The fragmentation of data on a hard drive occurs naturally over time. Installing
new software or hardware is one way this can happen. Editing photos, movies or music,
which tend to be large in size, can also cause fragmentation. Any time I
install a service pack, I always defragment the drive, before and after the installation.
It is always a good idea to delete any unnecessary files before defragmenting.
I run Disk Cleanup and CCleaner to quickly remove hidden temp and log files.
The first time I defragment a drive, I remove the pagefile first. The pagefile is unmovable and
can get placed between blocks of data. If the pagefile dynamically sizes itself,
that will cause fragmentation. The video shows how I turn the pagefile off and back on.
I, also, show how I use the defrag command and setup a scheduled task.
To defragment a drive: Start Button >>> My Computer >>>
(right-click the desired drive) Properties. Tools Tab >>> Defragment Now Button >>> Select Drive >>> Defragment Button.
