Merely a month into my MacBook AIR experience, and my HD has bitten the dust. A couple of days ago, after the security update and subsequent start-up, my AIR took FOREVER to boot. When it DID finally boot, the FINDER failed to launch. After hitting the forums I saw the .plist could be deleted via terminal, and if that was not the fix, an archive and install would be in order. The .plist delete DID NOT do the trick, so using my external superdrive, I ran disk utility with plans of archiving and installing. The message I got with disk utility was that I should try to save any information I could as my HD was failing. LITERALLY 10 seconds later, it was gone. I have purposefully taken it fairly easy on the AIR - only minimal downloading, basic iLife application usage, internet and chat, and that's about it. Frustrating to have a failure so soon. Anyone else experiencing the same? P.S. I brought the AIR to Seoul, South Korea...we'll see how many weeks it takes for repair.
