Here is the S.M.A.R.T data from hd tune. Is my hardrive healthy? I've only had it for a few months and some things are highlighted. I also noticed the Raw read error rate is pretty high. Is my hard drive slowly dying?
As for the highlighted attributes, they are perfect. The reason that HD Tune has picked them out is that it blindly thinks that any attribute whose normalised value is close to the threshold is suspicious.
