Seagate PCB-ST9500423AS Hard Drive PCB sku-188742490

Seagate PCB-ST9500423AS is a hard drive logic board listed under Computer Components, SKU sku-188742490 and UPC 643665744935. This sale is for the PCB only; the drive is not included, and the board's revision may differ slightly from the photo. It is compatible with the Seagate ST9500423AS SATA 2.5 drive and is labeled 9RT143-034, 0006DEM1 and 9573 B. It is intended for hard drive repair and data recovery. Before ordering, check the hard drive diagnostics guide to see whether a PCB swap will address the problem, and use the Donor Matching Guide to confirm compatibility. Most hard drive PCBs store drive-specific calibration and firmware data in a ROM chip. The chip or its data must be transferred to the replacement board for the drive to work properly; a local computer technician can usually transfer a removable chip. Orders of $60 or more include a complimentary adaptation service to transfer the chip or program the replacement board with its ROM data. Review the PCB Replacement Guide before doing the swap yourself. If a board swap does not resolve the issue, a full PCB Replacement Service is also offered; see the Adaptation Service page.
