Seagate ST3750330NS PCB (9CA156-783 / HPG8 / 100468979 J) — SATA 3.5 Logic Board

This listing is for the hard drive circuit board / logic board (PCB) only — the hard drive itself is NOT included. The board matches Seagate ST3750330NS (part IDs 9CA156-783, HPG8, 100468979 J) for 3.5" SATA drives. Because we stock a large number of PCBs, the exact board you receive may differ slightly from the photo. Intended use: data recovery and HDD repair. Before ordering, confirm that a replacement PCB will resolve your issue by consulting our hard drive diagnostics guide, and verify compatibility using the Donor Matching Guide. Important: most hard drive PCBs contain unique data stored in a ROM (memory) chip. That ROM data is required for the drive to function correctly and 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 customers placing orders of $60 or more, we provide a complimentary adaptation service that includes either transplanting the ROM chip onto 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 first. In cases where a straightforward PCB swap does not restore the drive, we also offer a dedicated PCB Replacement Service to handle more complex adaptations — see the Adaptation Service page for full details.
