I have the newest version and have had the program on my drive for ages. It\'s lame! It\'s worth about $15 at most. It doesn\'t do anything you can\'t do from the shell yourself.
The manual is probably why this applet is popular at all. It\'s a wordy pile of hype and techno-jargon that really makes this seem awesome. Too bad they didn\'t spend the time to make better and more features tho. Of all the drive repair and recovery tools this is the red-headed step-child with empty pockets and holes in his knees.
Drobo or some company might mention this tool as good because it has the smallest footprint (less features = smaller app) and has a GUI for the three most common things (which are the ONLY things DW does BTW) one does for common drive maintenance: structure repair, file scanning, and scheduled S.M.A.R.T. monitoring. Oh you can do Repair Permissions with it too. :P It\'s not faster or better than diskutil or fsck/fsck_hfs and a free SMART monitor like smartctrl - and in fact is slower at a few things.
To me it might be worth $10 or $15 to put those things in one convenient little GUI (if I didn\'t already know how to do that myself). If you want a suite of tools that actually does something beyond which comes free with OS X already then maybe:
