I was planning on putting a new hard drive in my friends 233 mhz iMac. Since it only has a 4 Gig hard drive, more room is needed and externals are little pricy. Probably going to put a 40-80 gig hd in. How do you partition it, i read that if the hard drive is bigger then 4 gigs you have to partition it. I'm going to put 10.1 on it. So, anyone know how to do this?
