hard drive functions correctly.
