WD40EFRX-68WT0N0 / 771945-F02 AA — WD SATA 3.5 PCB (Logic Board Only)

This listing is for the hard drive circuit board (PCB / logic board) ONLY — no hard drive is included. Because we have a large quantity of PCBs in stock, the specific board you receive may look slightly different than the photo. These PCBs are intended for hard drive repair and data recovery tasks. Before purchasing, confirm compatibility using our Donor Matching Guide and run the checks in our Hard Drive Diagnostics Guide to verify a PCB swap will resolve your issue. Most WD PCBs contain unique ROM data that is required for proper operation; the ROM chip or its contents must be transferred or reprogrammed on the replacement board. If moving the chip is possible, a local computer technician can usually perform the swap. For customers spending $60 or more, we provide a complimentary adaptation service that includes either transplanting the ROM chip onto the new PCB or reprogramming the board with the correct ROM data. If a simple board replacement does not fix the problem, we also offer a dedicated PCB Replacement Service — see the Adaptation Service page for full details and options.
