I was wondering if something like this was going to happen at some point.
SMART attributes all have a normalized value, and a threshold beyond which the drive is declared to be failing. Drive makers have been ridiculously over-optimistic about setting these thresholds. For instance, if an HDD has *any* reallocated sectors, it's going to die soon, but it won't actually say it's dying until it's reallocated a ton of sectors and is basically already dead.
