What Is Defragmentation? Over time, the data blocks (fragments) that make up files can become scattered in multiple locations around the surface of the hard disk. This is called fragmentation. Defragmenting moves all of those blocks so they are located close together in physical space, which potentially speeds up read times when accessing data on the disk. However, with modern computers, Still, it doesn’t hurt to keep your drives operating in the most efficient way possible. You might also need to defragment external hard disk drives connected via USB, as they may not be plugged in when Windows runs its automatic defragmentation.

Fragmentation makes your hard disk do extra work that can slow down your computer. Removable storage devices such as USB flash drives can also become fragmented. Disk Defragmenter in Windows rearranges fragmented data so your disks and drives can work more efficiently. Disk Defragmenter runs on a schedule, but you can also analyze and defragment your disks and drives manually. To do this, follow these steps: 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. 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. If you're prompted for an administrator password or confirmation, type the password or provide confirmation. Disk Defragmenter might take from several minutes to a few hours to finish, depending on the size and degree of fragmentation of your hard disk. You can still use your computer during the defragmentation process. Notes: • If the disk is already in exclusive use by another program or is formatted using a file system other t...

Over the years, improvements have been made to the Windows drive optimization tool. However, even when the operating system can accurately detect the type of storage and handle defragmentation of files automatically, it's not always optimal. Because you may not keep your PC turned on long enough or you may have an external hard drive that it's not always connected to your computer that prevents maintenance from running properly. As a result, the time will come when you'll begin to notice that opening apps and saving files to disk will take longer than usual, in which case manual optimization may be required. In this Windows 10 guide, we'll show you the easy steps to check if your hard drive is fragmented and defragment as necessary to keep your computer running more efficiently. How to use Optimize Drives on Windows 10 • Open Start type Defragment and Optimize Drives and press Enter. • Select the hard drive you want to optimize and click Analyze. Note: You always want to analyze the drive first to figure out if the drive needs optimization. If the result shows less than 10% fragmented, you probably don't need to optimize the drive. • If the files stored on your PC's hard drive are scattered everyone and defragmentation is needed, then click the Optimize button. • Once the process complete, the current status should display "0% fragmented". Note: Keep in mind that depending on the number of files, the size of the drive, and fragmentation, the defragmentation tool may take s...

Disk Fragmentation: Should You Do It and How to Run Windows Defragmenter If your PC is running slower than it should, it could be the usual suspects, like background programs or viruses. Or it could be file fragmentation, which means that your files are scattered all over your hard disk in a chaotic manner. This is such a major (and common) performance hit, Windows comes with its own disk defragmenter. How do I check if I’ve got an SSD or an HDD? A great majority of the world’s PC users still rely on mechanical disks. Despite the push by manufacturers to replace the old clunky HDDs with SSDs, around two-thirds of new PCs sold this year will still use the older technology. So unless you’ve got a state-of-the-art machine, you probably have one of these older devices. To verify this, fire up the built-in defrag tool: open the Windows Start menu, type in Defrag and hit the Enter key.

If your PC is running low on free space, you might not be able to install important Windows updates, and your PC’s performance may be affected. Here are some ways to free up space so you can keep your PC up to date and running smoothly. These suggestions are listed in order, so start with the first one, see if that helps, and then continue to the next one if it doesn't. To check the total disk space left on your Windows 11 device, select File Explorer from the taskbar, and then select This PC on the left. The available space on your drive will appear under Devices and drives. If you don't want to use Storage Sense, Cleanup recommendations can help you identify and clean up temporary files and system files from your device. • Select Start > Settings > System > Storage > Cleanup recommendations. • Review each of the categories, including Temporary files, Large or unused files, Files synced to the cloud, and Unused apps, and select the items you'd like to remove. Windows will suggest files for you and show the amount of space you'll save when you remove those items. • After you've selected items to remove, select the Clean up button for each section. Note: If it’s been fewer than 10 days since you upgraded to Windows 10, your previous version of Windows will be listed as a system file you can delete. If you need to free up drive space, you can delete it, but keep in mind that you'll be deleting your Windows.old folder, which contains files that give you the option to go back ...

Disk Defragmenter might take from several minutes to a few hours to finish, depending on the size and degree of fragmentation of your hard disk. You can still use your computer during the defragmentation process. Microsoft never specifically says, because Windows auto-detects the needed settings. The amount and time is different for every situation. "few hours" my foot ... here I'm at step 4 and time spent so far "only" 30 hours, but I needed it, surface test of the hdd and overall speed test GOOD but transfer speed both write and read was becoming really poor (3-5M/s down from the initially over 100M/s) so, defrag was the only idea I was thinking it may be the problem and first analyse was 75% fragmented (which I google and seems to be ... CRITICAL) and disk is (a laptop - 2.5") 1T with 50G free so I guess it may be right but still ... "few hours" my foot :P Windows 8 and up auto-detects the number of passes required depending on the SMART status, number of errors, size of disk, time since last inspection, etc. You can keep it running in background and does not affect your performance much on a decently speced device. It can take anywhere from 1-2 passes to 40 passes and more to complete. There is no set amount of defrag. You can also manually set the passes required if you use third party tools. Ho much fragmented was your drive?

The main hardware components of your computer – the processor, memory, and internal storage – work in tandem to enable you to access files and load programs. While the RAM and processor do their work at lightning speed, the internal storage, especially if it is an HDD, sadly lags behind. Due to its physical limitations, a typical hard disk drive is very slow and cannot keep up with the processor speed. Solid-state drives, while much faster than mechanical drives, still work at crawling speed in comparison with the latest chips. As a result, reading and writing data can be excruciatingly slow processes, especially when the process of natural file fragmentation steps in and worsens the situation. This is why defragmenting your hard drive is necessary, even in 2023. It reverses file fragmentation and helps to improve computer performance. If you have previously come across the topic and found it couched in arcane language and opaque computer-speak, you will find this article both refreshing and illuminating. The truth is that disk defragmentation is not so much a complex subject as a poorly explained one. To fully comprehend what defragmenting a hard disk entails, some concepts like fragmentation and the Windows file system need to be understood. Knowing how the traditional hard disk works and how SSDs are different will also help you to know why the former should be defragmented for optimum performance while the latter will do just fine without it. First, let’s explain how t...

Hard drive defragmentation is more like routine maintenance of any machine, such as a car, which has to be done periodically. In this context, it can be quickly put off since it can be inconvenient and unexciting. With machines, most people understand the need for periodic maintenance like oil changes. However, the same is not clear to many as to what disk defragmentation entails. All the info you get from Windows is that Disk Defragmentation and Drive Optimization will make your hard disk perform better. This begs the question, what is disk fragmentation and how does it happen? Read More: Causes Of Disk Fragmentation Disk fragmentation is a consequence of how a mechanical hard disk writes and arranges data. Consider an empty hard disk to be a new blank exercise book. When you first copy files to it, they are all arranged to start from the first page towards the last. However, as time moves, you may need to delete a file or move it from one folder to another. Now, if you delete a file that was stored close to page 1 you will have some free empty space in the middle of other existing data. Now imagine repeating those delete operations over and over. You end up with gaps of unwritten spaces scattered all over the drive. A fragmented DIsk Now let’s assume at this point you bring in a relatively huge file to this hard drive. What will happen is that the computer will first place part of the huge file in the free available gaps until they are all filled up. Then whatever remain...
