How to recover bad sectors on disk. Recovery of bad sectors. What are bad sectors

  - one of the most important components of the system, with the breakdown of which, all user information, system files and data may be lost accounts. In this regard, it is necessary to use only reliable HDDs, to be able to handle it correctly and to know what to do when it breaks down.

Causes of Failures

Depending on the reason for the failure, you need to search the program. Two similar programs can solve completely different problems, so you should deal with what crashed the hard drive.

How to restore sectors using programs

If your computer cannot boot normally, it may be best choice. In the "Solution" section, find "Method 2", which allows you to run a disk scan to repair bad sectors. After completing the check and repair, restart the computer and you will not have to fix it again the next time you use the computer.

Part 2 How to recover data from an external hard drive

If you can’t recover well bad sectors, and you did not back up the data on your hard drive. But you want to recover data from external hard  drive, in which case you can try the external recovery program hard drive.

List of the most common problems with HDD:

  • bad sectors;
  • damage;
  • wear;
  • software failures.

If the damage occurred as a result of a long service life or excessive external mechanical stress, then it will not be possible to help him with the help of programs, but if the reason is a software failure, then it is possible to cope with this problem.

Step 2 Select the section where you lost your data. Step 3 All partitions on your hard drive will be detected and listed. Alternatively, when you open the Power Users menu, you can use the mouse or trackpad to select the Command Line option. You can verify that you have successfully granted command line administrative privileges by making sure that “Administrator: Command Prompt” is present in the window title bar.

Programs for Windows that can "cure" the railway

To summarize, the complete command that should be entered in command line. If, however, the target drive is boot disk, the system will ask you if you want to run the command before the next boot. Enter “yes”, restart the computer, and the command will be launched before the operating system boots up, which will allow it to get full access to the disk.

Programs for Windows that can "cure" the railway

Regardless of the task that confronted the user, there are many programs created to solve problems with hard drive   and which today can be downloaded for Windows. List of the best of them:

  • Viktoria;
  • CheckDisk
  • R. Saver;
  • GetDataBack;
  • acronis products and similar utilities.

The good news is that there are various utilities for solving problems with HDDs on the Internet. a large number of . In this regard, their prices are not very high and there are many free analogues. It is also easy to find a utility in Russian.

However, once this is done, he will present a summary of the results, including total disk space, byte allocation, and most importantly, any errors found and corrected.

This is expected behavior, and this means that these sectors and any data potentially stored on them have failed, even if you or your operating system have not yet realized this.

Getting started with the scanning process

Get tips, reviews, news, and giveaways designed exclusively for subscribers. Recovering data from a hard disk image. Later you can select these disk image files and process them with data. The advanced built-in algorithm of this software helps to clone sector by sector of your hard disk to create a disk image file. Useful Scenarios software  for image processing.

Viktoria

Viktoria utility created by Belarusian developers for operating windows systems. It is considered the most powerful and can perform many different actions with a hard disk, such as testing, treatment, scanning for software errors and identifying bad sectors that arose as a result of physical damage. The interface language is Russian, so Russian-speaking users should not have complications in managing the program. It is worth noting that the program can be downloaded for free.

Hard disk with bad sectors. If there are bad sectors on your hard drive, it will be very difficult to access any stored data from the hard drive. In such cases, you can create a disk image file of your hard drive on another healthy hDD, later you will be able to access your data using these disk image files.

Reinstalling the operating system. You can format the disk and reinstall the new operating system, and you may forget to back up all important data from the disk before formatting. But you can restore data from a previously created disk image file.

One of the most interesting features is HDD testing. You can start testing in the program on the “Test” tab. After the test is launched, you can see the statistics of the disk. It includes: the number of checked sectors, slow sectors and bad sectors. By selecting any sector, you can find out how much the delay in its response is. If a bad sector is found during the test, the user may be asked to try the procedure of reassigning the sector from the reserve or try to write to this sector.

Data recovery using a disk image. When you recover data from a hard drive that has bad sectors, during the recovery process, the recovery software will not be able to access deleted and lost data due to bad sectors. In such cases, you can create a disk image file on your hard drive, and then you can easily recover data from this image file.

Video: HDD - “treating” bad sectors

You can use this computer to create a disk image file and to restore data from a created disk image image. Hard drives often fail and make it impossible to access the data that was available on it. This may be due to logical corruption. system files  or due to bad sectors.

