WD2500AAJS-75M0A0 2061-771590-X06 AB WD SATA 3.5 PCB (Logic Board Only)

This listing is for the hard drive circuit board (PCB / logic board) ONLY — the hard drive itself is not included. Because we stock a large quantity of PCBs, the exact board you receive may differ slightly from the photo. Intended for use in hard drive repair and data recovery, this replacement board requires careful compatibility checks. Review our Donor Matching Guide to confirm this part will work with your drive, and consult our hard drive diagnostics guide to determine whether a PCB swap will resolve your issue. Many PCBs store unique calibration and configuration data in a ROM chip; that information must be present on the replacement board for the drive to function. If possible, the ROM chip (or its contents) should be transferred to the new board — a local computer technician can usually perform that hardware transfer. For customers spending $60 or more, we provide a complimentary adaptation service that either relocates the ROM chip onto the replacement PCB or programs the new board with the correct ROM data. If you plan to perform the swap yourself, read our PCB Replacement Guide first. When a simple board swap is not sufficient, we also offer a dedicated PCB Replacement Service — see the Adaptation Service page for full details.
