The metadata information from the drive may be inaccurate because the
log is corrupted. Then some folder data may have been lost and prevent
you from recovering the files that are in some folders.

After you're done copying all files you can from the disk, you can try
to make a mirror image on another drive at least as big as this one,
and run xfs_repair on the image. After that you could eventually get
more data back (it depends upon the extent of the damage to the actual
data and file structure).

To copy the disk on another one, you can use ddrescue or dd with
"noerror" option.
