Well guys, the first MAJOR issue I've ever found on my mid-2011 MBP, and I know this is something everybody will most likely encounter at some point. I went to upgrade to Yosemite, and it told me S.M.A.R.T. had encountered problems and was failing, or however the message goes. I checked my disk utilities and lo and behold, my drive is failing. I downloaded the trial version of SMART Utility and got a more detailed report, I have a bad sector. I do not know if the damage to my sector is soft or hard, fixable or not. Disk Utility says the problem cannot be fixed. What steps should I take in attempting to fix it? and if indeed it cannot be fixed, can you please help in picking out a new harddrive? I'm not sure if I'm still covered under warrant at this point, I did have Apple do one fix a year ago under warranty. I do have somebody skilled enough to do the repair if I just bought a new drive. Thank you all very much.
