What harm disk fragmentation can cause to the system

The efficiency and speed of system operation are reduced. In the long run, it will also reduce the lifespan of the hard drive.

Before disk defragmentation, you can set System Disk Doctor to run automatically first

Note. Because the hard disk is spinning at high speed during disk defragmentation, frequent data reading and writing at this time may cause the computer to crash, and even lead to hard disk damage in serious cases. Be sure to turn off other programs including screen savers, virus firewalls, chat software, and **** during the sorting process.

The number of processes cannot exceed 21

Windows Optimizer recommends that users conduct regular analysis once a month.

I recommend that users who play games every day analyze it once every three months. Users who play games on Sundays are analyzed once every five months. Arrange a plate for 1 hour.

Finishing once may add life. Open the software on your computer. will make the finishing fail to finish. Reduce the life of a few months to the point where the hard drive is damaged.

In my opinion, when collating, the process should not exceed no more than 10%.

My personal simple understanding is that disk fragmentation is unusable space on the hard disk, and junk files are useless files on the hard disk.

The specific reasons for them are as follows:

Disk fragmentation: In disk partitions, files are scattered and saved to different parts of the disk, rather than in successive clusters of disks. In addition, during file operations, the Windows system may call virtual memory to synchronize the hypervisor, which will cause each program to frequently read and write to the hard disk, resulting in disk fragmentation.

Junk files:1. When installing many software, the first thing to do is to extract the installation files to a temporary directory and then install them in this directory.

Generally speaking, these temporary files are automatically deleted when the installation is complete. But sometimes due to a crash, a sudden power outage, or the software itself is not well designed, these files are not deleted, and they are left on your hard drive as "garbage".

2。There are also various junk files that are produced when the software is running, and there are many types. For example, the WinZip temporary file has some programs that generate *old、*.bak file, the system's help files will also generate some.

temporary garbage", their extension is often *gid、*.fts、*.ftg, some software will also produce some at runtime. Temporary files with tmp as the suffix.

Khan: It's a long one upstairs.

Basically, there is no harm Some people have never used a defragmentation computer at all, and they have used it for 3 or 4 years.

The few people upstairs have said enough.

In fact, too much fragmentation increases the read time of the hard disk.

It's like you put everything together and find it all at once when you need it.

If it's messy, then you have to go there and look for it, and go here and look for it, and it has a certain impact on the hard drive.

But keep in mind that defragmentation too often hurts your hard drive more than you never declutter...

It will take up disk space and affect the read speed, so it is still good to clear it regularly.

It's not harmful, it's just a little bit of an impact on the speed of the computer.

I think this Super Bunny is pretty easy to use.

1. When the physical memory required by the application is insufficient, the general operating system will generate a temporary swap file in the hard disk, and use the hard disk space occupied by the file to virtualize the memory. The virtual memory manager will read and write to the hard disk frequently, resulting in a large amount of fragmentation.

2. When the content of a cluster (composed of sectors) in the middle is deleted, a smaller file is newly written, so that there will be some space on both sides of the file, and then a file is written, and any part of the two spaces cannot accommodate the file, so the file needs to be divided into two parts, and the disk fragmentation is generated again.

3. ** is an important source of debris. For example, the ** file will be forced to be divided into several fragments and stored on the hard disk. In addition, if the file space is not large enough, a large number of disk fragments will be generated, and this situation will become more and more serious with the frequent deletion and modification of files.

Disk fragmentation does not have a significant impact on normal operation, but it can significantly slow down the operation of the hard disk, mainly because the hard disk needs to jump between multiple fragments to read files, which increases the latency of waiting for the platter to rotate to the specified sector and the seek time required for the head to switch tracks. After a long time of computer use, a large number of files are stored on the disk, these files are not saved in a continuous disk space, but a file is scattered in many places, these scattered files are called "disk fragments", these fragments will reduce the performance of the entire Windows, every time the disk contacts of reading and writing files have to move back and forth, wasting time.

The computer disk is fragmented, which will occupy a lot of disk space, especially when many programs are opened, some programs will produce some temporary files, which occupy a lot of disk space, so it is easy to cause crashes.

It will not have any effect, disk fragmentation is to speed up the reading ability of the disk, when a file is scattered in many places on the disk, the computer will repeatedly find it when reading and writing, although the current seek method is optimized and improved, but too many fragments will increase the number of seeks, and the defragmentation type took a long time, it seems to have some impact on the disk, which can be much larger than the load accumulated by the fragmentation of the computer that we usually use. Of course, you can't do debris cleaning endlessly, once every 2 months.

Treat the C disk and D disk as a drawer, and the files we store on the computer are equivalent to us putting items in the drawer, but they are placed irregularly and scattered, and each item can be called a "fragment".

Dizzy, pure nonsense, how can it be the garbage generated by the Internet.

To put it simply, when your hard disk is repeatedly read and written, and when it is stored, the data will be stored in various areas, and when you delete the data and write it repeatedly, there will be a discontinuity of disk space, which is the so-called fragmentation.

This thing can be sorted out once every 3 months or so, and if it is not sorted out for 1 year and a half, there will be a lot. Resulting in poor disk performance.

Cleaning up the debris takes a lot of time, and you need to be careful when cleaning the C drive.

It is because Microsoft's software algorithm does not do a good job that when storing files and deleting files, there are more scattered free units between the occupied disk space units, which are distributed all over the disk and cannot be used as a whole like fragments, which is called disk fragmentation. Defragmentation tools are required to rearrange and allocate storage space to reduce disk fragmentation.

A better operating system, such as UNIX, does not produce a lot of disk fragmentation because it is constantly cleaning up free units while using and deleting files.

Part 1: What is Disk Defragmentation?

Although it is not a big deal, it is not very good, the hard disk has its life, and frequent reading and writing will consume its life (not much).

It is recommended to defragment once a month, and do not overdo it.

The computer boots up a little faster, but there will be some damage to the hard disk.

Not the cause of the fragments. Fragmentation is mostly just slow when accessing programs and opening files. The crash is something else.

That is, some of the files in the computer are not stored continuously, and the files are divided into several parts and distributed in different storage locations.

Defragmentation is to try to organize and move a file together, so that the reading will speed up.

As for the impact, because it is to get the entire hard disk over, so for the hard disk, it is a "hard work", of course, it will have a little impact on the hard disk, don't tidy it up frequently.
