I appear to have developed a SATA disk error after 5+ months of use.  I was running the D at power on test daily then once a week with no problem.  Last week when running the Apple Hardware Test this error appeared "4HDD/11/40000000:SATA(0,0)".  Can anyone help me determine why this just started after 5+ months with no problems?

MacBook Pro with Retina display, OS X Mavericks (10.9)
