WD4000KD-00NAB0 / 2061-701310-D00 ACD3, REV A — WD SATA 3.5 PCB (Logic Board)

This listing is for the hard drive circuit board (PCB / logic board) ONLY — no hard drive is included. Compatible part numbers: WD4000KD-00NAB0, 2061-701310-D00 ACD3, REV A; intended for 3.5" WD SATA drives. Because we stock a large quantity of PCBs, the actual board you receive may differ slightly from the photo. This PCB is intended for hard drive repair and data-recovery use. To confirm a replacement PCB will resolve your problem, follow our hard drive diagnostics guide and verify compatibility using the Donor Matching Guide. Most drive circuit boards store unique drive-specific data in the ROM memory chip; that information is required for the drive to operate correctly. The ROM chip or its data must be moved to or programmed onto the replacement PCB. If you can physically transplant the chip, a local computer repair professional can usually perform the work. For customers with orders of $60 or more we provide a complimentary adaptation service that covers either moving the ROM chip to the new board or reprogramming the replacement PCB with the correct ROM data. If you plan to perform the swap yourself, consult our PCB Replacement Guide for instructions. In situations where simple board replacement does not restore functionality, we also offer a specialized PCB Replacement Service — see the Adaptation Service page for full details.
