Alright, walk me through this. I want to format one hard drive. It is the only hard drive in the case. It has windows XP and I want to reformat the drive. You can not reformat in windows? You have to install the windows installation cd to format. I want the drive striped clean. So I insert the vista cd, praying that it will give me the option to format. It does not and begins to install vista. Step by step, how would you format this disk so that in the end, you have a brand "new" blank hard drive? Thank you so much.
