Seagate ST380815AS SATA 3.5 PCB - 9CY131-021 / 3.CHH / 100441714 J

This sale is for the hard drive circuit board (PCB / logic board) ONLY — no drive is included. Because we carry a large inventory of PCBs, the exact board you receive may differ slightly from the photo. Intended use: data recovery and hard drive repair. Before purchasing, verify that a replacement PCB will resolve your issue by consulting our hard drive diagnostics guide and confirm compatibility with the Donor Matching Guide. Most PCBs store drive-specific data on a ROM 'memory' chip; that data is required for correct operation, so the ROM or its contents must be transferred to the new board. If physical chip transfer is possible, a local computer technician can typically perform the procedure. For orders of $60 or more we provide a complimentary adaptation service that includes either transplanting the ROM chip to the replacement PCB or reprogramming the board with the correct ROM data. If you plan to do the swap yourself, review our PCB Replacement Guide. When a simple board swap does not fix the problem, we offer a dedicated PCB Replacement Service — see the Adaptation Service page for full details.
