If the hard disk fails, the problem with the hard disk does not affect the normal use for the time b

This is usually when the system detects that the hard disk has a read and write failure. There are two types of read and write failures: logical and physical, i.e., one is a software problem and the other is a hardware problem.

Logically, try to repartition the hard drive and reinstall the operating system, you may be able to repair the physical one, make a backup of important data, and the hard drive may stop working at any time. There is a problem with the hard disk, which will not affect the normal use for the time being, it is recommended to back up the system image and important data in advance, just in case. Hard disks can be used for various reasons, and there is a logical or physical damage to the track.

You can use the ghost cloning software under PE to make an image backup of the system for saving the system after a system crash. Hard disks are valuable, data is priceless, so use the computer elegantly, do not use the hard disk to read and write in a vibration environment, so as not to damage the hard disk tracks. Install the necessary firewall and anti-virus software to reduce the damage caused by viruses to system files and hard disks.

For mobile hard disks, I believe that everyone often uses them, and it is also a relatively common storage device, but many people often accidentally format or delete it by mistake when operating the hard disk, resulting in the loss of data. So for these lost data files, can they still be recovered? Hard Drive Data Recovery Method!

In fact, for files formatted on the hard disk, it is generally possible to recover, because when the computer deletes the file, it generally marks the deleted file as "free", and does not really delete it, but uses another form to store the file.

Generally, there are bad sectors on the hard disk, just like the prompt says it will not affect the use, you can use the tool on the U disk boot disk to shield the bad sectors, it should be on the partition tool, or make a U disk boot disk for use in case of problems, the system can be backed up.

Be prepared to back up your important data.

It is recommended to back up the important data on this problematic hard drive to a non-problematic hard drive, so as to avoid unnecessary losses.

In addition, hard disk repair to know that the hard disk is the first problem, you can use the Windows built-in chkdsk tool to determine whether it is a bad disk sector. If there are bad sectors or system file errors, you can try to fix them with the built-in tools of the system.

1. hd tune

It is a very popular software in China, which can evaluate how to improve the performance of hard disks from many aspects.

2. hddlife pro

It is different from general hard disk monitoring software, what it monitors is not the capacity change of the hard disk, but the health status of the hard disk.

3. fujitsu diagnostic (ide)

The hard disk bad sector detection tool can quickly verify whether the hard disk is damaged and supports data detection.

4. norton disk doctor

An excellent disk detection and repair tool that safely and easily diagnoses and repairs all kinds of disk failures, repairs logical errors, bad sectors, missing clusters on hard disks and removable storage devices, and examines every item from the disk's partition table to the physical surface.

Extended Information: Hard Drive Bad Sector Symptoms.

Once there are bad sectors on the disk, it will show some abnormal conditions, such as making strange noises, unable to complete partitioning and formatting operations, and errors when reading files or running programs. If your hard drive has any of the following phenomena, you should pay attention to whether the hard drive has developed bad sectors:

when reading a file or running a program;

The sound of the hard disk suddenly changed from a normal friction sound to a strange sound.

If the virus infection is ruled out, the system cannot boot normally, and a message such as "sector not found" or "general error in reading drive c" is displayed.

information on the hard disk, to a certain progress stopped, and finally an error is reported, unable to complete;

Every time the system is turned on, it will automatically run the scandisk scan for disk errors.

When fdisk is executed on a hard disk, it will repeatedly advance and retreat to a certain progress.

You can't boot the system through the hard disk when you boot it, you can go to the hard disk letter after booting with a floppy disk, but you can't get in, and you can't use sys command to transmit the system successfully. In this case, it is very likely that there is a problem with the boot sector of the hard drive.

If you get the above error, you need to be extra careful, which means that your hard drive has bad sectors.

Once there is a frequent problem with the operation of the system, it is necessary to check the hard disk to decide whether to repair or replace it to avoid data loss.

How to solve the problem that the computer often does not recognize the hard disk failure.

Recently, the author Bai asked such a question: what happens if the hard disk of the computer is broken? In response to this question, the author would like to talk about my personal views.

Since the hard disk is the necessary hardware for computer storage and system file storage, if it is a mild hard disk is broken, such as a serious bad sector, the computer may be very stuck, or even unable to boot, and then the hard disk is completely broken, then the computer can not enter the system at all, and it will prompt that the disk cannot be found when it is turned on, as shown in the following figure:

The hard disk is completely broken, and the boot prompts that the disk cannot be found.

