Hey guys, here's the situation:

I have an 80GB PS3, with a 500GB hard drive in it. This is on 3.55 kmew, or something, I think. I've not touched it since the 'scene' properly kicked off. I also have a 250GB Slim, with stock firmware.

Honestly, I jailbroke my PS3 for the wrong reasons. However, with PS+ and a lack of time, I don't really care about it any more. However, I'd like to hold on to it, just in case.

How easy is it to swap the hard drives? I know they have to be formatted, and on the slim that's fine. With the 250 in the old one, though, will that be a pain to do? I'll have to reinstall the JB right?
