Don't have any experience with TTP file defrag/optimize feature, but if I'm not mistaken, only Norton Speed Disk has a profile for OSX. Even though TTP runs on OSX, I think it uses the same optimization profile for OSX as it does for OS9. And that definately isn't appropriate for OSX. The same goes for Disk Warrior.
