Carefully pry open the plastic outer casing of your USB drive using a flat pry tool to expose the green printed circuit board (PCB).

The tool cannot sync both memory channels. Force inside the Flash Type tab settings. 00000 No FID / Device Disconnect

For the technically inclined, FA00 and especially FA04 can be physical.
