How to restore the hard disk operation. Free hard disk repair programs. Other possible hard disk resuscitation options

In this article we will talk about the restoration of the battered sectors of the hard disk and the reasons for their appearance. Step-by-step instructions will help you prepare for this procedure and can cope with it.

What is broken sectors

Let's briefly consider the structure of the hard drive. It consists of several separate discs over which magnetic heads are located for reading and writing information. When saving data, the head magnetizes certain disk areas, divided into tracks and smaller components - sectors. It is in them that the units of information are stored. If the sector becomes unavailable for reading - it is called "broken".

Several signs are indicated about the appearance of such a problem:

screenshots, grinding, tapping when the disk is working;
the heating of the HDD surface (in the normal state of this should not occur);
frequent errors when working and starting the operating system.

Typical reasons

The main causes of the appearance of broken segments of the Winchester are:

Also, hard drives may appear due to mechanical damage. It often leads a drop in a hard disk or computer, leading to damage to the magnetic surface (for example, during transportation). There are non-working parts and because of the factory marriage. In this case, they may not appear immediately, but "sprinkled" over time, rapidly increasing its quantity to a critical level.

Important! In the event of suspicion of mechanical damage or marriage, it is worth directing to specialists or exchange Winchester under warranty.

Restoring Bied Sectors HDD With Victoria

If the appearance of broken segments is associated with software failures, they can be restored using a specialized software. One of these programs for restoring the battered sectors HDD is Victoria. The utility is available in two versions - for Windows and DOS. The most effective will be restored via DOS, since when operating OS, some sectors can be occupied, and therefore are not available for scanning.

Victoria HDD - Diagnostic Program

Scanning

To start work, we will need to carry out a small preparation. First, you will need a disk with the program written to it or the boot flash drive. If everyone can cope with the image entry, then difficulty creating a flash drive may occur.

Let's focus in more detail at this step:

Note! The program takes very little space, so after installing it, the drive can be used to store other information. To accidentally not delete the files you need to work, it is recommended to select a separate folder for them.

We proceed to the scanning process:

Here we need an item "Reallocated Sector Count"which displays the number of fragmetics in the reserve zone as well "Current Pending Sectors"where parts are displayed that it is impossible to read. If their number is not very high, then the disk is subject to recovery.

Hard disk restoration

Let's deal with how this process is happening. Problem segments can be divided into two types. The first are not read due to the incompleteness of the information stored in them and its checksums.

This error occurs when feeding with nutrition, when new data has already been recorded, and the checksums remained old. They simply cease to be recognized and restored quite easily - their formatting and recording of correct amounts.

The second type arises as a consequence of mechanical damage. In this case, the restoration is more difficult, but still possible. The resumption of the performance of such parts is carried out by using the backup areas that are on each Winchester.

We start recovering each of these error types.

Video: HDD - "We treat" broken sectors

First, we will try to correct the broken sectors by erasing the information stored in them:

click F4 and get into the check menu;
in the selection selection menu with unreadable sectors, specify "BB: ERASE 256 SECT" and press "ENTER".

The long-lasting scanning and restore sectors of the HDD will start. If the program finds a defective sector, it will try to erase it, thereby configuring the error. If there is a mechanical defect, then an error will be reported. In any case, it is necessary to wait for a complete end of the check and then separately correct the sectors with physical malfunctions.

For this:

Now the recovery operation will work on a different principle, trying not to wash the spoiled sectors, but to replace them with space from the backup area.

Important! If there are a lot of such sectors, the backup space may end. This will report this special message, and further recovery will become impossible.

After successfully restoring the battered sectors on the hard disk, it is recommended to fully check the file system for errors.

You can do this with the help of the chkdsk utility or the following way:

Photo: Verification of disk for errors

Attention! So that the system not only has found, but also corrected the problems, select "Automatically correct system errors" before starting scanning.

The methods described above will help to easily cope with non-critical cases of the appearance of problem sectors, find and correct them. Exactly following our instructions, any user will be able to do it independently, not even possessing computer education. We hope that this information was useful for you.

Repair hard disk (or HDD - Hard Disk Drive) - The procedure for bringing the HDD to the working state, in which it is possible to consider the necessary data from it, including the service information, the file table, user data, multimedia information, etc., even if the BIOS does not see the hard disk. In this article, you will learn how to fix a hard disk, if possible, and what to do if the HDD is not defined in the BIOS or when trying to load the operating system an error appears.

