This link gives you the correlation between hard drive diagnostics and actual failure - kinda appropriate for me given I have a hard drive giving hard read errors and a rising raw error count. Turns out read errors, even hard ones, have little correlation to imminent drive death. The uncorrected error count though is amazing - as soon as it goes from zero to one your drive has a 70% chance of dying this next year! Kinda feel like checking all my drives now ...
