Xbox 360 S - Makes a loud buzzing noise when opening the disk tray?

I bought a second hand xbox just yesterday (matte 250gb slim model) and it seems then occasionally when i open the disk drive and the disk stops spinning, it makes a loud buzzing noise and then the disk tray opens? It sounds like the laser is getting jammed
or at lease the motor it uses to move aren't working properly, it hasn't caused any problems yet, i'd just like to know if it could do in the future... plus the buzzing is slightly annoying although it lasts no longer before the disk starts spinning or the
disk tray opens.

Buying used Xbox one

Oh yeah make sure to test out the disk drive before you buy it. Some of the launch xbox ones (including mines) had issue with the disc drive no reading and making a loud buzzing noise.

 

Disc drive makes loud whirring sound, only for Halo 4

A few weeks ago my friend kicked over my 360 while it was playing my copy of Halo 4, disc 1. A circular scratch was left on the disc, and it no longer worked in the 360, though the 360 still worked perfectly. I bought a new copy of Halo 4 but whenever I
try to play it the 360 makes a loud buzzing sound. The 360 plays all of my other games without any issues, and without the loud buzzing noise. The buzzing noise only occurs when I try to play Halo 4.

Any ideas?
