Being rather new to Vista this week, I was sorely disappointed to see the severely dumbed down defrag utility in Vista. A pathetic effort. Really! So after a few highly scientific Google searches, I settled on O&O Defrag and could not be happier.
Here's the lame, incredibly useless UI in Vista's Disk Defragmenter. Note, if you are going to use some other defragmenter on a schedule, which I would recommend, be sure to disable the regularly scheduled Vista defragmenter by unchecking the box. One way of getting there is to go to the Control Panel and then Performance Information and Tools and then Advanced Tools.
And here is only part of the incredibly useful O&O Defrag UI, a shot taken as it defrags my drives:
Of course there are other suitable defrag tools such as DiskKeeper and others. Perhaps Microsoft wanted the Vista tool to cater only to the basic, uninformed user. If so, they certainly left the market wide open to the more sophisticated tools vendors such as O&O.
