</div>I have never yet seen smart tell me a drive was bad or going bad at<br>
work where I have over 100 drives and I have replaced > 20 bad drives<br>
in the last 10 years. More would have been bad but drives usually get<br>
replaced when their size gets too small to be worth the 10W so so they<br>
consume at idle. Usually I find bad (or going bad) drives by the<br>
machine locking up or the drive getting kicked out of a raid 5 or 6<br>
array. And when it gets kicked out of an array I run badblocks for a<br>
weekend on the drive and if it finds 1 single bad block I RMA the<br>
drive since modern hard drives should automatically remap bad sectors<br>
to good ones they have in reserve. If you see any bad sectors then<br>
something really bad is happening..<br>
