When I eject(or safely remove) or unplug my mp3player from the USB, the screen freezes and an "ok to disconnect" message remains on its screen. Then I have to reset my mp3player. However when I shutdown my computer while the my3player is mounted it doesn't freeze and everything works correctly. I know this is a problem with my mp3player. The question is how can I eject my mp3player normally without forcing to shutdown the computer?
