my disk utility says that my hard disk has a "Failing" S.M.A.R.T. status in red letters, is there any way or is it possible to restore it back to normal? can someone explain what it means and is it inevitable that it will fail? when it fails does it mean it's crashed and is the data recoverable? what are ur advice? should i back up immediately and about how long of its life has it got do u reckon? thanks for any help in advanced.
