Great tool for a secure deletion of sensitive data on a hard disk or also USB stick. I personally like the "ProtectStar Secure Deletion Algorithm" that runs through fifty erasure routines, and is completely integrated into this security solution. The activation process is not easy, but the support helps excellent.

Pros: - Very good tool for a secure deleting of files and free space - great support - great performance Cons: Doesn't work at Windows Vista at the moment
