A better way to defrag your hard disk
In the long list of odious chores, defragmenting your hard drive is right up there with flossing your teeth and washing your dog--or flossing your dog's teeth, for that matter.
There is little agreement on how much--or even whether--defragmenting improves your PC's performance, but having files closer together on the disk reduces the amount of movement required by the drive's mechanical parts. This should make it last longer, though such factors as operating environment and the quality of its components probably have a greater impact on its life span.
Regardless of whether it will actually improve your system's performance and reliability, I do know that there's a better way to defragment your drive than using the utility built into Windows: you'll get the job done in less time by using Auslogics' free Disk Defrag utility.
