Discs occasionally bump into something when I try putting them in?

bumping is strategic. you know where to bump when you play with damage. it's much more realistic. however, they SLAM you on multiplayer. several achievements are in multiplayer, but i'll never even try to get them unless they put a damage on mode....quiet
a bummer.

For me this just adds to the competition. Early on I was to bumping into other people, but realized that if I were to play with assists off that my car would not last. Trying to clean up my act so to speak. A little rubbing is okay, and I do have the occasional
bump into another car. I agree that some races need more laps because everybody crowds to the corner to gain an edge. Lately I've been trying to take them on the outside.

If you could install games and play without the disc even law abiding citizens would abuse it.

Borrow or rent a disc, install it then get the game for free. Developers and publishers would go bankrupt and there would be no more games being made.

As for needing to backup. Just look after your discs. Put them back in the case when not using them. My games I had 9 years ago when 360 first launched still work and have no scratches. I even have games for the original xbox that are over 10 years old I
still play occasionally and they work fine..

Take a disc from Season 1 or 2. Try and play something that you know is not on that disc...so it prompts you do put in another disc...put in Season 3 disc and it works for no reason whatsoever.

I don't mean the sound of the disc spinning under normal circumstances, which is what you're describing. For example, occasionally when I shut down my console, the disc starts to spin extremely fast - way faster than it ever would when playing/installing
a game - and the only way to stop it is to turn the console back on and then off again, or to press eject. The same thing happens occasionally when exiting the avatar editor. The disc drive spins at a crazy speed and the only way to stop it is to eject the
disc, then close the tray again. The drive only spins at up to 12X during normal use, but this literally sounds like it's spinning at 50X or something and considering when it happens, it's definitely a bug of some kind.
