WD10EZEX-22BN5A0 / 771829-005 AJ WD SATA 3.5 PCB (Logic Board)

This sale is for the hard drive circuit board (PCB / logic board) only — the actual WD hard drive is not included. Stock levels are high, so the PCB you receive may differ slightly in appearance from the photo. Intended use: repair or data recovery for WD drives using the WD10EZEX-22BN5A0 board (771829-005 AJ) with SATA 3.5 form factor. Compatibility: review our Donor Matching Guide and run the hard drive diagnostics guide before purchasing to confirm this board is suitable for your drive. Important: most hard drive PCBs store unique information in a ROM "memory" chip that is essential for proper operation. That ROM chip or its data must be moved to the replacement board or the new board must be reprogrammed with the correct ROM data. If you can remove and transplant the ROM chip, a local computer technician can typically perform that task. Our offer: purchases of $60 or more qualify for free adaptation service, which includes either moving the ROM chip onto the new PCB or reprogramming the replacement board with the correct ROM data. DIY users should consult our PCB Replacement Guide before attempting the swap. If a simple PCB replacement does not resolve the problem, we also provide a full PCB Replacement Service — see the Adaptation Service page for details.
