Since you are sure it is ext3, then you should use "fsck.ext3 -y" to fix it. I usually try that operation first with "-n" instead of "-y", but your mount attempts show that the "-n" would be superfluous. If fsck scrambles that volume worse, then you'll have to recopy from your backups and redo the forced assembly. Or try with the other two disks.
