Is my hard drive damaged? Under what circumstances can a hard drive break?

The voltage is unstable, and it is easy to cause damage to the hard disk.

If there is a rustling sound, it is not necessarily that the hard disk is broken, but it means that the life of the hard disk is almost (it can be used) Once the hard disk is used for a long time, there will definitely be a rustling sound. When playing games, the hard drive runs fast, and it is inevitable that there will be no rustling sound.

The hard disk is more than 5400 rpm or 7200 rpm when it's running at such high speeds.

If you lose power suddenly, or shut down abnormally, it may cause damage to the hard drive.

In this case, I recommend that you buy a UPS uninterruptible power supply, no more than 200 yuan.

And it plays a decisive role in the security of the computer.

So I don't advise you to lose a big one.

If there is a UPS, if there is, there is no voltage problem, if not, since the voltage is unstable, it is time to confirm whether the voltage is stable and there is also this problem.

You said that at the same time, the system often restarts, this situation is mostly caused by voltage instability, the hard disk should be fine, the hard disk has a rustling sound, and it is normal during the frequent reading and writing of the hard disk, but the computer is not starting, and no program is executed, and it is not normal to copy things without **. It is best to use the computer under a regulated voltage, or install a UPS regulated power supply.

If it's not very loud, no problem. My Seagate 80g has been ringing for half a year now.

Generally speaking, the damage of hard drives can be divided into hard damage and soft damage according to the broad categories.

Hard damage includes four types: head component damage, control circuit damage, comprehensive damage and sector physical damage (commonly known as physical bad sectors).

Damage to the head assembly: It mainly refers to the situation that a part of the head assembly in the hard disk is damaged, causing some or all of the heads to be unable to read and write normally. There are many ways and possibilities for damage to the head assembly, mainly including dirty head, head wear, head cantilever deformation, magnetic coil damage, displacement, etc.

Control circuit damage: It refers to the broken circuit or short circuit of a certain part of the electronic circuit board of the hard disk, or the damage of some electrical components or IC chips, etc., resulting in the hard disk can not start normally after power-on, or the magnetic head can not seek correctly after the hard disk is powered.

Comprehensive damage: It mainly refers to the problems caused by some small changes in the hard disk. Some of the hard disks are aging due to heating or other relationships during use; Some of them are due to small changes or displacements in the shell or disc surface or motor spindle after the hard disk is shocked; Some are due to the fact that the drive itself has a thermal, frictional, or structural flaw in its design.

There are various reasons that lead to the instability of the hard disk, often losing data or logical errors, working noise, slow read and write speed, sometimes working normally but sometimes not working properly, etc.

Physical Sector Damage: Refers to the physical damage to the disk surface caused by collision, head friction or other reasons, such as scratches, magnetic loss, etc.

Soft damage includes track servo information errors, system information area errors, and sector logic errors (also commonly referred to as logic bad sectors).

Track servo information error: It means that the servo information of a physical track is damaged or invalid, resulting in the physical track being inaccessible.

System information area error: It means that the system information area of the hard disk (a system reserved area inside the hard disk, which is divided into several modules, which saves many factory parameters, setting information and internal control programs of the hard disk) cannot read the information of some modules or the verification is abnormal when the power is self-tested, resulting in the hard disk cannot enter the ready state.

Sector logic error: The sector becomes invalid due to verification errors (ECC errors and CRC errors), sector flag errors (IDNF errors), address information errors (AMNF errors), and bad block marking errors (BBM).

What should I do if my computer's hard drive is broken? 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. So how do we recover files formatted in this case? How can I get my lost files back?

Step 2: Select "Where the original data file is stored", here you can directly select the disk where the corresponding data was deleted by mistake, and click the "Start Scan" recovery option below to automatically scan.

Step 3: After the scan is over, you can select the files we need to recover according to the file path or file type, and click the "Recover" option below to retrieve the lost files.

The above is an introduction to the relevant methods and skills of data file recovery after hard disk formatting, I believe you also have a certain understanding. In order to be able to retrieve the lost files, we can repair the data loss in turn by following the above steps, and at the same time, we also need to avoid the data files being overwritten.
