I don't use the raw format command unless I badly need it.
I have used Drive Image2002 to create a image of my C: Drive. I created the image after installing all the software drivers etc, So the time when I feel my C: Drive is full of crap...I simply restore it from the image I have made ,stored in my Backup Partition(BTW I have made CD's of the image too just for backup) .So the system becomes as good as new....Also saves the time of Installin windows from scratch....The image gets restored say within 7mins...
must faster then a scratch install
