personally I use fdisk off a live OS USB stick.
But I wouldn't recommend that to your average user.
I will let one of the more current Admins tell you the difference between quick and none quick format in the windows enviroment.
Personally after a bit of a bitch of a virus to get rid of my personal method of reinstalling is.
Live OS boot.
fdisk
Single pass of shred
reinstall the OS
I will fully agree it is over kill!!!! I don't care it works for me.
