WhiteCanyon provides software to really, truly, honestly remove all the data on hard drives so it cannot be recovered. As Paul points out, we could download free tools from the internet, but "they don't get certified for a reason - they don't work." WipeDrive can erase one drive at a time, a dozen at a time, or even build a PXE network.
In addition to securing old hard drives, WipeDrive makes it easy to recycle systems to keep them out of the land fill and help not-for-profit associations with donated hardware. The program also gives you great reports that can be shared as proof that hard drives have been wiped clean.
