I have an usb drive that doesn't show up in "my computer", the first time i plugged it in it worked, i stopped using it for a while and started working, but as soon as i plugged it out and in again it stopped showing up. When i plug or unplug it it makes the sound, it showes up in "printers and devices", when i click on "browse files" it shows the letter of the disk which i can't click.
