WD SATA 3.5 PCB - WD20EARS-00MVWB0 / 771698-T04 AA

This listing is for the hard drive circuit board (PCB / logic board) ONLY — the hard drive is not included. We carry a large quantity of PCBs, so the actual board you receive may vary slightly from the photo. Intended for HDD repair and data recovery use. Before purchasing, confirm that replacing the PCB will resolve your issue by consulting our hard drive diagnostics guide and verify part compatibility with the Donor Matching Guide. Note: most replacement PCBs include unique information stored on the ROM "memory" chip; that data is required for proper drive operation and must be migrated to the new board. If the ROM chip can be physically moved, a local computer technician can usually perform the transfer. For purchases of $60 or more, we provide a complimentary adaptation service that either transfers the ROM chip onto the replacement PCB or reprograms the new board with the correct ROM data. If you plan to perform the swap yourself, review our PCB Replacement Guide. Should a simple PCB swap not resolve the problem, we also offer a specialized PCB Replacement Service—see the Adaptation Service page for full details.
