hi i was erasing my Flash Drive just now and i saw that my HDD was in red text, i clicked it and it said S.M.A.R.T. Status: Failing. and it is telling me to back up and contact an apple person. why is it failing if it is not even 2 years old yet it is barley 1 1/2 years old (my macbook) im so confused. what caused it to "fail" and how can i fix it? or will a reboot fix this? please help ive never experienced or witnessed this. im scared lost and confused.
