WD5002AALX-00J37A0, 2061-771640-Q33 04R WD SATA 3.5 PCB (Logic Board)

This sale is for the hard drive circuit board (PCB / logic board) ONLY — no hard drive is included. Because we stock large quantities, the exact PCB you receive may vary slightly from the photo. Intended for data recovery and hard drive repair tasks. Before ordering, confirm that a PCB replacement will resolve your issue by following our hard drive diagnostics guide. Verify compatibility using the Donor Matching Guide. Most hard drive PCBs contain unique ROM 'memory' chip data that is required for proper operation; the ROM chip or its data must be transferred to the replacement board. If the ROM chip can be moved, a local computer professional can typically perform the transplant. For customers with purchases of $60 or more, we provide a complimentary adaptation service that includes either moving the ROM chip onto the new PCB or reprogramming the replacement board with the correct ROM data. If you plan to perform the swap yourself, consult our PCB Replacement Guide. In situations where a simple board swap does not fix the drive, we offer a special PCB Replacement Service — see the Adaptation Service page for more information.
