Sometimes you need to quickly destroy all your data, for whatever reason. In this case Darik’s Boot And Nuke bootable CD can help. What you need to do is download the file image dban-2.2.6_i586.iso (last version 2.2.6) and burn it without unzipping. Then to deploy it, simply reboot and follow the prompts. Important to mention, that in your PC BIOS booting order must be set to start from DVD(CD)-ROM. Beware though, as this program is designed to look for any hard drives, not only the system one, and to wipe out everything without any possibility to restore. Therefore, be extremely careful with that CD. DBAN is a good way to recycle your old computer, making sure that no identity theft is possible if you sell your PC, for instance. It is also a good way to totally sanitize your hard drive before new Windows (or whatever OS) installation, especially if you suspect it was compromised with virus or rootkit infection. Creator of this tool claims that “DBAN prevents or thoroughly hinders all known techniques of hard disk forensic analysis.” It is free to use. Just be aware that good cleaning of large volume of data takes time.
