Erase and reinstall tiger on ibook G4
I just bought a new macbook and am planning to sell my ibook G4.
I asked the one to one trainer about erasing everything on the drive and reinstalling the Tiger OS. He suggested I just do a clean install with the tiger discs and I wanted to do some erasing first. Basically what I did so far is to go to Disc Utility and run the "erase free space" 7 times. When I returned I discovered there are still docs in the HD.
So what is the next step to prepare the machine to erase everything before selling? Is this all I have to do to rid the computer of any trace of personal info. ? Also, once the drive is reinstalled will it be prompting me to sign in again as me and then I can check if everything is new?
Thanks