The main goal of this program is hard disk treatment, namely the restoration of bad sectors of the hard disk through magnetization reversal. It is almost impossible to do this with conventional programs, but users notice that after treatment with this program, bad sectors become smaller or they disappear completely.

What is "regeneration", acquaintance with the program

When you see blue screen  or when your hard drive takes forever to boot, it is likely that your hard drive has severe logical corruption or bad sectors. In this situation, your hard drive can be called unsuccessful or about to fail.

When the flash drive is damaged, you will see messages like “Format Now” due to file system corruption. If you have important photos stored on a flash drive, and you format them by mistake or even otherwise, you can restore data from it. Read this tutorial to understand how to recover photos from a damaged flash drive.

"HDD renegator allows repair bad sectors  hard drive without data loss. The program supports a large number of types of railway, as well as all file systemsincluding: fat32, NTFS, ext and so on. Unformatted disks are also supported, ”- these are the assurances of the developers, which you decide to believe or not.

The main function is to test railway  for errors and bad sectors. During the scan, you can pause the process and see the statistics. However, there is little useful: the number of checked sectors and sectors with a delay. Surprisingly, the program is paid, but most free analogues provide the user with much more information about the scanning process, which, in turn, allows you to more accurately determine the status of the disk.

This software can recover partitions deleted or lost due to formatting or partitioning errors. It is commonly referred to as one of the causes of a slowdown in the computer or a hard disk failure. The bad sector is permanent damage to the hard drive, which, by the way, stores your data. If any data is written to a bad sector, this piece of data is no longer available.

Because bad sectors are a physical anomaly of a hard disk, the causes are also physical in nature. Default hard disks  have bad sectors that are already fresh out of the box. Although manufacturers hard drives  can completely eliminate bad sectors, procedures and resources consumed will make it impossible to sell hard drives at the current low price.

The main function of the program called "Regeneration", in addition to the fact that it does not work in 100% of cases, can also fully delete data from device. Given that the program can be downloaded only for money and only for the Windows operating system, we can conclude that this is not the best option for railway.

R. Saver

One of top programs for the treatment of ID according to most users. The utility uses the advanced scanning method, which can help restore files even after several formats. Works with both hard drives and SD cards. Such recovery takes a lot of time. It will take more than 4 hours to check a 250 GB HDD, recovery of SD cards takes even longer. Despite the length of work, the program is popular and has established itself as a reliable utility for Windows.

Physical shock to your computer can affect your hard drive. When this happens, there is a chance that damage to the hard disk may occur, leading to bad sectors. Such damage can lead to a head crash when the hard drive is running.

What are bad sectors

High temperatures resulting from widespread use, poor ventilation, or poor operation of your computer system can also lead to bad sectors. This is due to the fact that hard drives operate on the principles of magnetism.

Healing a hard disk using Windows 7 system tools

You can run the HDD check on windows 7, in the properties of the selected drive. You can open properties by right-clicking on it. Then, following the menu prompts, select the check and troubleshoot the drive. You can also check the disk through the command line (to enter it you need to type cmd in "Run"). At the command prompt, enter chkdisk. In the menu that opens, select the check again and auto recovery  disk errors. At the end you can see the result.

Bad sector on the hard drive

Or, bad sectors can simply form over time, as hard drives lose their magnetic properties. This is a “natural” degradation of the hard drive, and users should be aware of this and replace their hard drives when they have been used for a certain period of time.

Over time, manufacturers will try to collect as much data as possible on one dish, increasing the density of data on the hard drive. Superparamagnetic limit in hard drives  is the limit set for the storage density of hard drives due to the particle size of the magnetic elements on the plates. With increasing data density on the tablet, the failure tolerance decreases.

Such a check should be carried out before contacting third-party programs, since it is the safest. Before starting a program that could harm the hard disk, it is advisable to try to copy important data from the disk.

Although bad sectors are a physical anomaly on the hard drive, this does not mean that you can physically see it. Instead, there are several applications that can allow you to detect bad sectors. This application can perform both quick and full surface scans. It is free and does not require installation.

