My flash drive doesn't work with your computer system. It uses U3 software. Your system only recognizes 1 drive as the one that has the software. My drive creates to virtual drives for example E: for software and F: for documents.
In order to keep our public computers secure and running smoothly, we do not allow any software to be uploaded or downloaded onto our network. This includes the U3 software on your flash drive. Opening our network up to outside software creates a potential for computer disasters, and isn't a risk we are willing to take.
