Operating system problems can also cause bad sectors. But, over time, even those sectors that hold information can become bad. Usually, the operating system tries to exclude the dead sectors from its work by marking them as faulty.

A large number of bad sectors – caused both by a sudden power failure and by aging magnetic disks.

Manufacturers try to minimize the effect of vibration on hard drive performance, but in one way or different, shocks and hits will have an impact on the hard drive

Accidental dropping and other mechanical damage – hard drives are less reliable than flash drives and solid-state drives due to moving parts.

The thing is that during failures or virus activities the hard disc may be supplied with more power than necessary which leads to hard disc overheats and premature failure

Hard disc overheating – most often caused by viruses and other problems with the operating system.

Accordingly, the more often the power supply is suddenly cut off, the more bad sectors will be on the disk and the lower the lifetime of the hard disk will be Under normal conditions, however, the read-heads are first in place before the power is turned off. If the power is suddenly switched off, although the read-heads start to return to their place due to the control mechanism, they do not always have time and may touch the disk’s surface. It is achieved by the airflow caused by the rotation of magnetic disks. The fact is that the read-heads “hover” over the magnetic disks at a distance of several microns.

A sudden power failure also greatly affects the controller, the reading heads, and the surface of the magnetic disks which make up the hard disk.

Otherwise, the data may be irretrievably lost

The process of replacing the controller is quite complicated and expensive since you need to find an identical model, as well as to flash it so that it knows how to read data from the surface of the disks correctly. Most often, voltage fluctuations are caused by electrical problems or failures in the operating system. Voltage fluctuations – very much affect the hard drive controller, which distributes information over the surface of magnetic disks.So, the main causes of hard drive failure are: It will help you better understand how to prevent failures, as well as how to prolong the life of hard drives. Let’s start by looking at the main causes of hard drive failure. Causes of hard drive damageĪ hard drive is a very reliable device, but due to its construction features, it can also break down. That’s why it’s important to know how to correctly maintain your computer or server hard drive, and how to recover important data if it fails. Larger companies store their data on servers, which in turn are also built on hard drives. A photo from a wedding, an important report you have worked on for weeks, or a secret project of your company – all this data is stored on your computer’s hard drive. In the case of regular users, most often it is a computer hard drive. And all this valuable data is stored somewhere. All this led to the fact that the value of data began to grow dramatically and is often measured in a few thousand dollars for regular users, and hundreds of thousands of dollars for large companies. So tightly that today there is no a day when a person does not use electronic devices and work with information in one way or a different – from simply surfing the Internet or watching Instagram stories to making digital purchases in online stores. Information has entered our lives tightly. How to recover the data from damaged drive?.But what do you have to do if the disk is damaged or unreadable? How not lose information? In this article, we will find out how to recover data from a damaged hard drive. The hard disk is one of the most important components of a computer since it stores information that is important to the user.
