WD20EARS-22MVWB0, 2061-771698-802 AA, REV P1 — WD SATA 3.5 PCB

This listing is for the hard drive circuit board (PCB / logic board) ONLY — no hard drive is included. Because we stock large quantities, the specific PCB you receive may differ slightly from the photo. Intended use: data recovery and hard drive repair. To confirm a replacement PCB will resolve your issue, follow our hard drive diagnostics guide and verify compatibility using the Donor Matching Guide. Most hard drive PCBs contain unique information stored in a ROM ("memory") chip; that data is required for the drive to operate correctly. The ROM chip itself, or its contents, must be transferred to the replacement board. If the ROM chip can be moved, a local computer technician can typically perform the transfer. For customers with orders of $60 or more, we provide a complimentary adaptation service that includes either transplanting the ROM chip onto the new PCB or reprogramming the new board with the correct ROM data. If you plan to do the work yourself, please review our PCB Replacement Guide first. If a simple PCB swap does not fix the drive, we also offer a specialized PCB Replacement Service — see the Adaptation Service page for details.
