I had the exact same problem. It is the hard rive after all. The emulation portion of your hard drive is most likely corrupt...you know, those 6 gigs that somehow get taken up for no real reason.
You can try reseting the hard drive cache...there is a guide on how to do that and it sometimes helps. Google xbox 1 games will not play on xbox 360. If that doesn't help, you need a new hard rive to play xbox 1 games. Sorry.
