I think I'm going to format my hard drive to delete everything from it and start fresh with leopard. I already have leopard installed, but I think I should just format my hard drive (after backing up what I truly need like my music and other files) and then just install leopard. Question, I have read that I go to disk utility to do this (format and install leopard), is this correct? If so, what else do I need to know before I do this? thanks!
