I am sure that you hope your computer can always work very well without any problem. To be honest, it is not so easy to do that. But you can do some maintenance for your computer.
If you want to protect your computer, defragmentation is really a useful way to do that. But if you still fear that it can harm your computer, you can find the answer in this article.

In order to explain it specifically, let us see how the disk fragments are produced.
The files in the disk are kept in order based on the restored time. Theoretically, such files should be put closely without any space between them. However, it is unavoidable for you to change files such as deleting or moving them. Well, the new added or removed content is not put into the original position but the end of disk restoring space. And the system will make mark between the original and added files.

As time goes by, when many files are changed, there are a bunch of discontinuous files in the disk. Or if you delete any of them, its space becomes empty and can not be filled automatically. And, the new ones cannot put here any more and on the contrary, such space cannot restore new files, too. In this way, the empty space is wasted and can results in disk fragments.

Just as I mentioned above since the plus content and previous one are separated, if you want to view them, the disk head has to read and write them back and forth. This is one of the main causes of slow computer speed. System has to pay more time to fetch such files. If you still turn a blind eye to such problem, the computer will be lagged by such increasingly piling up disk fragments.

You can defragment disk by using the Windows program or the other tools like “Advanced Defrag” . But if there is a GHOST system backup file in the partition, you should not defragment this disk because it can lead to the system go awry when restoring. That is to say, before defragmentation, you should check the disks first.

And if it can neither analyze nor defragment disk in the normal condition, you can do that under “Safe Mode”. You can press “F8” when starting up computer. Because in the “Safe Mode” the system does not have to load much more programs than in the normal condition. At last, if it can not defragment disk, you should check whether there is any broken track in the disk. if so, it can hinder the process of defragmentation.

You see, if you have not done that, it is urgent for you to defragment disk now. To say the least, defragmentation can not do any harm to your computer, it is worthwhile having a try.
