"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Boot into the Recovery Partition by booting while holding down Command-R, then open Disk Utility.

Click on "First Aid" tab, then click on the drive icon on the left and check to make sure the S.M.A.R.T. drive status at the bottom right is shown as "verified".  Then run Repair Disk.
