WD2500AAKX-603CA0 / 2061-771640-S13 AA — WD SATA 3.5 PCB (Logic Board)

This sale is for the hard drive PCB (printed circuit board / logic board) ONLY — the hard drive itself is not included. Model references: WD2500AAKX-603CA0, 2061-771640-S13 AA, WD SATA 3.5. Because we stock a large quantity of these PCBs, the exact board you receive may differ slightly from the photo. Intended use: data recovery and hard drive repair. Before ordering, verify that a replacement PCB will resolve your issue by following our hard drive diagnostics guide, and confirm compatibility using the Donor Matching Guide. Important: most hard drive circuit boards store unique data in a ROM "memory" chip; that ROM data is required for the drive to function correctly. The ROM chip itself, or its contents, must be transferred to the replacement PCB. If the ROM chip can be moved, a local computer technician can typically perform the transplant. For customers spending $60 or more, we include free adaptation service — either transplanting the ROM chip onto the replacement board or reprogramming the new PCB with the correct ROM data. If you plan to perform the swap yourself, please review our PCB Replacement Guide first. If a simple PCB swap does not fix the drive, we also provide a comprehensive PCB Replacement Service — visit the Adaptation Service page for full details.
