Seagate SATA PCB Computer Accessories sku-525999824

This Seagate Computer Accessories listing is for the circuit board (PCB or logic board) only; no hard drive is included. It is identified for the ST3750640NS SATA 3.5 drive as 9BL148-784 HPG1 / 100409233 D. UPC: 641020096262. SKU: sku-525999824. The exact board received may differ slightly from the photo because many PCBs are stocked. The board is intended for data recovery or HDD repair. Check the hard drive diagnostics guide to determine whether replacing the PCB will resolve the problem, and use the Donor Matching Guide to verify compatibility. Most hard drive PCBs store unique configuration data in a ROM chip that the drive needs to operate correctly. Transfer the ROM chip or move or reprogram its data onto the replacement board. A local computer technician can typically transfer a chip that can be moved physically. For purchases of $60 or more, a complimentary adaptation service will either transplant the ROM chip to the new PCB or reprogram the board with the correct ROM data. If you intend to do the swap yourself, review the PCB Replacement Guide first. If a straightforward board replacement does not restore the drive, a specialized PCB Replacement Service is also available; see the Adaptation Service page for details.
