WD40EZRX-00SPEB0, 771945-F02 AB — WD SATA 3.5 PCB

This listing is for the hard drive circuit board (PCB / logic board) ONLY — no hard drive is included. Because we maintain a large inventory of PCBs, the actual board you receive may differ slightly from the photo. The PCB is intended for hard drive repair and data recovery tasks. Before purchasing, confirm that a replacement PCB will address your problem by following our hard drive diagnostics guide, and verify compatibility using the Donor Matching Guide. Most hard drive PCBs store unique configuration data in a ROM "memory" chip; that ROM data is required for correct drive operation and must be transferred to the replacement board. If the ROM chip can be moved, a local computer technician can usually perform the transfer. For customers who prefer assistance, we offer a complimentary adaptation service on purchases of $60 or more — this includes either transplanting 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, review our PCB Replacement Guide. Should a simple PCB swap not resolve the issue, we also provide a specialized PCB Replacement Service — visit the Adaptation Service page for more information.
