How do you determine if a hard drive should be defragmented?

The above is too complicated, according to my experience, if your hard drive is NTFS partition and not a system disk and ** disk, you don't need to defragment it for a year. If it is FAT32 and it is a system disk and a ** disk, it is recommended that it usually be half a year. In other cases, disk defragmentation is still carried out as little as possible, after all, the disk will be read continuously, and the life of the disk will also be affected.

Use Diskeeper Pro, it's better than the system and the speed is okay.

If I turn on my computer and get a flashlight, it's time to tidy up! Or use the collation program to analyze, it counts! However, it is generally not used frequently, but defragmenting does not hurt the hard drive! At least Microsoft didn't warn everyone! So don't listen to the rumors of the Internet!

Because defragmentation is a huge project.

Let's start with how the fragments are created.

In a disk partition, files are scattered and saved to different parts of the disk, rather than in a continuous cluster of disks. In addition, during file operations, the system may invoke virtual memory to synchronize the hypervisor, which will cause each program to frequently read and write to the hard disk, resulting in disk fragmentation.

You want to merge the fragmented files together and remove the fragments from the hard drive.

The files in the partition come and go until the individual files are merged into a single file, this frequent read and write operation is very hurtful to the hard disk, similar to BT (when the cache is relatively small).

However, a hard drive that is not organized will hurt the hard drive even more.

Imagine that you are running a program, which is divided into n blocks due to fragmentation, and you can't see it, so the hard disk will read this file from different starting positions, which is equivalent to the head moving N times, and it is moving frequently.

It's not cost-effective, right, so my advice is not to defragment your hard drive too often.

Each partition depends on how often you use it, basically if you finish analyzing it, you will sort it out when you say it's time to tidy up.

I don't need to tidy up for a week, basically I tidy up once a month or two months.

Not tidying up is definitely worse for the hard drive

The speed at which the disk accesses the file. This is because the disk spends the least amount of time on overhead such as seeking when reading a file.

Defragmentation is all about physically storing files together.

Because in the running of the program, disk files are inevitably used, and after a long period of use, a file may be stored in many locations on the disk, so that to read a file, the disk has to search for many times and perform some mechanical actions, which takes a lot of time. Because the operation of the disk is too frequent in the system.

Frequent defragmentation is of course detrimental to the life of the hard drive, as it involves a large number of disk reads and writes.

However, on the whole, defragmenting between the source chain at a fixed time (once a month or two months) will not only improve the disk access speed, but also protect the disk and prolong the disk service time.

This is because in the process of running the program, it is common to use disks to dump temporary or final data. This is not good for defragmentation. In particular, the partition disk where the Yusun system is located, the program has a very high usage rate.

If you are tidying up the system disk, try to get away from the computer and let it finish before operating the computer. Otherwise, you will find that the defragmentation job will not be completed for a long time.

If the decluttered disk is not a system disk, try not to run programs that might use the disk.

Therefore, it is best not to operate a computer when doing disk defragmentation. - In this way, the finishing work can be carried out the fastest and the finishing effect can also be guaranteed.

Don't keep asking questions about whether your computer is bad or not. As long as the disk is read and written, the disk can be damaged - this is an inevitable thing, and the disk is made to meet the requirements of people. -- Disks are aged in the process of tens of millions or even hundreds of millions of reads and writes, and finally they are scrapped.

In a word. Fixed, periodic defragmentation of the disk will optimize the organization of files on the disk, which will greatly improve the efficiency of disk access and protect the disk in general.

At the same time, it is advisable to suspend the use of the computer while the disk is being fragmented. In this way, we can better ensure that the defragmentation work is completed as quickly as possible and as best as possible...

Disk defragmentation should be carried out partition by partition, generally C first, followed by D, E, etc.; Each partition is carried out in two steps.

1. Check for disk file errors.

1. In the My Computer window, right-click on a disk drive letter, such as C, and select the "Properties" option in the cascading menu.

2. Switch to the "Tools" tab, click "Start Check" in "Check Errors", check "Automatically repair file errors", ask: "Check hard disk errors the next time you start the computer", click "Plan Disk Check", exit, manually restart the computer, the computer will display the disk check progress after the computer is started, finished, automatically restart the computer, and enter the desktop. Note that C is the system partition, and the partition outside C does not need to restart the computer, and the error will be checked directly.

2. Defragmentation.

1. In the My Computer window, right-click on a disk drive letter, such as C, and select the "Properties" option in the cascading menu.

2. Click the "Defragment Now" button in "Magnetic Sheet Sorter" to open the "Defragmenter" window.

3. Select the disk partition you want to shredd, such as C, click the "Analyze Disk" button, after the analysis is completed, check the disk fragmentation percentage, generally less than 10%, you can exit without sorting. If you need to defragment, click the "Disk Defragmentation" button to display the progress and complete the defragmentation.

3. Pay attention when tidying up.

1. Do not read and write any data during the sorting period, and close all running programs, especially virus real-time monitoring programs and screen savers, because one party is sorting it out, and the other party is using it to produce conflicts, which will affect the sorting speed, and sometimes it is likely to cause the computer to crash and cannot be sorted out.

2. Disk defragmentation is a process of reading and writing a large information capacity of the hard disk, and the wear and tear of the disk disk is much greater than that of ordinary use, so only when the disk fragmentation needs to be sorted out to a certain extent, the disk can be fragmented. Whether it should be sorted or not, through the analysis of the disk before tidying, it will prompt you whether the partition should be sorted out or not. So you have to tidy up when it's time to tidy up, but it doesn't have to be on a regular basis.
