Seagate SATA PCB Computer Accessories sku-137759469

This Seagate Computer Accessories listing, sku-137759469, is for a ST3320620NS SATA 3.5 hard drive circuit board only (9BL14G-303 / 3. AEK / 100419004 D). No hard drive is included. UPC: 638353008277. The board received may differ slightly from the photo. This replacement PCB is intended for hard drive repair and data recovery.

Before buying, use the hard drive diagnostics guide to check whether a PCB swap will help, and use the Donor Matching Guide to verify compatibility. Most hard drive PCBs store configuration data in a ROM chip; the chip or its contents must be transferred to the replacement board for the drive to operate properly. A local computer technician may be able to transplant the chip.

For purchases of $60 or more, a complimentary adaptation service can transplant the ROM chip or program the replacement board with the correct data. Review the PCB Replacement Guide before doing the swap yourself. If a simple swap does not resolve the issue, a specialized PCB Replacement Service is also offered; see the Adaptation Service page for details.
