Diskeeper vs. PerfectDisk
Diskeeper and PerfectDisk are main leading Windows defragmenting tools in the market. The hard disk in my Windows XP machine is heavily fragmented and the MS built-in defragmenter doesn’t help very much so I decide to take a look into the commercial defragmenter tools out there. First I tried Diskeeper because I found that the Windows built-in defragmentation tool contains code licensed from Executive Software (the makers of Diskeeper). I thought that being licensed by Microsoft was a good sign but… Diskeeper like the built-in tool is a multi-pass defragmenter. That means that if you run it one time (or two or three for that matter) the hard drive will not end fully defragmented. You need to execute it periodically over a long term to end up with a fully defragmented drive. And it doesn’t consolidates free space. Diskeeper says that those two things are not important because drive performance is not affected. Doing it that way they consume less resources which is good but I found very frustrating to execute a defragmenter and end up with a slightly less fragmented disk I want a full defragmentation now!. ...
