WD2500AAJS-75M0A0 / 2061-771590-X02 AC — WD SATA 3.5 PCB

This sale is for the hard drive printed circuit board (PCB / logic board) ONLY — no hard drive or additional parts are included. The PCB you receive may differ slightly from the photo due to available stock variations.\n\nThis board is designed for data recovery and hard drive repair tasks. Before purchasing, confirm that a replacement PCB will address your issue by consulting our hard drive diagnostics guide, and verify compatibility using the Donor Matching Guide.\n\nMost WD PCBs contain unique configuration data 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 moved or programmed onto the replacement board. If the ROM chip can be physically transferred, a local computer technician can typically perform the transplant. For DIY repairs, review our PCB Replacement Guide for step-by-step instructions.\n\nFor customers spending $60 or more, we include a complimentary adaptation service: we will either transplant the ROM chip to the new PCB or reprogram the replacement board with the correct ROM data. If a basic PCB swap does not resolve your drive problem, we also provide a dedicated PCB Replacement Service to handle more complex cases — see the Adaptation Service page for full details.
