WD5000AAKX-221CA1 / 2061-771640-S13 AD — WD SATA 3.5 PCB (Logic Board Only)

This listing is for the hard drive PCB / logic board only — no drive, driveshaft, or other HDD components are included. The board fits WD5000AAKX-221CA1 (2061-771640-S13 AD) SATA 3.5 models. Because we maintain a large inventory, the exact PCB you receive may vary slightly from the photo. Intended use: data recovery and hard drive repair. Before purchasing, verify that a PCB swap will address your issue by following our hard drive diagnostics guide and confirm part compatibility using the Donor Matching Guide. Important: most hard drive circuit boards contain unique data stored in a ROM "memory" chip that is required for proper operation. That ROM or its contents must be transferred to the replacement board or the new board must be reprogrammed with the correct ROM data. If a chip transplant is possible, a local computer technician can usually perform the transfer. For customers who spend $60 or more we include complimentary adaptation service — either moving the ROM chip onto the new PCB or reprogramming the replacement board with the correct ROM contents. If you plan to perform the swap yourself, review our PCB Replacement Guide first. In cases where a simple board replacement does not resolve the problem, we provide a full PCB Replacement Service to handle more complex adaptation needs; see the Adaptation Service page for details.
