Seagate ST3500630AS SATA 3.5 PCB — 9BJ146-621 | 3.AHG | 100406528 C

Product is the hard drive circuit board (PCB / logic board) ONLY — no hard drive included. Because we maintain a large inventory, the actual PCB shipped may vary slightly from the photo. This PCB is intended for hard drive repair and data recovery applications. Before purchasing, confirm that a replacement board will resolve your issue by using our Hard Drive Diagnostics Guide, and verify compatibility with the Donor Matching Guide. Most Seagate PCBs contain unique information stored in a ROM memory chip that is required for proper drive operation; that ROM or its data must be transferred or reprogrammed onto the replacement board. If the ROM chip can be relocated, a local computer repair professional can usually perform the transfer. For orders of $60 or more we provide 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 you plan to perform the swap yourself, review our PCB Replacement Guide. In situations where a simple board swap does not resolve the problem, we offer a dedicated PCB Replacement Service — see the Adaptation Service page for full details.
