I just received MW2 and went to install on HDD.
The console was making an odd buzzing sound when starting up, even during game play, so I heard installing on the hdd will resolve the issue. Upon installation, at 7% it shows that the game can't install, and to clean disc or try again. There are no scratches or smudges on the disc at all.
All other games played before this worked fine. No noise whatsoever. I was wondering if anyone had the same issue.
I had my 360 Slim for a month now. Had another many years ago that suffered from the Red Ring. Been years since a 360 been up in this household and now I have the slim.
I was told installing will resolve the buzzing, for it will load smoother and faster. I suppose the disc doesn't run but validates the game to avoid piracy. Also that not running the disc like that avoids over heating and perhaps reduces wear and tear of the console.
