Is it save to buy a 4 Gig Memory Unit or will this be "banned" with the next update by MS? I want to put my savegames and bought XBLA Games from the 120 GB HDD of my friend to my private new one and thats why I'm asking this is maybe stupid question, but I think you guiys here have the knowledge to make this happen. On my new HDD is a Forza3 Savegame. Also I cloned the 120Gig from my friend and put all the data on my box. Problem is that the downloaded songs from RockBand and so on won't work. These songs were downloaded to my friends account and we want to play them here and at his house sometimes. Is this even possible or can I delete all of these data?
