WD5000AAKX-75U6AA0, 2061-771640-103 AC — WD SATA 3.5 PCB

This listing is for the hard drive circuit board (PCB / logic board) ONLY — no hard drive is included. Compatible part numbers: WD5000AAKX-75U6AA0, 2061-771640-103 AC (WD SATA 3.5 PCB). Because we stock a large number of PCBs, the exact board you receive may differ slightly from the photo. These circuit boards are intended for hard drive repairs and data recovery work. Most PCB units contain unique information stored in a ROM memory chip that is required for the drive to function correctly; the ROM chip or its firmware must be transferred to or programmed onto the replacement board. If the ROM can be physically moved, a local computer technician should be able to perform the transplant; alternatively, we provide a complimentary adaptation service for purchases of $60 or more that includes either relocating the ROM chip to the new PCB or reprogramming the board with the correct ROM data. Before ordering, verify compatibility using our Donor Matching Guide and follow the Hard Drive Diagnostics Guide to confirm a PCB swap is appropriate. If a simple PCB replacement does not resolve the issue, we also offer a dedicated PCB Replacement Service — see the Adaptation Service page for full details. If you plan to replace the board yourself, review our PCB Replacement Guide first.
