And if that doesn't work then you can use dd_rescue to copy the data to
another harddisk and store the list of bad blocks on-the-fly.

If you need to know which files are damaged, in many cases you can later
use that bad block list to retrieve the file list with
debug / administrative tools for particular file system.
