I'm trying to run the firmware update Seagate Barracuda ST500DM002/ST320DM000/ST250DM000 Firmware Update. But when I run the tool, it does not detect my USB thumb drive. In fact it doesn't detect any of my USB thumb drives. Even formatting the thumb drives does not change the outcome. Is there a special way or maybe a setting I'm forgetting to get the tool to detect any USB thumb drive so I can run this update?
