Can anyone tell me how to wipe the hard disk of an apple iBook?

[frogs]

Dh wants to flog off his old iBook, but obviously not without making sure there's no identifiable information on it.

Does anyone know how to wipe the hard disk completely? As an added bonus, the screen only works intermittently and is very distorted and headache-inducing, so the easier this is to do, the better.

Straight copy and paste of an answer to this question from the Geeky stuff forum.

tucows.com is a good site if you're looking for shareware or freeware software, for all platforms.

Copied from the last post I made on this subject.

For total security, remove your computer's hard drive, hit it very hard with a brick, several times, then burn it.

Or buy a commercial product like WipeDrive which takes a long time to utterly blank your HD.

Or download a free one. This is the first one I found on Google, so I've no idea if it's any good.
Eraser

My personal preference would be to go for the freeware. But I'm cheap like that.