Hard drive recovery

In addition, some hard drive manufacturers have their own hard drive utilities, where their application scans the hard drive for any problems. Backing up hard drives. Bad sectors can make your computer almost unusable, crash left and right and prevent access to your data and backup  data.

We recently spoke to you, and today we’ll talk about restoring bad sectors. Even the most reliable hard drive starts to crash over time - it works slowly, “loses” folders and files, makes strange clicks, starts checking itself with every boot of the operating system. Such symptoms in most cases mean one thing - the so-called bads appeared on the hard drive - damaged sectors. This can be caused by the activity of viruses, logical and physical defects.

If there is critical data on the hard drive, you need to quickly transfer the data to another hard drive before the drive crashes and your data is deleted along with it. However, you need to check if you have suffered only from bad sectors, and not from physical failures.

Get external drive  to back up data. However, you need to get a hard drive that is at least the same as the old drive. First you need to install the hard drive as additional disk. Remove it from the computer and install it on another computer.

You don’t need to panic and run to the store for a new drive - in most cases, the situation can be corrected by repair damaged hard sectors  drive.

This procedure is performed by means of the operating system or by third-party programs, and is a remapping (rewriting) of bad sectors by the free ones embedded in the hard disk design by the manufacturer specifically for such cases.
With minor malfunctions in the hard drive, you should try to “repair” the bad sectors with standard Windows utilities CHKDSK  and SKANDISK. To do this, open the “My Computer” folder, select one of the logical hard sections  drive, call the context menu and go to the "Properties" item, then open the "Tools" tab and click the "Run Scan" button.

Download, unzip and run the application. From the tool menu, select “copy files”. Select the source location and destination location and click “start copying”. Why do we need software? Firstly, the software has a built-in function in which even if parts of the file are damaged due to bad sectors, it will search for neighboring sectors to determine the degree of blocking of bad sectors, and automatically count how many attempts are required and reduce the number of repetitions per blocks bad sector.


A window will open in which you need to check the box next to the Scan and repair damaged sectors item, and then click "Run."


As soon as he does this, he will restore all readable bits of the file and add them to save your data, so at least some parts of the file will be restored. It is still much better than everyone. The application also has the option “Copy auxiliary folders”, where it scans the entire directory and tries to copy everything you need.

Programs for recovering bad hard drive sectors

“Copy Files” works well if you want to copy only certain files and folders, and not the entire drive. If you want to copy the entire disk to a new one and do not want to reinstall the operating system. Then simply select the source drive and destination drive.

Will begin recovery of damaged hard disk sectors. This procedure must be done with all logical partitions of the hard drive; sometimes it will take a reboot to complete verification and recovery.
If work with bad sectors  hard drive standard windows tools  for some reason the user is not comfortable, then you can turn to third-party programs.
For example, use the Victoria utility. It is worth noting that its effective operation is possible only when running in a DOS environment - for this you need to create a bootable USB flash drive or disk with victoria program, restart the computer and set this drive as a priority in the BIOS. After loading DOS, you need to start Victoria, select the desired hard drive in the program and start the surface test by pressing the F4 key. Moreover, if it is already known for sure that there are badges on the hard drive, you can immediately select the function for rewriting them - “Classic REMAP”, after which the user can only wait until the recovery of damaged sectors of the hard disk is over.
Another one program  for working with badges - Mhdd. It is also desirable to run it in DOS mode from a bootable USB flash drive or CD.

If you are lucky, you will restore backup of almost everything on disk. However, if you wait too long backups  data on a heavily infected disk, some data may be damaged and inaccessible. Do you know how to recover data on a hard drive with broken sectors?

Data not available on hard disk with bad sectors

Have you ever encountered the data loss needed to recover data to a disk with bad sectors? Yes, there are broken sectors on my hard drive. operating system  reports that some sectors on the hard disk are damaged for unknown reasons. And some data on the hard drive is no longer available. I need a safe and effective solution to solve this problem. If you know how to recover valuable data from a hard drive with broken sectors, please help me!


MHDD implements low-level formatting hard  disk with erasing the damaged sectors, so you need to consider that during the procedure all information will be deleted from it. To perform the bad recovery process, you need to boot the computer in DOS mode, start MHDD and type the “Erase” command, which will format it. After that, you need to type the “Remap” command here in the program - it will automatically scan the hard drive and replace the damaged sectors with the backup ones.
