Seagate IDE 3.5" PCB - ST3320820A (9BJ03G-500, 3.AAC, 100436212 E)

This sale is for the hard drive circuit board (PCB / logic board) ONLY — no hard drive included. Product ID: ST3320820A, 9BJ03G-500, 3.AAC, 100436212 E. Because we stock a large number of PCBs, the exact board you receive may vary slightly from the photo. Intended use: data recovery and hard drive repair. Prior to purchasing, run our hard drive diagnostics guide to confirm that replacing the PCB will resolve your issue, and verify part compatibility using the Donor Matching Guide. Note: most Seagate IDE 3.5 PCBs contain critical, unique information stored in a ROM memory chip; that ROM data is required for the drive to operate correctly. The ROM chip or its contents must be transferred or reprogrammed onto the replacement board. If transferring the chip is possible, a local computer repair technician can typically perform the transplant. For orders of $60 or more we include a complimentary adaptation service, which covers either moving the ROM chip onto the new PCB or reprogramming the replacement with the correct ROM data. If you plan to perform the swap yourself, review our PCB Replacement Guide first. Should a simple PCB swap not cure the problem, we also offer a comprehensive PCB Replacement Service — see the Adaptation Service page for full details.
