Seagate ST3500418AS SATA 3.5 PCB - FW CC46 | PN 9SL142-303 | 5701 U

This sale is for the hard drive circuit board (PCB / logic board) ONLY — no hard drive is included. The board is compatible with Seagate ST3500418AS and carries firmware FW CC46, part number 9SL142-303 and revision 5701 U. Due to a large inventory, the exact PCB you receive may differ slightly from the photo. Intended use: data recovery or hard drive repair. Before purchasing, confirm this replacement will resolve your issue by using our hard drive diagnostics guide, and verify compatibility using the Donor Matching Guide. Important: most hard drive PCBs store drive-specific data in a ROM "memory" chip. That ROM data is required for proper drive operation and must be transferred to the replacement board. If the ROM chip can be physically moved, a local computer technician can usually perform the transplant. For customers spending $60 or more, we include a complimentary adaptation service that either transfers the ROM chip to the new PCB or reprograms the replacement board with the correct ROM data. If you plan to handle the swap yourself, review our PCB Replacement Guide first. In cases where a simple PCB swap does not restore the drive, we provide a dedicated PCB Replacement Service to address more complex problems — see the Adaptation Service page for details.
