There are situations in which the storage units can be damaged, that is why this article will explain the process of repair bad sectors of hard drive.
Bad sectors where various data is stored
Repair bad sectors of hard drive
Hard drives are devices that are responsible for storing a large amount of data and files that are in the operating system, so they are essential in computers. This unit is made up of a wide range of sectors so that the corresponding information can be stored in each of them.
But there is a problem when a sector or sectors of the device are damaged, as it does not allow the saved data to be read and the possibility of writing to it is not lost. So this inconvenience is very serious for users, especially when the stored files are important.
There are the types of bad sectors in a hard disk, first you have those that are physically damaged and the second type is logically damaged. These cases are the ones that generate problems in the reading of data and files, this situation being very worrying for any user.
Due to this, it seeks to repair the damaged sectors of the hard disk, first it must be known that when the failure comes from physical damage it cannot be repaired, the only solution is to obtain a new storage device and install it in the computer so that it runs the functions smoothly but the data stored on the faulty hard drive is lost.
On the other hand, if the damage is logical, there are methods to solve this damage, but it must be remembered that a procedure will be carried out in the system in which if it is not executed in the correct way, the storage unit will not be able to be recovered. , so it is the responsibility of the user of how the process is applied in the device system.

How to identify when the storage unit is faulty?
Hard drives have sectors that constitute a series of bits of data and information of the system as well as of the installed applications, in this way there is a greater organization and management of them. Another way of saying it is that it has sectors where it stores the data of each program and that the computer executes when the system starts up or when the user requests it to be read.
When one of these sectors gets damaged these files and stored data cannot be opened. As explained previously, there is the possibility of having two failures, physical and logical. The physical damages cannot be fixed but the logical ones can apply a procedure so that the device can function in a normal and optimal way.
But first it is advisable to know that the unit is defective, since a first symptom is when the stored data cannot be read which can also be caused by other problems and not necessarily by the damaged sectors, there is a process that allows highlighting if the hard drive has bad sectors.
If the Windows operating system is used, the CHKDSK tool can be used in the execution of the CMD window as an administrator user, with this it is possible to check the status of the hard disk. It is important that before starting this process the hard disk must be offline and it cannot be the operating system disk either.
The program is in charge of carrying out an analysis on the disk so that it reports the errors it has, then the command chkdsk (drive letter): / F must be executed. Then the system will automatically apply the necessary fixes to repair the bad sectors of the hard disk.
Repair methods
When having a storage unit with bad sectors, the first thing to do is certify that this failure is logical and not physical, so that various methods can be applied to solve this problem of data loss, you must also buy that the disk has this fault applying the procedure explained in the previous point.
The first thing that should be done is a backup of all the data that is stored on the hard drive, mainly in the sectors that are defective so that the recovery of this data can be guaranteed even if it is through other storage units that is available.
First method
With this method, the first step is to go to the "This computer" menu that the system has, select the unit to be repaired and right-click it with the mouse, in which a list is displayed. options and you must choose the one that says "Properties", this will open a window with several tabs.

This method is characterized by executing a few simple steps so there is no possibility of damaging the storage unit.
Second method
To repair the damaged sectors of the hard disk that appear again, this method must be applied, which consists of executing the professional program Wondershare Liveboot, being a software specialized in this type of failure and more when the computer cannot boot in a normal way.
First the program CD must be inserted, the system is accessed to run automatically, then a series of options is displayed where it must be selected in "Windows Recovery". Then click on "boot failure solution" and on the solution tab to execute "method 2" which consists of repairing the bad sectors of the hard disk.
