using old hard drive for new computer, how to wipe the hard drive?
I want to use my old hard drive for my new computer. I'm building a new computer, yet, I do not want to spend the money to get a new hard drive, so I'd like to install my new windows 7 on it which was previously used for my old windows 7. I've heard that dban is a good tool for wiping the drive and I wonder if I use the quick erase where it writes over it once if that will be good enough for me to install my new windows, or do I have to write over it 3 times or more, which I would like to avoid so as not to shorten the life-time of my hard drive and so that it doesn't take 5 days. Thank you for any help.
