Seagate ST3320418AS 9SL14C-022 HP35 5701 U SATA 3.5 PCB (Logic Board)

This sale is for the hard drive circuit board (PCB / logic board) ONLY — no hard drive is included. We stock these PCBs in large quantities, so the exact board you receive may differ slightly from the pictured unit. Compatible with Seagate ST3320418AS (9SL14C-022, HP35, 5701 U) SATA 3.5 applications and intended for use in data recovery or drive repair. Before purchasing, confirm compatibility by reviewing our Donor Matching Guide and run the hard drive diagnostics guide to verify that a replacement PCB will resolve your problem. Important: most Seagate PCBs contain a unique ROM "memory" chip that holds critical drive parameters required for proper operation. You must transfer the ROM chip or its ROM data onto the replacement board. If you cannot perform this yourself, a local computer technician can usually move the chip. For customers spending $60 or more, we provide 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 do the work yourself, consult our PCB Replacement Guide first. In cases where replacing the circuit board alone does not fix the drive, we offer a specialized PCB Replacement Service — see the Adaptation Service page for more information.
