This will only work if the alternate superblock has the correct
and intact inode information, which might still be the case after
a background fsck went "too far". Then fsck should be able to
correct the inconsistencies, and a lost+found/ directory will
be created at the top of the file system's hierarchy which
will usually contain all files in their original directory
structure, but with the top level names replaced by inode
numbers; from the content, you can often recreate those names.
