Use the following criteria to find a donor drive.

  • Model number: Match the model number exactly.
  • Part number: Match the part number exactly.
  • Heads map: Match the physical heads (PH) map exactly. It is OK if the donor has more heads than the original drive, but all heads before that should match.
  • MLC: Match the MLC exactly.
  • Date of manufacture: Should be within three months — the closer the better.
