Hard disc drive PCBs(print circuit boards) for IBM and Hitachi HDD data recovery and repair needs. If the HDD can't spin, you can't hear any noise or just hear a tick sound, which means the PCB is probably faulty. Most HDD PCBs' failures are caused by Motor Controller Chip burnt, then the TVS diodes burnt and Main Controller IC burnt.
For common user, the best way is swapping PCB boards. Please send your PCB's photo (the side with chips) to us and also please advise the number on the Main Controller IC. IBM/Hitachi PCB boards compatibility: IBM/Hitachi PCB swap guide
