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.
