Seagate Computer Components IDE PCB | sku-120149741

This Seagate Computer Components listing, sku-120149741 (UPC 641020057560), includes only the hard-drive circuit board or logic board, not the drive. It is intended for data recovery or repair of drives matching ST3500830A, 9BJ036-500, 3.AAC and 100406542 F. The IDE 3.5 PCB you receive may look slightly different from the photo because multiple boards are in stock. Before buying, use the hard-drive diagnostics guide to check whether a replacement board will fix the problem, and check compatibility with the Donor Matching Guide. Many boards store unique calibration and configuration data in a ROM memory chip. The chip or its contents must be transferred to the replacement board for the drive to operate correctly; a local computer technician can usually move the chip if you cannot. Orders of $60 or more include a complimentary adaptation service that transfers the ROM chip or programs the replacement board with the correct data. Review the PCB Replacement Guide before doing a swap yourself. If a board swap does not fix the issue, a dedicated PCB Replacement Service is also offered; the Adaptation Service page has details.
