Hi, hopefully someone can help me. The past few days, my Macbook Pro has been acting up recently and then today I ran an extended test on my Mac. Unfortunately when the test was over, an error came up "4HDD/30/40000005:SATA(0,0)". I looked online and saw that it was a hard drive malfunction. I don't see how this is possible because of how young my Mac is: A Mid-2012 Model, 13 inch, got it for Christmas 2012. I'm thinking of going to my nearest Apple store and see if they can fix it because I am still under the one year limited warranty, but hopefully someone can tell me other solutions. I've tried resetting the computer, but that makes it worst and it's an absolute pain when I do try to reset it. Any thoughts?
