I already put it in my xbox and it reformatted and seems to work fine. I'm using Vista. I go to device manager, click update and I got to the Actionreplay/Xbox/drivers and click next, and it says "The best driver for your device is already installed" and under that it says "Windows has determined the driver software for your device is up to date." I've tried to uninstall the drivers, and it just automatically reinstalls them. I'm guessing this section is pretty empty anymore, but if anyone could help I'd appreciate it a lot.
