I just recently purchased the new super slim 500gb model, and transferred everything from my regular slim to it via ethernet cable. Now I find myself not liking the new super slim. (It can't run games properly, parts of Mass Effect 3 were unplayable.) So what I'm aiming to do is simply switch the hard drives of the two PS3s so that the older slim has the 500gb hard drive. I read online that I would need to format it or something, but I don't want to delete everything on the 500gb hard drive. So how should I go about doing this?
