Seagate ST500DM002 1BD142-301 KC44 5701 AG SATA 3.5 PCB (Logic Board)

This listing includes only the hard drive PCB (logic board); no hard drive is included. Because we have a large inventory, the exact circuit board you receive may differ slightly from the pictured item. Intended for hard drive repair and data recovery projects. Before purchasing, confirm a PCB swap will resolve your issue by following our Hard Drive Diagnostics Guide and verify compatibility with the Donor Matching Guide. Many PCBs store unique identifiers and configuration in a ROM "memory" chip — this data is required for the drive to operate correctly. The ROM chip or its contents must be transferred to the replacement board. If the ROM chip can be physically moved, a local computer technician can usually perform the transplant. For orders of $60 or more we provide a complimentary adaptation service that covers either moving the ROM chip to the new PCB or programming the replacement board with the correct ROM data. If you prefer to do the work yourself, consult our PCB Replacement Guide. Should a simple board exchange not fix the drive, we also offer a comprehensive PCB Replacement Service — see the Adaptation Service page for full details.
