The Mac HFS file system is B-Tree based.  It was notorious for losing
file info.  Pre-OS X users swore by Norton Utils and others.  Since OS
X and the Journalled HFS+ and the option of UFS lots of these problems
have gone away/changed.  Now, Norton is "bad" for OS X and most people
seem to rely on fsck.
