WD2500AAKX-193CA0 / 2061-771640-S13 AA — WD SATA 3.5 PCB (Logic Board)

This listing includes the hard drive circuit board (PCB / logic board) ONLY — the hard drive itself is not included. Photo shown is representative; because we stock a large number of PCBs the exact board you receive may differ slightly from the image. Intended for hard drive repair or data recovery use. Before purchasing, confirm that a replacement PCB will address your problem by following our hard drive diagnostics guide, and verify compatibility using the Donor Matching Guide. Most hard drive PCBs store unique calibration and configuration data in the ROM "memory" chip; that ROM data must be present on the replacement board for the drive to function correctly. If possible, the ROM chip can be physically transferred to the new PCB — a local computer technician can usually perform this task. For purchases of $60 or more we provide a complimentary adaptation service that either moves the ROM chip to the replacement PCB or reprograms the new board with the correct ROM data. If you plan to perform the swap yourself, review our PCB Replacement Guide first. Should a simple PCB swap not resolve the issue, we also offer a full PCB Replacement Service—see the Adaptation Service page for details.
