  2. There is obvious damage on the PCB board
  3. The hard drive does not spin (the hard drive never fell or was shaken)
  4. If the hard drive simply can't be detected, or if it is clicking, then it could be a circuit board problem, but it could easily be internal damage as well. It is often a gamble in this case.

Please note that this item can fix drives with ONLY circuit board problems. Some drives have internal damages that can't be detected easily. Please do NOT attempt to open the drive without a clean room. There is no return policy for this item.
