Hi, My computer's a Mac Mini Core 2 Duo 1.83GHz upgraded to 500GB HD and 4GB RAM. I think at one point (probably when I switched from my 80GB to my 500GB drive) I screwed up and made the partition format on my drive Apple Partition Format. As I was just doing disk cloning, Leopard had no problem with this, and never mentioned anything being wrong (if it did I could have fixed it back then). However now, when I try to upgrade to Snow Leopard, it complains about this, telling me I can't upgrade and my only real option is to back up my data and fresh install. Problem being, I don't have a 500GB drive laying around, and I don't have the money to buy a 500GB drive to use once to back up all my data. It pisses me off to no end that Leopard didn't complain about this when I first did it if it was going to be a problem in the future (back when I could have fixed it) and only now it's become a problem. I guess my question is, is there any way I can get by this problem and install Snow Leopard? Or am I gonna have to wait till my friend needs to wipe his PC again and borrow his HD for a night?
