It may be that SpinRite could fix that by forcing a remap. Another option -- which I didn't mention because it probably isn't an option for the original poster, but which may work with your servers -- is that some high-end RAID systems can do something like SpinRite at level 4+, as can ZFS. They call it resilvering. I don't think these systems do statistical reconstruction, but periodic read-then-rewrite can stave off the need to reconstruct.
