can i repair a failing disk on macbook pro for free? My macbook pro early 2011 says its drive is failing its S.M.A.R.T. test. It said to repair disk in recovery mode. I've attempted it twice. It doesn't seem to change the situation. 
      Could the recent installation of MacPilot  and making changes to settings be causing a problem or causing the appearance of a mock problem?
If a SMART test indicates the drive is failing [&amp; that test is accurate - you could use two independent tools to make sure they agree] then the drive is toast &amp; needs to be backed up if possible &amp; replaced immediately.

SMART is meant to warn you of imminent, potentially catastrophic, drive failure.
It is not a "fixable" problem.
