Hey all I've decided to sell my powerbook running 10.4 to my aunt for a nominal amount. While I trust her, there's not a ton of life left in the PB, and I'd still like to securely delete everything off of it. So, despite the time, I'm going to do a 7-pass erase, and reinstall the OS for her. However, while I've done a lot of things on a mac, I've never actually reformatted and reinstalled. It sounds like I boot off the install disk, select erase and then erase and reformat as Mac OS (journaled), correct? After this, what happens? Do I reboot the computer off of the install disk again and reinstall the OS? And on a related note, I gave my mom my old G4 tower years ago. It's running 10.2 (I think) and it is dying. Is there any way to securely delete this drive for her and for me? Would I need third-party software, or did 10.2 come with a zero-out option? I can't recall, does anyone else? I do still have all the original install disks for this computer. We have no use for this old g4 tower once my mom's stuff is off of it, so there's no need for the drive to be working after deletion. Thanks a ton!
