Yes, but bad block remapping may make it so that the drive continues to
provide service after rebuilding the array.  I'd consider replacing the
drive if this was a production server, if it was a personal server I'd
probably just remove it from the array, run a "badblocks" on the partition
in question in read/write mode, and then add it back in if it's clean.
badblocks can exercise the drive and cause badblock remapping to do it's
thing.  If no bad blocks are reported, it may be fine to leave in service.
