I realize no one knows with 100% certainty... As you already said, nobody knows with 100% certainty. In the failures I've experienced I'd expect it to start catching errors within a few days. However, on those drives the relocated sector count never increases, which suggests that the firmware never relocated those sectors when overwritten, which seems brain-dead to me. If the drive relocates the sectors, then conceivably it could go quite a long time until having errors, probably in an entirely different set of sectors. Even if it doesn't relocate, the reliability of the bad sectors could be high or low. Rich