If the hard disk is broken, the hard disk will not be found directly, or the hard disk has an abnormal sound, or the machine starts to the hard disk where there is a prompt, and the hard disk has bad sectors, and the hard disk enters the system or is particularly slow when the system is running. When we use the computer as an everyday tool, have you ever thought about one thing: what to do if the computer's hard drive is broken?

Many teachers have had computers that have broken down, but fortunately they have not been hard drives. So after a few days of painful waiting, some even got a little money, and everything was restored.

If fixing(D:)Stage 1 occurs, the D drive is faulty.

The failure of the hard disk is generally divided into pure hardware failure and software failure, relatively speaking, the hardware failure caused by the software is more complicated, because the hard disk involves system software and application software, but the solution is sometimes very simple, sometimes all the problems are gone after restarting or reinstalling the system!

Hardware-only failures are trickier. Hardware failures can be divided into system-caused, such as loose IDE interfaces of the motherboard, incompatibility with other hardware devices, unstable power supply, etc., and the other is the failure of the hard disk itself, such as bad sectors, partition table corruption, viruses, etc.

Symptoms of bad sectors appear:

a. When reading and writing hard disks, the screen often prompts information such as "Sector Not Found" or "General Error in Read-ing Drive C".

b. The system cannot be booted through the hard disk when booted, and the floppy disk can be turned to the hard disk letter after booting, but it cannot be entered, and the system can not be successfully booted with sys commands (such as displaying non-system disk, etc.).

c. Reading a file or running a software often makes mistakes, or it takes a long time to read successfully, during which the hard disk keeps reading the disk and makes a harsh noise. This phenomenon means that some sectors of the hard letter matching disk that contain data are broken.

d. When using the computer normally, there is often a black screen or blue screen inexplicably.

1. The performance of computer hard disk failure is as follows:

1) Intelligent fault prompt: When producing hard disks, the manufacturer has a built-in automatic detection function in the hard disk. When a computer hard disk has a physical failure, this function is used to alert the computer user that there is a potential physical failure in the computer hard disk, which may lead to an abnormal normal operation failure.

2) Initialization crash in Windows: If there is a failure of the hard disk of a computer, it is likely to cause the computer to boot the initialization and fail to pass normally.

3) Although the computer can enter the Windows system normally, an error message pops up when it is running, and the computer stops or even freezes when performing a disk scan. This glitch can be caused by software.

4) Run the built-in disk scanner of your Windows system and find errors or even bad ones.

5) The hard drive is not recognized in the BIOS, and even if it does, the operating system cannot find the hard drive. In this case, the hard drive has a serious failure.

Second, the cause of the failure may be as follows:

1) Hard disk cooling fan: Some low-grade fans vibrate quite obviously, vibrating on the hard disk, which will affect the life of the hard disk in the long run.

2) Optical drive: The current mainstream optical drive reading speed has reached more than 50 times the speed, when the optical disc in the optical drive rotates at high speed, the vibration emitted by the optical drive itself will lead to resonance, which affects the work of the hard disk.

3) Dust: The damage of dust to the hard drive is obvious. Dust deposited on the hard disk circuit board can seriously affect the heat distribution of the circuit board chips, causing the board components to rise in temperature, causing the chip to overheat and burn out.

4) Static electricity: When maintaining the computer, many people hold the hard drive, and when the weather is dry, tens of thousands of volts of static electricity will accumulate on the hand, and the static electricity may break down the circuit board chip on the hand, resulting in the failure of the hard disk.

5) Low-level formatting: The damage to the hard disk is very large, which may lead to the spread of hard disk badness, and even lead to the loss of hard disk parameters, resulting in the hard disk being unusable.

6) Power supply: A low-quality computer will make the hard disk be disturbed by voltage fluctuations, especially in the read and write operation of the hard disk, if there is a power problem, a hard disk can be scrapped in an instant.

7) Magnetic field, because the hard disk is a device that relies on magnetism** to record data, if the outer ring of the magnetic field is conditioned, it may lead to the loss of hard disk data, so you should try to stay away from the magnetic field environment.
