I want to format my hard drive on my laptop. I don't need most of the programs or files and have copied anything I need. I primarily use it only to surf the web or to connect to my pc at work using logmein.com. I open My Computer and click on the "C" drive, than go to File\Format. It keeps telling me it can't do it becuase other applications are using the drive. I have nothing running and clicked off everything in my system tray.
