You have another issue here though, it looks like your "few" attempts have

rid of them all, you should only have [1] /dev/md0 for your raid 5, not 3.
Well - 0.9 superblock is 4K at 64K boundary, at least 64K from the end
of the device, but less 128K (man 4 md). If a filesystem on some
partition taking up that space *didn't* overwrite this space with its
[meta]data (check with debugfs, xfs_db, etc.), just clean it up
*carefully* with dd or hexeditor.
