I want to upgrade my HDD for the ps3, but I don't really know anything about it. I know there are videos showing how to change it, so im not "really" concerned about tht at all. I dont know what kind to get, or what to do once i change it. Does the operating system remain in the system? How can i save my games that are already on the ps3 to something so i dont lose them? also the ps2 memory cards i've created? what do i do? thankstonyandsteff
