I want to re-install panther with a fresh install to free up disk space and to hopefully get rid of quite a few errors i'm getting. how do i backup my stuff? do i just copy my whole user folder to my ipod? do i need to copy anything else? application folder? library? once ive backed up my files, then what do i do from there? do i go in disk utility and erase my HD completly? can someone guide me through this process?
