Usually when you get the scandisk has to restart, it means there's disk activity (scandisk can't safely run while there are reads and writes to the drive). There's two ways to remedy this: disable any background processes (check your system tray). The other way is to do it from DOS (my preferred way). When you boot, press F8 and pick boot into the command prompt only. Then type
scandisk c:
When you're done, press ctrl-alt-del to restart.
