Formatting a G5 and leaving it empty

I would imagine this would work?

Mount the G5's HDD using Firewire target disk mode on a different mac. Then use disk utility on the other mac to format the mounted G5's HDD.

 

it even would work with a usb enclosure , for pure formatting there is no need for a firewire enclosure , erase/ format the hdd in apple extended journaled and then put it back in the g5 and its ready for the new owner to install the operating system he likes

 

Insert the Install-DVD, power it on while holding the "C"-key on the keyboard, select your language, choose Utils->Disk Utility from the top-menu, select your hard drive and click "Delete".

Don't have access to any Install-DVD? Burn yourself an Ubuntu-LiveCD or something, then do

Code:

sudo cat /dev/null > /dev/sda

in the Terminal.

This overwrites the whole disk with zeros. Do it a couple of times and your data cannot be restored again.

 

Thats the easiest idea it doesn't require anything but a blank CD-R

 

Code:

dd if=/dev/urandom of=/dev/sda bs=1M

Tinfoil hat.

 

just remove the hdd and give it away like that. New hard drives are so cheap anyways.
