Seagate ST3500630AS SATA 3.5 PCB — 9BJ146-305, 3.AAE, 100419004 C

This listing is for the hard drive circuit board (PCB / logic board) ONLY — no hard drive is included. Due to large PCB quantities in stock, the actual board shipped may vary slightly from the pictured item. This PCB is intended for use in hard drive repair or data recovery. To confirm a replacement PCB will resolve your issue, follow our hard drive diagnostics guide and verify part compatibility with the Donor Matching Guide. Most hard drive PCBs contain unique, drive-specific information stored in a ROM "memory" chip; that information is required for correct drive operation. The ROM chip, or its data, must be transferred to the replacement board. If you cannot perform the transfer yourself, a local computer professional can usually move the ROM chip. For purchases of $60 or more we offer a complimentary adaptation service that includes either moving the ROM chip to the new PCB or reprogramming the replacement board with the correct ROM data. If replacing the circuit board alone does not fix the drive, we offer a full PCB Replacement Service — see the Adaptation Service page for more information. If you plan to do the work yourself, review our PCB Replacement Guide.
