I have been having on going problems with a Seagate Free Agent go 500 GB external USB drive and pretty much any computer that it is attached to. This is the second drive that I have had after having the first one replaced I seem to be having the same or similar problems. Basically the drive was working fine and then it basically over night everything went wrong. When hooked up I cannot operate any software, remove the drive, check disk management or reboot the system. I cannot boot the system with the drive attached, it stalls. I cannot even safely remove the drive without forcing the computer to shut down with the power button, as soon as the drive is no longer attached all programs immediately respond like nothing ever happened. I have seen similar situations described on several different boards but no one seems to have any solutions. Any help would be appreciated.
