My MacBook Pro is making this strange sound(example below). It is coming from the front of the laptop. I do not think it is the hard drive because the hard drive is in the back of the computer. Although, I may have the exact location of the sound wrong. Also, I have opened the panel to check for debris but there was none in there, so I do not know what is causing this sound.
