Seagate ST3160023AS SATA 3.5 PCB - 9W2814-633 / 8.12 / 100340680 M Hard Drive Logic Board

This listing is for the hard drive circuit board (PCB / Logic board) ONLY — the hard drive itself is not included. Because we stock large quantities, the PCB you receive may differ slightly from the photo. Designed for data recovery and hard drive repair, this Seagate PCB corresponds to models and identifiers: ST3160023AS, 9W2814-633, 8.12, 100340680 M. Before purchasing, confirm that a replacement board will resolve your issue by consulting our Hard drive diagnostics guide and verify compatibility using the Donor Matching Guide. Important: most hard drive circuit boards store unique information in the ROM "memory" chip; that data is required for the drive to function properly. The ROM chip or its data must be transferred to the replacement board. If the chip can be physically moved, a local computer technician can usually perform the transfer. For customer orders of $60 or more we provide a complimentary adaptation service that includes either transplanting the ROM chip onto the new PCB or reprogramming the replacement board with the correct ROM data. If you plan to perform the swap yourself, please review our PCB Replacement Guide first. Should a simple PCB swap not fix the problem, we offer a dedicated PCB Replacement Service to handle more complex cases — see the Adaptation Service page for full details.