What to do if suspiciously snaps hard disk

Clicks during HDD work is another characteristic symptom when the hard disk does not start and, accordingly, is not determined by the system. The reason, as a rule, is the wear or breakage of the hard disk heads. Like any other mechanical breakdown of HDD, it is impossible to fix with your own hands.

However, if you hear clicks on a hard disk (that is, it reads normally and records files), then you need to urgently take certain measures and reinsured. Be sure to back up the valuable information to another hard drive, a flash drive or cloud hosting, the benefit that in our time it is not at all expensive procedure. After all, at one moment it can happen that the hard disk will not start or stop determined - and if you made a backup, then the loss of information will not cause shock.

Repair of a hard disk with failed ROM and damage to the service information (BIOS does not define the disk)

What if the BIOS does not see the hard drive? The HDD, which has occurred similar errors, has characteristic symptoms: it is not defined in the BIOS, can also produce noise of a strange character (click, tapping). In some cases, the hard disk is available in the BIOS, but it is not capable of loading the operating system.

Accordingly, to restore ROM and service data on HDD, the correct operation of the above-mentioned components of the hard disk will be required. This type of repair is made by experts on special equipment. It is impossible to produce it with your own hands. At the same time, the physical structure of the surface of the hard disk is read correctly, so the data physically remain intact.

Are there any ways to restore an external hard disk from internal?

Answer. Definitely no. The filling of devices is identical, the difference is only in the form-factor storage factor - that is, roughly speaking, in the box in which the filling of the disc is packaged. The external disk is easier to be physically damaged and other risk factors. But they are more mobile and offered the user a convenient connection via ESATA whether another interface is connected to a PC. Thus, this manual, how to restore the hard disk will be useful both to the owners of "traditional" drives and external.

The hard drive stood in a laptop, the system in which stopped loading. Why am I going to format him - but! It was not there, it was, as a "external" disk (I stuffed it into the housing from the external "TRANSEND" 500 GB), it is visible only as a local disk "G" and "F" without any information. All attempts to trigger properties lead to Windows hangs 8.1 on a laptop - in "Drive control" is not visible, HDD Low Level Format too. Tell me, if a hard disk does not work, then how can I get it back to my own hands?

Answer. Try split the hard drive to help (partiton magic), it is advisable to perform low-level HDD formatting, see information on the topic. By the way, in addition to HDD Low Level Format, there are many alternative utilities for formatting. It will not be superfluous to check the operating status of the disc, for this, check the SMART and scan discs using the HDD Regenerator or Victoria HDD.

What if you click a hard drive? That is, it works, but sometimes there is characteristic sounds - that is, clicks. Some moments have freezing, and the operating system freezes, and then dies with the disk.

Answer. In rare cases, the problem is associated with disruption of power contacts and SATA / IDE connectors connected to the motherboard. Therefore, we first advise you to turn off the PC and check the connection with the hard disk. Second - Be sure to back up the data on the disk, since clicks are an unhealthy symptom, indicating that the HDD has problems, and at any time you can expect collapse. The third is to diagnose the disk status, use specialized programs - HDD Regenerator, Victoria HDD Doctor and so on.

If the hard disk clicks and is not determined, the situation is more deployed (I wanted). In this case, the mechanics are already worn, and you will not be able to restore the HDD, it will only help the replacement of the hard disk to the new one.

How to increase the hard disk speed? I have Windows Vista.

Answer. Users of Windows Vista and the above indigestion about the slow operation of the disk subsystem. In practice, copying files is noticeably slower than in XP. Why brakes hard disk? One of the reasons lies on the surface and is easily eliminated. The fact is that by default, the maximum speed of the hard drive is disabled in Windows. Therefore, urgently take action:

Open Device Manager (Win + Pause Break, Link Device Manager).
In the list of devices, find the disk device and select "Properties" in the context menu.
Select the Policy tab and activate the "Enable Hype" option.
To speed up the hard disk, restart the computer.

I reinstalled the system and she stands on PCE SSD suddenly a different hard disk on 4TB stopped determined? Then I went to the computer control further into the disk management there shows the capacity of 3.7 TB and free 3.7 TB, that is, it turns out the disc is empty by 100 percent and there 2 spells! Can you please tell me what you can do?

Answer. Perhaps the problem is related to the failure of the file system table, in such a situation, you can advise the TestDisk utility to restore a partition that is not defined by the system, but contains important information.

