You could check what's at offset 1M for each disk. losetup --find --show --read-only --offset=$((2048*512)) /the/disk file -s /dev/loop42 If the superblock was still intact it should say ext4 or whatever your filesystem was for at least one of them. You can also try this for the disk you removed 2 month ago. If that is not the case and fsck with backup superblock also is not successful then you'll have to see if you find anything valid in the raw data.
