WD SATA 3.5 PCB — WD20EARS-00MVWB0, 2061-771698-002 04P

This listing is for the hard drive circuit board (PCB / logic board) ONLY — no hard drive is included. We stock a large number of PCBs, so the unit you receive may differ slightly from the photo. Designed for use in data recovery and hard drive repair, this board is intended as a replacement part for compatible WD drives. Before attempting a swap, consult our hard drive diagnostics guide to confirm a PCB replacement will resolve your issue and review the Donor Matching Guide to ensure compatibility. Many WD PCBs store unique calibration and configuration data in the ROM (memory) chip; that information is required for the drive to function properly. The ROM chip or its data must be transferred to the replacement board. If the chip can be physically moved, a local computer technician can typically perform the transplant. For purchases of $60 or more we include a complimentary adaptation service that covers either moving the ROM chip to the new PCB or reprogramming the replacement board with the correct ROM data. If a simple PCB swap does not fix the problem, consider our specialized PCB Replacement Service. See the PCB Replacement Guide or visit the Adaptation Service page for full details.
