Bottom on macbook pro makes cracking noise when pressures applied.

The noise occurs when the pressure is applied right under the disk drive. I haven't noticed any technical issues with my computer, but the noise made me concerned, so i figured i should post on what i should do about it.

Check bottom cover. There are two lock which hold down the cover. Maybe the cover is not attached to the lock.
