Problem with my S.M.A.R.T status
Do you have any idea that can I do when my S.M.A.R.T status is unconfirmed?
MacBook Air, Mac OS X (10.6.8)
Based on this article, I would guess you have a hardware failure coming soon.

Therefore, I recommend you visit an Apple Store or Authorized Apple Service Provider very soon to have an assessment and receive some advice on next steps.
