The computer suddenly slows down, and when you turn it on, you have to check the hard disk to say th

bad cluster

After the user has partitioned the hard disk and advanced formatted it, a File Allocation Table (FAT) is created for each partition. The FAT records the usage and interconnection of all clusters in the area. If a cluster is found to have bad sectors in the process of advanced formatting (or scanning by the utility software), the cluster is recorded as a bad cluster in the FAT and the cluster is no longer used when storing files in the future to avoid data loss.

Sometimes, viruses or malware may also mark a normal cluster with no bad sectors as a bad cluster in the FAT, resulting in the normal cluster not being used. It is important to emphasize here that each cluster consists of several sectors, and as long as there is a bad sector in it, the rest of the sectors in the entire cluster are no longer used.

It is recommended to use a partition magician to fine-tune the partition and try it! If the hard disk still reports an error after minor adjustments, it is recommended to reinstall the system under the Advanced Format under DOS.

After booting, right-click the system inventory tool, detect and repair are checked, and then restart, if there are still bad sectors, you have to find a tool to isolate the bad sectors. If there is a lot of isolation, it is better to do it all over the system!

Hard drive is toxic·· It is highly recommended to format them all.

Then check the hard drive to see if there are any bad sectors.

Is it a sign that the computer is turning on very slowly?

Answers. 1.It doesn't have to be that the hard drive is bad, there are other factors as well.

2.Reason: The computer's system cache has too much junk, which affects the boot speed, which can be solved by cleaning the junk cache.

3.The system level of the computer is outdated, which can be solved by updating the system.

4.The hard disk is aging and running slower, which can be solved by replacing the hard drive.

1. It is not clear what the aging process of semiconductor CPU and memory is, but the CPU may have a robust design, and the failure of some computing units can be replaced by other units, but the overall computing power is lost. The same goes for memory.

2. No matter how much the change of the basic resistor-capacitance components on the circuit board should be, it will not affect the speed. Unless there are some special signals, such as the signal bus of the IIC, the IC that needs to send data will pull the bus level up or down before proceeding to the next step (but the high-speed bus should not use this, and the high-speed bus structure is not very clear.)

3. Hard disk bad sectors are divided into two types: logical bad sectors and physical bad sectors. The former is a soft bad sector, which is usually caused by improper operation or use of software, and can be repaired by software; The latter is a physical bad sector, which indicates that there is physical damage on the tracks of your hard drive, and it can only be solved by changing the usage of the hard drive partition or sector.

4. When opening, running or copying a file, the operation speed of the hard disk slows down, and it may be unsuccessful for a long time or it is manifested as a long time of "gnawing" a certain area, or at the same time there is an abnormal sound of the hard disk reading, or simply the Windows system prompts "unable to read or write the file". These can indicate that there is a bad sector in a part of your hard drive.

5. Every time you turn it on, the ScanDisk scanner will run automatically. This is definitely an indication that there are important errors on the hard drive that need to be fixed, such as bad sectors. If you can't pass the program when you run it, it means that the hard disk must have bad sectors, or although the scan can also pass, a red "B" mark appears, indicating that the hard disk also has bad sectors.

It doesn't have to be a broken hard drive, it could be a system problem, too much junk, or poisoning, you can:

Check the application software or drivers.

Some programs slow down the computer system when it starts. If we want to be the reason for this, we can start from "Safe Mode". Because this is the original boot, Safe Mode runs slower than it did normally.

However, if you start up in Safe Mode and find that your computer starts up faster than you normally would, there may be a program that's causing your system to boot up slower.

2.Too many desktop icons can get you into trouble.

Having too many icons on your desktop can also slow down your system boot up. Every time Windows starts up and displays the desktop, you need to find the icons of the desktop shortcuts one by one and load them, the more icons you have, the more time it takes, of course. Multi-delete point icon.

3.Remove the random starter.

You can use Kingsoft Poison's boot optimization function to increase the boot speed with one click.

4.If your computer is infected with a virus, the system will run significantly slower. It is recommended to use Kingsoft Antivirus's quick detection and killing function to detect and kill computer viruses with one click and improve the running speed of your computer!

5.You can use 360 to clean up garbage with one click, if these don't work, you can change the system, and if you change the system, it may be a hard disk problem.

Not necessarily.

If there are many software that are started together when the device is turned on, it will take time.

There is also the old computer configuration is relatively low, even if the new system is made, it is very slow to boot.

There is also the problem with the hard disk you mentioned, and there will also be a slow boot.

Specifically, you still have to find a professional to help you test.

You're obviously a hard drive that's broken, there's a sound, hurry up and buy a hard drive and copy the useful stuff, or it's impossible to copy it in a few days.

It's possible that there is a problem with the hard drive.

The latency is too high. Use a disc to enter the DOS toolbox. Then enter:

MHDD (Hard Disk Detection) and then enter scan on the MHDD interface: Scan and then press Enter and press F4 for hard disk bad sector detection. It is estimated that the hard disk will be sacrificed honorably!

Definitely a lot of high latency.

It should be that there is a problem with your hard disk.,If you change the hard disk, just bring the ghost backup file over.,Otherwise, it's useless to copy the system disk files directly.。 They'll do it. Your motherboard can support any serial port.

The physical damage of the hard disk is not only in the bad sector There are other reasons Send it to a professional store to test The hard disk has a different abnormal sound than before And the sound is loud It is estimated that it should retire Congratulations You should have a new hard disk again.

It's been like this for a long time, it's normal, generally as long as you don't do anything special, such as a sudden power failure that can't hurt the hard disk.

You first use this software to detect your hard drive hdtune, if you change it, you can change the 500g hard drive!

Not necessarily, sometimes it's a system problem.
