None of the your values are exceeding the threshold - it works = backwards. If the value is LOWER than the threshold, you might be in = trouble. Also, judging by the raw read error rate, seek error rate and hardward = ECC recovered, allow me to guess that this is a Seagate drive. :-) (Seagate drives, perhaps among others, use these raw values way = differently than others. My Hitachi 7K1000.B has 0 on those.) Regards, Thomas=
