Hi guys, have a question. Hope can get some useful feedback from you guys.

Can I swap between 2 hdd for 1 ps3?

For example, my friend and I share a ps3, so he has his own hdd and I have my own hdd. So when he plays he swap his hdd in and then all his games saves and account and dlc or whatever it is will be there. And when i get the ps3 and plug in my HDD, then all my contents will be there. Is that possible?

Or will the ps3 ask to format my hdd when we swap another new hdd in and put back the one that was there before?
