What are the symptoms of hard disk failure

Generally, we are more aware of the system failure, black screen and blue screen, etc., and sometimes it is not because of system failure but hardware damage, such as hard disk damage, how to judge this? Hard disk is the most important device of the computer, It is like a large warehouse, which stores our most important data, and it has the advantages of large capacity and fast speed. We store important data files for daily life and learning on the computer hard disk, but once the hard disk fails, the consequences will be unimaginable, so we must maintain it in normal use.

If the hard drive fails, it's best to find it early and take the right action in time. If you wait until you get sick, the valuable data on your hard drive is hard to escape. Generally speaking, there are several performances before the hard disk fails:

1. The S.M.A.R.T fault prompt appears. S.M.A.R.T. is “self-monitoring, analysis and reporting technology”. It can monitor the head, disk, motor, circuit and other components. The monitoring circuit of the hard disk and the monitoring software on the host computer analyze and compare the operation status of the monitored object with the historical record and the preset safety value. Once the safety value range appears. In other cases, it automatically warns the user. More advanced technology can also automatically reduce the running speed of the hard disk, transfer important data files to other security sectors, and use S.M.A.R.T. technology to effectively predict the potential failure of the hard disk and improve data security.

2. In the BIOS, the hard disk cannot be recognized from time to time, or even if it can be recognized, the hard disk cannot be found by the operating system. This is the precursor of the physical failure of the hard disk, so the data should be transferred out immediately. Carry out inspection and repair.

3. Can enter the Windows system, but the running program error, while running the disk scan can not pass, often slow down or even crash when scanning. This phenomenon may be a problem with the hard disk, but it may also be a soft failure of Windows for a long time. If the possibility of setting problems on the software side is ruled out, it is sure that the hard disk is faulty.

4. Can enter Windows, run the disk scanner directly to find errors or even bad sectors, this does not need to say more, Windows check program will report the situation in detail, it is recommended to use the efficiency source hard disk detection and repair program Repair and isolation.

5. Crash when Windows initializes. This situation is more complicated. First, the possibility of problems with other components should be ruled out, such as poor memory quality, fan overheating, system corruption, or virus damage. If it is determined that the hard disk is faulty, it will be processed separately.

Never give up reminding you: We usually have a good habit of backing up important data at any time, so that when the hard disk fails, it will not be lost. In addition, some of the most important data is best backed up to the disc, so that it can be more foolproof.

If you have a problem with your computer, but you don't know whether it is a software or a hardware problem, if you suspect that it is a hard disk problem, then you can judge according to the symptoms provided above.
