The computer hard disk is broken, what is the fault, as the title Thank you

I don't know if the landlord asks about the hard disk damage is hardware or software, the software damage will generally occur, file loss, capacity size display error, partition loss, program operation is not normal and other phenomena. If the hardware is on, there is generally an abnormal sound of the active motor of the hard disk, an abnormal sound of the servo motor of the magnetic head, a power-on and boot display that the hard disk or the hard disk partition with boot data cannot be found, abnormal entry into the system, abnormal file reading and writing, etc. Generally speaking, the hard disk is a relatively durable part, and the probability of physical damage to the hardware is not high, but this is a delicate thing, and the distance of the head suspended on the platter is calculated in microns, so it is particularly afraid of vibration, and the violent vibration will cause the head to hit the platter, resulting in disk data loss and physical damage.

Relatively speaking, the probability of software failure is much more, such as misoperation, sudden power failure when the disk reads and writes files, virus invasion, etc., which will lead to the soft failure of the hard disk.

Let's check your hard drive first! As for what is the performance of the break, there is generally an abnormal noise, difficult to read, easy to crash, and in serious cases, the machine will not be able to be opened! If it's a minor problem, there are a few bad sectors!

But generally if there are bad sectors, the hard disk should be replaced as soon as possible, because the bad sectors will continue to increase!

Hard disk is the most vulnerable part of the computer, damage is not fatal, generally damaged after the computer can not operate normally, generally can not enter the system, after entering the system there will be an inexplicable crash, the crash can not be recovered. If the damage is fatal, then the drive is undetectable. The hard disk is not easy to repair, and there is generally no need to repair it when it comes back.

1.First of all, there is a high risk of making an abnormal noise. 2.It will run very slowly, and it will even crash from time to time. 3.Won't start. Can't get into the system. The message indicates that the hard disk cannot be found or that there is no system on the hard disk. Wait.

Don't reboot! If there is a bad way! You're done!

If you have important data, go find a place to fix it! Let's go to Beijing! There's a company called Flyer that specializes in repairing hard drives!

The fee is more expensive! If there is no important data! Find a computer repair shop!

Let it partition you and redo the system!

The most straightforward thing is. I can't find the hard disk and can't enter the system.。。 Which one are you?

The most common bad hard drive is bad sector repair, if it's too expensive, it's better to buy a new one.

There are 5 situations that can occur when a computer hard disk is broken:

1. The system displays a blue screen and prompts a related error**.

There are three types**, and they indicate physical damage to the hard drive, such as sector corruption, firmware corruption, or head corruption.

2. The BIOS does not recognize the hard disk.

There are many reasons why a hard drive cannot be recognized, and common faults include bad sectors, corrupted firmware, malfunctioning head motors, and burned circuit boards.

3. The hard disk emits an abnormal sound.

This is the most intuitive symptom after a damaged head. Ordinary hard drives also have this sound, but the sound is low. Under normal circumstances, the sound of a damaged disk can be heard clearly when the head is damaged.

4. The hard disk sends out a "Didi" alarm.

In this case, an alarm sound is generated as the head does not return to the landing zone and is parked on the hard disk. The motor is locked and the hard drive stops working.

5. The hard disk does not rotate or stops after a few seconds of rotation.

Generally speaking, there are several common signs of a hard drive failure:

1. The hard disk indicator is always on or not on at all, and the system cannot be entered after booting, indicating that the system cannot be found or the hard disk cannot be found.

2. The hard disk indicator light is always on, even if the system has just been reinstalled, it will prompt that the file is lost and cannot enter the system after restarting or shutting down.

3. In the process of daily use, it crashes frequently and fails to start the system.

4. You can hear the obvious abnormal sound of the hard disk during power on/off or use, such as "click" or "squeak" sound.

5. When reading a certain data or running a certain program, the hard disk repeatedly reads the disk and makes an error, prompting information such as data damage, or it takes a long time to succeed, and sometimes even a blue screen appears.

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

7. The system cannot start normally when virus infection is ruled out, and prompts such as "sector not found" or "general error in reading drive c" appear;

8. When the information is hard disk, it stops moving forward to a certain progress, and finally reports an error and cannot be completed;

2.Use a professional tool: If the hard drive fails, you can use a professional hard drive repair tool to repair the eraser. This tool can detect faults in the hard drive and fix them.

2.Circuit faults: Circuit components in hard drives are also prone to failure, such as power supplies, capacitors, etc. This failure usually results in the hard drive not being able to power or read data properly.

3.Replace the hard drive: If the hard drive cannot be repaired, then the hard drive needs to be replaced. When replacing a hard drive, you need to pay attention to the model, capacity, and interface of the hard drive to avoid compatibility issues.

3.Logical faults: Logical components in hard disks, such as partition tables and file systems, are also prone to failures. This failure usually results in the hard drive not being able to recognize or read data properly.
