WipeDrive Utility?

Darik's Boot And Nuke is the one I use and highly recommend.

EBAN (Enterprise Boot and Nuke) is the commercially supported edition for those that require it.

Not a software solution,.. but I'm kinda partial to (although have never tried :{ ) energetic compounds in various forms: fire, explosives, thermite, corrosives and firearms.

Or for the more liability adverse, a set of screwdrivers (and an intern) will get you (or him/her) some cool round mirrors and a pair of really strong magnets.

If you heat the HDD patters to 770 °C (1418 °F) they will lose all magnetic properties. (A charcoal grill might work for that.) Data errors start cropping up at lower temperatures so sticking it in your oven might also work.

Found a link to someone actually doing some of these!

FWIW: Unless you are worried about major players (NSA, FBI, CIA, other countries equivalents or mega-corp industrial espionage) programs that overwrite the data once are enough as after that their is no way to recover the data without hardware modifications and special equipment. If you need more security than that, either you are doing something you shouldn't be (e.g. criminal) or you are a big enough player to afford going with one of the "energetic compounds" type solutions.

Here is a list of options for Windows, Mac and Unix
