WD10S21X-24R1BT0 / 771980-001 05R WD SATA 2.5 PCB

This listing includes the hard drive circuit board (PCB / logic board) ONLY — no hard drive is included. Because we stock a large number of PCBs, the exact board you receive may vary slightly from the photo. These circuit boards are intended for hard drive repair and data recovery work. Before purchasing, confirm that a replacement PCB will fix your drive by following our hard drive diagnostics guide and verify compatibility using the Donor Matching Guide. Most hard drive PCBs store essential, unique information on a ROM memory chip; that data must be transferred to the replacement board for the drive to function correctly. If the ROM chip can be physically moved, a local computer technician can typically perform the transplant. For clients with purchases of $60 or more, we provide a complimentary adaptation service which covers either moving the ROM chip to 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. If a simple PCB swap does not resolve the issue, we offer a specialized PCB Replacement Service — visit the Adaptation Service page for details.
