Good maintenance of hard disk plays a significant role in performance of a computer. Disk Defragmenter is a software program used to reorganize file storage on the hard disk drive so that the files are not scattered.
Generally when we save a file in our computer, the bytes of the file are stored in various empty places in the hard drive.
Later, when we remove that file, all the bytes of that file are deleted by leaving the space used by those bytes useless.
Running Defragmenter fills the empty space left by the deleted bytes by pushing together all the data so that we can get large empty space on the hard drive for the tasks that require more memory.

So, defragmenter unites each scattered program in the hard disk drive so that the data can be quickly accessed. Running Defragmenter regularly makes the computer to run faster with more efficiency because it reorganizes the files.
We should close all the programs and files before starting the Defragmenter. Running Defragmenter may take several hours if we are doing it after so many days.
While running Defragmenter, if we work anything on computer without keeping the Defragmenter at pause, then the Defragmenter starts again from the beginning because of the change in contents of the computer.
So, we should use the pause button if we want to do any work while Defragmenter is running.
In our computer, we can check defrag at:
In Windows XP, Start -> Programs -> Accessories -> System Tools -> Disk Defragmenter. (Or)
My Computer -> Right click on the drive we want (C or D) ->Properties ->Tools ->Defragment Now…
Running defrag is recommended after:
(a)Deleting many files.
(b)Adding large number of files.
(c)Installing new programs.
(d)If the total free hard disk space is less than 15%.
It is recommended to run defrag at least once in a month to have the better performance of hard disk. We can only increase the performance of the hard drives by running defrag but not on other drives like flash drive or jump drive.
Even if we run defrag on other drives, there will be no increase in the performance. Further if may reduce the life span of the drive because every time the data is written using defrag, the drive is degraded.
