Boost your system performance with disk defragmenter

Lets see what is Disk Derangement.

I found some useful definition from different website which can be helpful to understand Disk Derangement.

Disk Defragmenter is a utility in Microsoft Windows designed to increase access speed by rearranging files stored on a disk to occupy contiguous storage locations, a technique called defragmentation. Defragmenting a disk minimizes head travel, which reduces the time it takes to read files from and write files to the disk.Beginning with Windows XP, Disk Defragmenter also reduces system startup times.

Defragmentation is like cleaning house for your PC, it picks up all of the pieces of data that are spread across your hard drive and puts them back together again. Why is defragmentation important Because every computer suffers from the constant growth of fragmentation and if you don’t clean house, your PC suffers.
Disk fragmentation occurs when a file is broken up into pieces to fit on the disk. Because files are constantly being written, deleted and resized, fragmentation is a natural occurrence. When a file is spread out over several locations, it takes longer to read and write. But the effects of fragmentation are far more widespread: Slow PC performance, long boot-times, random crashes and freeze-ups – even a complete inability to boot up at all. Many users blame these problems on the operating system or simply think their computer is “old”, when hard disk fragmentation is most often the real culprit.

Most hard drives have spinning platters, with data stored in different places around that platter. When your computer writes data to your drive, it does so in "blocks" that are ordered sequentially from one side of the drive's platter to the other. Fragmentation happens when those files get split between blocks that are far away from each other. The hard drive then takes longer to read that file because the read head has to "visit" multiple spots on the platter. Defragmentation puts those blocks back in sequential order, so your drive head doesn't have to run around the entire platter to read a single file.
If you have a solid-state drive (SSD) in your computer, you do not need to defragment it. Solid-state drives, unlike regular hard drives, don't use a spinning platter to store data, and it doesn't take any extra time to read from different parts of the drive.

I think you understand what is Disk Derangement. But if you still don't then see the video of Technical Guruji.




To defragment your hard disk

Open Disk Defragmenter by clicking the Start button. In the search box, type Disk Defragmenter, and then, in the list of results, click Disk Defragmenter.




Under Current status, select the disk you want to defragment.
To determine if the disk needs to be defragmented or not, click Analyze disk. Administrator permission required If you're prompted for an administrator password or confirmation, type the password or provide confirmation.

Once Windows is finished analyzing the disk, you can check the percentage of fragmentation on the disk in the Last Run column. If the number is above 10%, you should defragment the disk.
Click Defragment disk. Administrator permission required If you're prompted for an administrator password or confirmation, type the password or provide confirmation.

You can also schedule it by clicking Turn on Schedule.

Note : File system FAT, or FAT32, it can't be defragmented.
