WD2500AAKX-75U6AA0 / 2061-771640-103 AA — WD SATA 3.5 PCB (Logic Board Only)

This listing is for the hard drive printed circuit board (PCB / logic board) only — the hard drive itself is not included. Because we stock a large quantity of these boards, the exact PCB you receive may differ slightly from the photo. Intended use: data recovery and hard drive repair. Compatibility and diagnostics: confirm that this PCB is the correct replacement by following our Hard Drive Diagnostics Guide and the Donor Matching Guide before ordering. Most WD PCBs contain unique configuration data stored in a ROM (memory) chip; that ROM data is required for the drive to operate correctly. The ROM chip or its data must be transferred to the replacement board. ROM transfer options: if the ROM chip can be physically moved, a local computer technician can usually perform the transfer. For customers spending $60 or more, we include a complimentary adaptation service that either transplants the ROM chip onto the new PCB or reprograms the new board with the correct ROM data. DIY and advanced service: if you plan to perform the swap yourself, review our PCB Replacement Guide first. If a straightforward board swap does not resolve the issue, we offer a dedicated PCB Replacement Service to handle more complex repairs — see the Adaptation Service page for details.
