How do you remove all deleted files permantly?

[Spudinsp]

I was defrafmenting my hard drive and I noticed that there were files that I deleted were still there. How do I clean up my hard drive of all these files?

Empty your Recycle bin before defragging.Better still run CCleaner .

Or download and run BCwipe. It "scrubs" the hard drive. Takes forever though.
