While some of my clients (certain DoD contractors, Federal Reserve Bank) required the use of a metal shredder to take care of the hard drives, Kill Disk ( http://www.killdisk.com/ ) has a free product that is perfectly secure for most people. If you need a more secure erase of the data, you can buy their DoD certified version, which does multiple writes over every block on the hard drive (the free version only does a single write over every block).

The way to make the contents of your hard drive disappear forever is to mail it, postage paid, with no return address, to:
The Most Honest Member of Congress
The US Capitol
Washington, DC 20510
It will never be seen again.
It takes a lot to truly overwrite data on a disk and that trick requires random overwriting each individual bit multiple times to prevent someone with the time, know-how and right equipment from breaking through and reading the data on a HDD. If you don’t have the time, stick with physical destruction.
