It's frustrating because a simple "if hard read errors > 0 || failed self tests > 0 then drive = not okay" would have meant I could just read the SMART health indicator and eject the drive from the array (or whatever it belonged to).
IIRC from heterogeneous disks in an array I had once, I was getting 10* the number of errors on one pair of disks from the other pair. It turned out that seagate was reporting uncorrectable errors and WD was reporting all errors -- the seagate had an extra field where it reported the raw error rate. If you are gonna script a "not okay" heuristic, be careful not to overgeneralize from one vendor to the next.
