On this one I have about 39% free space- 3GB out of 8GB. After having run the program more than a dozen times I still have 35 fragmented files (1.7GB) in 779 total fragments, 35% fragmentation. This is on an old W2K box running the old version of defrag, ver 1.21, since that seems to be the most recent version capable of running on W2K (as I read on this forum). I have also run defraggler on my laptop, an XP machine with the latest version and seen similar results- the need to run the program multiple times. If i watch the "current state" stats, it seems that only a few files at a time are being defragged. Am I doing something wrong?
