Seagate ST3500630NS 9BL146-302 3.AEG 100419004 A1 SATA 3.5 PCB (Logic Board Only)

This listing is for the hard drive circuit board / logic board only — no hard drive is included. Part corresponds to Seagate model ST3500630NS (9BL146-302, 3.AEG, 100419004 A1) and is intended for SATA 3.5 drive repair or data recovery. Because we maintain a large inventory, the actual PCB you receive may differ slightly from the photo. Before purchasing, confirm that a replacement board will resolve your issue by following our hard drive diagnostics guide and verify compatibility using the Donor Matching Guide. Most Seagate circuit boards contain unique configuration data stored in a ROM "memory" chip; that ROM data is required for the drive to function correctly. The ROM chip or its contents must be transferred to the replacement board — if the chip can be moved, a local computer technician can perform the transfer. For customers spending $60 or more, we include a complimentary adaptation service that either relocates the ROM chip onto the new PCB or reprograms the replacement board with the correct ROM data. If you plan to do the work yourself, consult our PCB Replacement Guide. If a simple board swap does not fix the problem, we also provide a specialized PCB Replacement Service — see the Adaptation Service page for full details.
