Problem with Disk tray

My 360 does this but it doesn't seem to be a problem. I've pulled my 360 apart to fix RROD and there was nothing wrong with the disk tray. It may be the laser moving to position to the fact that the xbone has a non-front loading disk tray and it's been upgraded
to a push slot disk tray. Saying that the grind noise may be the disk spinning device holding the disk in place

here is the official disk tray support page:

Hope your questions are answered.

Does it still do the same if you remove the front face panel? If so, then I'm afraid you will have to get it repaired, or replaced. They are the only options available to you with that kind of hardware based fault.

Firstly, Welcome to Xbox Forum Support

As for your problem, it's only normal if there's something touching the button the whole time (a cloth maybe?), but I'm figuring that's not the case. It sounds defective, I would suggest taking it back to the place you bought it, or give Microsoft a call
and request a new console.

If you are having trouble with a cd,dvd or a game not reading or damage to a disc try these steps in order:
