I was thinking that you wold be using 'badblocks' directly rather then via fsck, and was suggesting badblocks -n /dev/sda3 & badblocks /dev/sdb3 & badblocks /dev/sdd3 .... Running 'badblocks' across a raid5 array isn't a good idea, as if there are any bad block, the devices will be kicked from the array, and the test will abort.
