I have a 10 gig hard drive that has my 10.2.4 system on it with tons of files, I want to install a 40 gig hard drive and move everything to it, what's the best way to do this to make sure everything works okay, with permissions etc it can get scary, I am guessing I have to use a utility to make an image of the drive or something but have never done this so am not sure as to the process, thanks!
