Alienware 14 CD Drive sound normal?? Clicking and buzzing.

I recently bought an Alienware 14 for my wife and whenever she uses the CD drive it sounds much louder than the drive on my 18, its only when inserting and removing the disc, sounds like a buzzing then multiple clicking sounds, it when the disc is spinning it sounds fine and it happens with all discs we've tried, also the clicking is so loud you can feel it against your leg when its on your lap. Has anyone else experienced this with their 14? Is this normal or is something wrong? I have never had any of this with the drive on my 18 so I am concerned something might be wrong and if it is I want to try to deal with it while I can still return it if necessary since I know how horrible there tech support is. Thank you.
