WD3200AAKX-221CA0, 2061-771640-Z03 03P - WD SATA 3.5 PCB (Circuit Board Only)

This sale is for the hard drive circuit board (PCB / logic board) ONLY — no hard drive is included. The part covers WD3200AAKX-221CA0 / 2061-771640-Z03 03P compatible WD SATA 3.5 PCBs. Because we stock a large quantity of boards, the exact PCB you receive may differ slightly from the photo. Intended use: data recovery or hard drive repair. Before purchasing, confirm that a PCB swap will resolve your problem by reviewing our hard drive diagnostics guide and verify compatibility using the Donor Matching Guide. Most drive PCBs store critical calibration and configuration in a ROM "memory" chip; that ROM data is required for proper operation. The ROM chip itself, or its contents, must be transferred to the replacement board. If you cannot perform the transfer, a local computer technician can usually move the chip. For customers spending $60 or more, we include a complimentary adaptation service — either transplanting the ROM chip onto your new PCB or reprogramming the replacement board with the correct ROM data. If you plan to do the work yourself, consult our PCB Replacement Guide. In situations where a simple PCB swap does not fix the drive, we offer a dedicated PCB Replacement Service to handle more complex cases — see the Adaptation Service page for full details.
