WD1003FBYX-18Y7B0, 2061-771702-B01 AA — WD SATA 3.5 PCB (Logic Board)

This listing includes ONLY the hard drive circuit board (PCB / logic board). No hard drive is included. We carry a large inventory of these PCBs, so the exact board you receive may differ slightly from the photo. Designed for hard drive repair and data recovery use. Before purchasing, confirm that a replacement PCB will resolve your issue by following our hard drive diagnostics guide, and verify compatibility with the Donor Matching Guide. Many hard drive PCBs store critical, unique data in the ROM chip; that ROM 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 usually perform the transplant. For purchases of $60 or more we provide a complimentary adaptation service that either moves the ROM chip onto the new PCB or reprograms the board with the correct ROM data. If you plan to do the work yourself, review our PCB Replacement Guide first. If a direct PCB swap does not restore your drive, we also offer a dedicated PCB Replacement Service to handle more complex cases — see the Adaptation Service page for full details.
