WD20NMVW-11AV3S0, 771961-F00 01P — WD USB 2.5 PCB (Logic Board)

This listing is for the hard drive PCB / logic board ONLY; no hard drive is included. Because we stock a large number of PCBs, the exact board you receive may differ slightly from the photo. These circuit boards are intended for hard drive repair and data recovery tasks. Before ordering, confirm that a replacement PCB will resolve your issue by following our hard drive diagnostics guide, and verify compatibility using the Donor Matching Guide. Most hard drive PCBs store unique information in the ROM "memory" chip; that data is required for correct drive operation. The ROM chip or its contents must be transferred to the replacement board — if the chip can be physically moved, a local computer technician can usually perform the swap. For purchases of $60 or more we provide a complimentary adaptation service that includes either relocating the ROM chip onto the new PCB or reprogramming the replacement board with the proper ROM data. If you plan to perform the work yourself, review our PCB Replacement Guide. If a simple PCB swap does not fix the problem, we also offer a comprehensive PCB Replacement Service — see the Adaptation Service page for details.
