System Rescue CD

Knoppix is often touted as a good choice for using as a bootable rescue disc. There's nothing wrong for using it as such but a more specialized live CD is available. Strangely enough, it's called System Rescue CD. A complete list of the tools available on the CD is available on the project's home page.

One tool found on the System Rescue CD which I've used in the past is Darik's Boot and Nuke. If you select DBAN at the boot prompt, you'll boot into a very specialized live Linux system which allows you to securely erase the contents of a hard drive by overwriting it repeatedly with other data. (Merely reformatting a hard drive does not erase existing data.) DBAN is especially useful for companies or individuals decommissioning and selling off or donating old PCs. They can be booted into DBAN, the drives wiped, and then the you don't need to worry about confidential data being disclosed.
