How To Defragment Hard Drive Of Your Computer – In terms of computer storage, fragmentation describes a phenomenon that occurs when space is used inefficiently, reducing capacity and/or performance. In many cases, this leads to storage space being wasted. But this depends on the file system.
There are three different types of fragmentation: external fragmentation, internal fragmentation, and data fragmentation. These occur in isolation or in conjunction with each other.
To combat this Window’s introduce the Disk Defragmenter. The Windows Disk Defragmenter has been a part of Windows since Window 95. While the latest versions of Windows run the disk defragmenter automatically, you might still want to run it manually from time to time.
Defragmenting hard drive regularly ensures that your PC runs at its best. It also contributes to the health and lifespan of your hard drive.
Fragmentation can be lethal. In some very severe cases, it could cause a process or system to fail due to premature resource exhaustion.
Fragmentation also causes some performance degradation. It actually increases the amount of work your hard drive has to do to allocate and access a resource.
As mentioned above, there are three types of Fragmentation:
Sometimes, due to memory allocation rules, your hard-drive could allocate more memory or space than is needed.
For example, memory can only be provided to programs in chunks divisible by 4, 8 or 16, and as a result, if a program requests perhaps 29 bytes, it will actually get a chunk of 32 bytes. In this example, 3 bytes have gone to waste.
External fragmentation arises when free memory is separated into small blocks and is interspersed by allocated memory. It is a weakness of certain storage allocation algorithms when they fail to order memory used by programs efficiently.
The result is that, although free storage is available, it is effectively unusable because it is divided into pieces that are too small individually to satisfy the demands of the application. The term “external” refers to the fact that the unusable storage is outside the allocated regions.
Data fragmentation occurs when a collection of data in memory is broken up into many pieces that are not close together. It is typically the result of attempting to insert a large object into storage that has already suffered external fragmentation.
Now that we understand the basics of fragmentation, let’s talk about how we can remedy it on your PC.
*Note: Defragment Hard Drive may take a while. If you have energy-saving features, they could cause the defragmenter to stop and start all over again. Try running your defrag overnight. You can also set up the procedure to run automatically at a preset period of time, such as once every two weeks, by using the Configure Schedule button in the Disk Defragmenter window.
A notification displays the progress of defrag hard drive. When the defragmenting process is complete, the Disk Defragmenter dialog box shows that your drive no longer requires defragmenting.

Hopefully, after reading this article, you’ll know how to defragment hard drive on nearly every Windows Operating System. It should be noted that you do not need to defragment hard drive if it’s an SSD. As a matter of fact, defragging hard drive may actually cause more harm to it than help it because it overworks the drive.
This reason is also why Apple does not offer any defragmentation tools with its Disk Utility. They figured that if you’re running any version of OS X or later, you don’t need defragging cause you’re probably using an SSD. OS X, as well as mcOS, have their own built-in safeguards that prevent files from becoming fragmented in the first place. If you don’t trust these safeguards, you can always download some third party software.
The same can be said for Linux. Because of the success of the journalized file systems used by most distributions including EXT2,3 and 4, JFS, ZFS, XFS, ReiserFS and BTRFS, you might not need to defrag because of the way the files are allocated in the disks. On some rare occasions, fragmentation may occur. If you want to defrag your drive on Linux, we recommend that you download a defrag application like e2fsprogs.
