I have an xbox 360 which is not flashed and that I use to go online. If I were to buy a second xbox 360 to flash, but never take online, would my unflashed xbox get banned due to hard drive swapping. I know from experience that a banned xbox gets it's hard drive corrupted and so swapping back and forth is impossible. But what about an unbanned flashed xbox? I'd like to be able to play backed up single player games offline and still keep any achievements I earn. Thanks in advance.
I dont think the hard drive has anything to do with being banned. MS reads firmware from the console, and not the hard drive. So I think you would be fine
