This listing is for the hard drive circuit board (PCB / logic board) ONLY — no hard drive is included. Because we stock large quantities, the actual PCB you receive may differ slightly from the photo. These replacement boards are intended for hard drive repair or data recovery tasks. Before purchasing, confirm that a PCB swap will resolve your issue by using our hard drive diagnostics guide and verify compatibility with the Donor Matching Guide. Most PCBs contain a ROM (memory) chip that holds unique, drive-specific information required for proper operation; that ROM or its data must be transferred to the replacement board. If you cannot move the chip yourself, a local computer technician can usually perform the transplant. For orders of $60 or more we provide a complimentary adaptation service that includes either transplanting the ROM chip to the new board or reprogramming the replacement PCB with the correct ROM data. If you plan to do the work yourself, consult our PCB Replacement Guide. In situations where a simple board swap is insufficient, we also offer a comprehensive PCB Replacement Service — see the Adaptation Service page for full details.
