Why you should defrag your hard drive

As you use your computer over time files are saved, re-saved, deleted and modified random pieces of that data get scattered across the different sectors of your hard drive. This scattered data then has to be located by the hard drive every time and results in extra rotations than necessary.

All these extra rotations result in a slower experience as the hard drive needs to work harder to locate the individual pieces of data as your computer tries to access them. The process of defragging your hard drive consolidates all the files into a single block making it easier for your hard drive to locate and piece together.

Therefore if you are still using a traditional hard drive then you should defrag your hard drive regularly to ensure it is running at optimal speeds whenever you use your computer. Prior to defragging your hard drive you want to ensure any open files/documents are closed and any open programs have been closed.

By closing any running programs this will help to avoid any potential errors which can result in some fragmented data not been properly defragmented.
