Western Digital hard drive PCB | sku-321262440 638353061876

This Western Digital hard drive PCB is a replacement logic board in Computer Accessories. The hard drive itself is not included. The board is marked 771831-701 AF for a WD2500HHTZ-04N21V0 SATA 2.5 drive. Multiple identical PCBs are in stock, so the board received may differ slightly from the photo. Before buying it for repair or data recovery, use the Hard Drive Diagnostics Guide to check whether a PCB replacement will resolve the issue and the Donor Matching Guide to confirm compatibility. Most hard drive PCBs store unique ROM data that the drive needs to function. The ROM chip or its data must be transferred to the replacement board; a local computer technician can typically move a chip that can be physically transferred. Purchases of $60 or more include a complimentary adaptation service to transplant the chip or reprogram the replacement PCB with the correct data. If doing the swap yourself, consult the PCB Replacement Guide first. A PCB Replacement Service is available for more complex cases if replacing the board alone does not fix the drive; see the Adaptation Service page for details. SKU: sku-321262440.
