Steps for zeroing data:

These steps assume you have a Mac OS X 10.2.3 or later CD:

1. Insert the Mac OS X CD.
2. Restart the computer.
3. Immediately after the startup sound, press and hold the "C" key to start up from CD.
4. When the Installer screen appears, do not click Continue. Instead, choose Installer > Open Disk Utilities.
5. Select the hard drive to erase.
6. Click the Erase tab.
7. Select the volume format from the Volume Format pop-up menu.
8. Click Options.
9. Select the checkbox for "Zero all data".
10. Click OK.
11. Click Erase.

There is Kill Disc available free here

http://www.killdisk.com/downloadfree.htm

Which can be used to just wipe a partition or more if required and then if you want to be very sure that your data is destroyed Boot & Nuke from Darik's is available here

http://www.dban.org/download

Which can be set to run multiple Wipes writing Zero's to every sector and is the Accepted way of Destroying all Data.

However using either of the above will require that you have the Install Media available to reload your system.

While it is still possible to recover Data it would require a Forensic Recovery to be used which will result in the destruction of the HDD and costs quite a lot of money. These Recovery methods I have only seen used by Government Agencies involved in Policing because of their cost.
