I don't know too much but I may be able to help. I started by closing all applications and then plugged the USB into the port. A few moments later a window opened and when I right clicked it allowed me to make a shortcut to the desktop. The Verbatim icon is now on the desktop and I can click it and it opens. I have Windows Vista and can also open the "computer" option and the hard drive is there - mine shows as drive "f". I hope this helps. I am a good user of the computer but a novice at installing, un-installing, etc.
