yeah because when I play xbox games I throw my xbox around
All it takes is one small tilt or bump. It could be from a slamming door, someone walking too heavy, something dropping to the floor heavy enough to vibrate the system, a small earthquake, or if you live in a tall building it can sway back and forth in the wind.
There is no disc balancer in a 360, nothing to keep the disc level with the laser, so if there's ANY movement of the system at all while that disc is spinning, it can be scratched.
Any movement that causes it to no longer be level to be more precise. Some movement actually is fine and won't cause any problem because the console itself remains level, which is key. The console just has to remain level while a disc is being used.
For instance, if your console is on a TV cart, that can be pushed while playing the disc. I have tested this myself. As long as I'm careful to ensure the way is clear so the cart moves across a clean floor and move it slowly, it's fine. Is it safer to just turn the console off and unplug it when moving? Most definitely. Or also to just remove the disc.
Two things that are very bad to do with a console is to place it on the floor or on top of something like a large speaker or subwoofer. The console will be more prone to movement due to vibrations there. A stable shelf is far safer, and in a horizontal position when possible. That gives it a better center of gravity and makes the chances of it not remaining level become very low.
You'd be surprised what can cause a scratch. Anything from the tiniest fraction of movement when the disc is in motion, to the brush of a fingertip. Scratches are - in most cases - classed as accidental damage, and Microsoft wouldn't do anything to help you.
Only thing they really can do is offer a disc replacement program for games they publish. That is better than buying the game again for newer games that haven't had a price drop. If it's not published by Microsoft, then you have to ask the publisher if they offer one. Most of them have something that will allow you to replace the discs only in the game for about $20.
uh I paid 20 for the game that is scratched, and what is the purpose of replacing it if its just going to get scratched again ? I can tell it was made by the xbox because it's a circle scratch, but only about half a circle which means it only hit the disc for a fraction of a second or whatever. My xbox is perfectly flat on a table. if a fly landed on the table can cause the disc to go off balance that's a defect
