Darik's Boot and Nuke
Great for bulk cleaning of hard disks
Pros & Cons:
Darik's Boot and Nuke (DBAN) is somewhat a different alternative for deleting files on a hard drive.
It's used to construct a floppy disk or CD that will automatically wipe the hard drives of any PC that's booted from the disk. It's great for bulk disk cleaning of PCs, and is also useful as an emergency tool for quickly removing sensitive information.
However, the power of this app makes it a dangerous tool in the hands of beginners.
