Your best bet it to take the three drives that are mostly like to be mostly correct, which also certainly excludes the one that resync was happening on, and recreate the array. e.g. mdadm -C /dev/md0 -l5 -n4 -c ?? /dev/sda /dev/sdb missing /dev/sdd but make sure you specify the chunksize as a number, and make sure you get the device order and positioning right. Then mount the filesystem read-only. Then - when you have your new drives - copy the data off. Don't trigger a resync. Don't do a fsck. These are likely to hit a bad block and hurt you. Good luck.
