I have an external HD formatted to default HFS (Mac OS Extended - Journaled) and very once and a while I get a folder called DamagedFiles in the root of the volume. The folder contains a collection of links to files on the drive. In general the files seem fine as I am for example able to open the images or text files without a problem.
Is this serious? What can I do to fix this problem? Any advice would be great as I couldn't find anything on here or via Google that addressed this problem in particular.
