WD30EZRX-00D8PB0 / 771945-001 07R WD SATA 3.5 PCB — Logic Board Only

This listing is for the hard drive circuit board (PCB / logic board) ONLY — no hard drive is included. Because we stock a large quantity of PCBs, the specific board you receive may differ slightly from the photo. Intended use: replacement boards are provided for hard drive repair and data recovery purposes. Before ordering, verify whether a replacement PCB will resolve your issue by following our hard drive diagnostics guide. Confirm compatibility using the Donor Matching Guide. Important: many hard drive PCBs contain unique information stored in a ROM memory chip that is required for the drive to operate correctly. That ROM chip or its data must be transferred to the replacement board. If the chip can be physically moved, a local computer technician can often perform the transplant. For customers spending $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 for step-by-step instructions. In situations where a simple PCB swap does not restore the drive, we also offer a specialized PCB Replacement Service to handle more complex cases — see the Adaptation Service page for full details.
