Seagate ST500DM002 (1BD142-021 / HP73 / 5701 AM) SATA 3.5 PCB

This listing is for the hard drive PCB / logic board only — no hard drive is included. Because we have a large inventory, the exact circuit board you receive may differ slightly from the photo.\n\nThe PCB is intended for use in data recovery or hard drive repair. Before purchasing, verify that replacing the PCB will resolve your issue by following our diagnostics guide. Confirm compatibility using the Donor Matching Guide to ensure a proper match.\n\nNote: most Seagate PCBs contain unique data in a ROM ("memory") chip that is required for the drive to function correctly. The ROM chip or its contents must be transferred to the replacement board. If the ROM chip can be moved, a local computer repair professional can usually perform the transfer.\n\nFor customers spending $60 or more, we include a complimentary adaptation service that either moves the ROM chip to the new PCB or reprograms the replacement board with the correct ROM data. If you plan to perform the swap yourself, please review our PCB Replacement Guide first.\n\nIf a simple PCB swap does not fix the problem, we also provide a dedicated PCB Replacement Service to address more complex issues — see the Adaptation Service page for full details.
