WD5000AAKX-003CA0 / 2061-771640-S03 AC WD SATA 3.5 PCB (Logic Board Only)

This listing is for the hard drive PCB / logic board only — the hard drive itself is NOT included. The board corresponds to 2061-771640-S03 AC for WD5000AAKX-003CA0 (WD SATA 3.5). Because we maintain a large inventory, the exact PCB you receive may differ slightly from the photo. These circuit boards are intended for use in data recovery and hard drive repair. To confirm a replacement PCB will resolve your issue, please consult our Hard Drive Diagnostics Guide and verify compatibility using the Donor Matching Guide. Important: most hard drive PCBs contain a unique ROM (memory) chip that holds data required for proper operation; the ROM chip or its stored data must be transferred to the replacement board or the new board must be reprogrammed with the correct ROM data. If relocation of the chip is possible, a local computer technician can typically perform the transplant. For purchases of $60 or more we include complimentary adaptation service, which covers either moving the ROM chip to the new PCB or programming the replacement board with the correct ROM information. If you plan to perform the swap yourself, review our PCB Replacement Guide. In cases where a simple board swap does not fix the drive, we also offer a specialized PCB Replacement Service — see the Adaptation Service page for details.
