Whenever I have had an old drive with previous data or OS on it that I don't want anymore, I have always been satisfied to simply install windows on that drive, using the windows installer to re-partition and format the drive during the installation.
In another thread someone was talking about wiping a drive with dban before installing windows on it, perhaps suggesting (or not?) that this was a good practice.
I like using best practices so, my question is, what benefit, if any, is there to using something like dban to wipe a previously used disk before you install windows on it?
The only thing I can think of is if it was a second hand disk you got/bought from someone else, or if your old drive had data you want to make sure cannot be recovered. If that's all it is then I get it, and if I had those scenarios it would already be my practice to do that (I have never had those scenarios though).
But is there some other good reason to do it that I haven't thought of?
