I would obtain a replacement drive for sde and use gnu ddrescue (dd with error
retries) to create an image on a reliable drive. Then re-create the array using
the replaced sde instead of sdd. You should have more luck that way.
If you still have fsck issues then I'd suggest that the futzing around may have
caused corruption.
