This listing is for a hard drive circuit board (PCB / logic board) ONLY — the hard drive itself is not included. Because we stock a large quantity of these PCBs, the exact board you receive may vary slightly from the picture. These PCBs are intended for hard drive repair and data recovery work. Before purchasing, confirm that a PCB replacement will fix your issue by following our hard drive diagnostics guide and checking compatibility with the Donor Matching Guide. Most hard drive circuit boards contain unique ROM ("memory") data that is required for proper operation; the ROM chip or its data must be transferred to the replacement board. If the ROM chip can be moved, a local computer technician can usually perform the transfer. For customers with purchases of $60 or more, we provide complimentary adaptation service, which includes either moving the ROM chip to the new PCB or reprogramming the replacement board with the correct ROM data. If you plan to do the swap yourself, review our PCB Replacement Guide. If a simple PCB swap does not resolve the problem, we also offer a specialized PCB Replacement Service — visit the Adaptation Service page for more information.
