Disk defragmentation results in better performance of your hard disk, some people don’t realize that. Windows come with a build-in defragmentation tool, but is too slow sometimes. If your computer activity involves a lot of hard disk usage, it is recommended that you should defrag and optimize your hard disk at least once a month.
One of my favorite 3rd party defragger is MyDefrag(formerly named JKDefrag) that allows you to quickly defrag and optimize your local drives. It can also perform the operation on external hard disk, USB Drive, or Flash Drive. It does not come as one tool, rather it has a few separate programs, each for one task as shown in the screenshot below.
Once you run an Analyze or Defrag operation, it will perform it on the whole hard disk, one drive at a time. You can continue the operation to the next drive by clicking Run > Continue. You can zoom to any level inside the Diskmap and also view the overall statistics.
So why use MyDefrag instead of the default Windows build-in Defrag utility? Because according to the developer, it is much faster, has more broader options, is customizable, and much more. Overall, the Fast Optimize operation is what I like the most.
It is compatible with Windows 2003, Windows XP, Windows Server 2003/2008, Windows Vista, and Windows 7. Both 32-bit and 64-bit OS are supported. For more, also check out Defraggler and Windows 7 Disk Defragmentation. Enjoy!
