My U3 Drive used to work fine, but now it doesn't at all. When I used to plug it in it would pop up a message saying it needed to disconnect from my computer before it could run properly. When I hit ok it woulb open the launchpad. Now instead it opens a blank folder from within the U3 drive. PLEASE HELP, I need to be able to use this drive. It works fine on other computers. This comp is connected to a network and I do not have administrative rights.
