I have a 4GB Xbox 360 slim and I bought a 500GB hard drive for it. I pushed the hard drive in its place and after I heard that click, I pushed it a little bit more to be shure that it's in place. I noticed that the hard drive bracket (the slide that holds the hard drive) it's elastic: after the hard drive is inserted, it wobbles (maybe to prevent hdd damage when the xbox is moved).

My question is: how does the hard drive bracket work? is there a metal spring in its mechanism that allows it to wobble? Did I make any damage to it because I pushed the hard drive to be sure that it is in place? I don't want to teardwon my console to find that out.

Thank you!
