Seagate ST31000528AS PCB sku-428843328 641020057980

This Seagate ST31000528AS listing is for a SATA 3.5 hard drive PCB only; no hard drive is included. The board identifiers are 9SL154-034, CC45 and 4772 M. It is listed under Computer Components as SKU sku-428843328, UPC 641020057980. The circuit board received may differ slightly from the photo. Intended for hard drive repair or data recovery, it requires a compatibility check using the Donor Matching Guide and a diagnosis using the Hard Drive Diagnostics Guide before purchase. Most PCBs hold drive-specific parameters in a ROM chip; the chip or its data must be transferred to the replacement board for correct operation. A local technician may transplant the chip, or the ROM data can be programmed onto the replacement board. Orders of $60 or more include an adaptation service covering either procedure. Review the PCB Replacement Guide before doing the work yourself. If a board swap does not restore the drive, a full PCB Replacement Service is also offered; see the Adaptation Service page.
