recently my friends ps3 broke and hes considering buying a new one except hes afraid of losing all hes saves music and movies so i was wondering if i took the hard drive out of his ps3 and put it in mine would i be able to copy his files onto a usb flash and give it to him to copy back onto his new ps3 or would i just get a message asking me to format the hard drive the second i start up my ps3 with the other hard drive in it?
