Like I used to tell the users of PS2ESDL: Don't ever use the Windows defragmenter. Don't ever use Power Defragmenter either since both of these defragmenters won't fully defragment the games. Sometimes they do, but there are times whereby they will report 0% fragmentation, when there is actually file fragmentation.
