Repetitive clicking noise on SSD Macbook Air
Recently, I opened my computer to hear a "rat-a-tat-tat" sound occurring for about 1 second, repeating every 4 seconds.
I searched the Web and came across a video posted on Youtube of someone who speaks in a foreign language, but is experiencing the EXACT same clicking sound, here is that video: http://www.youtube.com/watch?v=9bPrCCujLJ4 - best rendition of the sound is around :46 and :57 into the video.
This is a 13" SSD Macbook Air - there is no hard drive in this unit. Any ideas on what is causing this sound and how best to resolve it? It's really annoying. Thanks.
MacBook Air, Mac OS X (10.7)
