WD30EZRZ-00Z5HB0 (771945-202 AC) WD SATA 3.5 PCB Logic Board

This listing is for the hard drive circuit board (PCB / logic board) ONLY — the hard drive is not included. Because we stock a large number of PCBs, the exact board you receive may differ slightly from the photo. Purpose: This PCB is intended for hard drive repair or data recovery projects. To confirm a replacement PCB will resolve your issue, please consult our hard drive diagnostics guide and verify compatibility using the Donor Matching Guide. Important: Most hard drive PCBs store unique information in a ROM memory chip that is required for the drive to operate correctly. The ROM chip or its data must be transferred to the replacement board. If the ROM chip can be physically moved to the new PCB, a local computer technician can normally perform that task. Services: For purchases of $60 or more, we provide a complimentary adaptation service that includes either transplanting the ROM chip onto the new PCB or reprogramming the replacement board with the correct ROM data. If you plan to do the swap yourself, review our PCB Replacement Guide first. If a simple PCB swap does not fix the drive, we offer a comprehensive PCB Replacement Service — see the Adaptation Service page for full details.
