Clearing Mac without factory discs

[VAMOS DAN]

Hi guys iv sold my mac mini to a relative (its redundant now as ive got an iMac)

Im not sure i have the orignal setup discs to reformat the HDD so just wondered if anyone can give me any steps on how to wipe any sensitive info off of it?

I have software on there which i paid for ie Ripit Toast etc so may aswell leave these on there for them

any advice is much appreciated

either zero out your hard drive or do the much longer 7 pass erase, explained here:

shouldn't be a problem

OS X can take up space, I believe Leopard +ilife can take up to anyway between 17-20GB of space (Snow Leopard about 5-7GB less than that) and any other software you may have etc
