Seagate ST3750330NS 9CA156-510 (SN16 / 100534274 B) SATA 3.5 PCB

This sale is for the hard drive PCB / logic board ONLY — no drive enclosure or platter assembly is included. Because we stock a large quantity of these boards, the exact PCB you receive may differ slightly from the photo. Intended for drive repair and data recovery tasks, this board is compatible with Seagate ST3750330NS models that use the 9CA156-510 (SN16 / 100534274 B) configuration. Before ordering, confirm that a replacement PCB will resolve your issue by following our hard drive diagnostics guide and verifying compatibility with the Donor Matching Guide. Important: many Seagate PCBs hold unique configuration data in the ROM (memory) chip; that data is required for correct drive operation. The ROM chip or its stored data must be transferred to the replacement board — this can often be handled by a local computer technician if the chip itself can be moved. For customers spending $60.00 or more we include a complimentary adaptation service which covers either transplanting the ROM chip onto the new board or reprogramming the replacement PCB with the correct ROM data. If you plan to perform the swap yourself, consult our PCB Replacement Guide. If a straightforward PCB swap does not fix the problem, we provide a full PCB Replacement Service—see the Adaptation Service page for details.
