Title: Works great!
Review: This disk utility actually works on OS X. I ran it on 10.2.3. After extensive video editing, I wanted to defrag--Norton Utilities wouldn't do it because it kept telling me my disk had errors. I ran Drive 10, checked my disks for errors (there were none) and defragged with no problem. My system is noticeably faster now. Drive 10 is very easy to use. Be sure to check for updates online--the defragger is part of an update. A menu option makes this very easy.
