WD SATA 3.5 PCB - WD10EALX-759BA1 (2061-771640-K03 AC)

This listing is for the hard drive printed circuit board (PCB / logic board) only — no hard drive is included. The board is for WD SATA 3.5 drives matching model WD10EALX-759BA1 and part number 2061-771640-K03 AC. Because we stock a large number of PCBs, the exact board you receive may differ slightly from the photo. Purpose and compatibility: These PCBs are intended for use in data recovery and hard drive repair. Before ordering, confirm that a PCB swap is likely to resolve your issue by following our hard drive Diagnostics Guide and verify part compatibility with the Donor Matching Guide. Important ROM information: Most drive circuit boards store unique configuration data in the ROM ("memory") chip. That ROM content is required for the drive to function correctly. You must transfer the ROM chip or its data to the replacement board. If the ROM chip can be physically moved, a local computer technician can usually perform the transfer. For do-it-yourselfers, please review our PCB Replacement Guide first. Adaptation and services: For orders of $60 or more we provide a complimentary adaptation service that includes either moving the ROM chip to the replacement PCB or reprogramming the new board with the correct ROM data. If a simple PCB swap does not resolve the problem, we also offer a full PCB Replacement Service to address more complex issues — see the Adaptation Service page for details.
