1st Gen. MacBook Air, 1.6, 80gb HD. 31 months old. Hey folks, in the last day or two my MBA has started making a clicking, fluttering sound. I thought it might have been the fan, either dust or lint build up. Popped the bottom off, cleaned the fan, and the sound is still there. While holding it over my head, I noticed that the sound seems to be coming from the area of the hard drive. Here's a recording- http://dl.dropbox.com/u/13942518/Hard_Drive_Sounds.m4a I use Time Machine, and nightly full Carbon Copy backups, so I'm not too worried about data loss. Just wondering if I should make a Genius appt. ASAP, or if this will wait for a bit. Thanks.