I have a NP 620 laptop. Everything was fine, but I started to close the windows and the computer hangs. I thought would go away, 15 minutes went - nothing, the reaction was not on anything. Even software shutdown could not retell.

Turning off the physically with the button, turned on again and on the black screen of the laptop knocked the message: Non-System Disk or Disk Error Replace and Strike Any Key When Ready. After that, the system does not see the hard disk. But when the laptop is turned on, it is spinning, that is, everything is OK with food.

2 years ago I updated the BIOS from the official site. Maybe because of this, the hard disk does not open? But he worked tough, all the time is good. What could be? Help please, here is my hard drive - TOSHIBA HDD2E67 320GB.

Answer. If the problem was associated with the BIOS "Ohm, the OS would not load. Or, at a minimum, the reset to the factory settings could solve something.

Try to start looking for the cause on the surface: the hard disk does not work because it failed. This could occur on a variety of reasons (for example, physical damage or wear - which is less likely). If you can check on the same laptop a similar hard disk, do it.

Recovery of hard drives implies to bring disks to a state that allows you to count the necessary information from them. Repair in cases where data recovery is not required, we are not engaged.

Restoration of hard drives in the presence of unreadable sectors

As a rule, if there is no periodic check of the disk to the BED blocks, their appearance manifests itself in reading errors, the disappearance of folder files. Can be displayed as unformatted or disappear logical disks, the operating system stops loading.
Restoration of hard drives in the presence of unreadable sectors is carried out using a software and hardware complex. This complex allows you to work with discs in technological modes, a multiple reading of sectors and reading with ignoring the control and cyclic code. With these operations, in many cases, it is possible to consider information from a significant part of the failure sectors.
In the case when unreadable sectors were in the area of \u200b\u200blocation of the partition system, or service information information, a pre-removal of a copy is required for a serviceable medium. Then the data recovery passes the same as in the case of a good drive.

Restoration of hard drives with disorders in the ROM or service area

The disc is not defined in the BIOS or is determined incorrectly. May be made of noncharacteric sounds, "knocking". There are cases when the media is defined correctly, but with further loading BIOS issues an error.
Recovery of the hard disk, in this case it is to restore the data of the HDD service zone or ROM. These works are carried out on the stand, in the technological modes of the drives of the drives. After that, data recovery passes as usual.

Restoring hard drives with a faulty controller

At the same time, in most cases, the disk is knocking, or is not defined in the BIOS.
The hard disk restore work is mainly concluded in replacing or repairing the controller. Sometimes it also requires flashing disk firmware. After repair, the data recovery occurs both with a serviceable drive.

Restoration of hard drives in case of faults in Hermone

This type of malfunction most often causes a knock or grind in the humbling. The exception is "sticking heads" and "wedge" of the engine, in this case the disk is not unwound. The drive is not defined or can be determined by BIOS.
When out of failure of one or more magnetic heads, or the switch (it is also located in the Hermbock), it requires an opening of the humbling and replacing the magnetic head unit with the switch to restore the hard disk.
In the case of "sticking", the Hermons and the heading "heads" in the parking area is opened. The engine jamming is eliminated by its repair or transplantation "Blinov" on a serviceable drive.
After that, data recovery is made on the complex

Restore the hard disk of the laptop is often possible even in case of severe damage. The exception is only such defects as the non-standard operation of the engine or head block, that is, a purely mechanical malfunction of the device. Next, we will tell you how to independently cure HDD and eliminate disorders in work related to the failure of the file system or the appearance of defects on the working surface of the disk.

Troubleshooting HDD File System

One of the common faults that the hard disk can get at any time - the file system fails. It detects itself in the inability to open the section, the appearance of the message that the drive is not formatted and it is necessary to carry out this process. If you open the properties of the hard drive, it will be found that the information allegedly is not contained on it.

Hard disk In the event of a file system failure in most cases, you can easily be treated with the standard CHKDSK utility. Working with it is possible directly from the operating environment:

In the "Computer" folder, select the system partition and click on it right-click.
In the window that appears, open the "Service" tab.
A utility checks the hard disk for errors is available here. Click "Check" and set the options you want so that the program can cure all the errors found in automatic mode.

It is even easier to run the same application directly from the command line. This is done as follows:

Open the Command Utility (Win + R) and enter the CMD line.
In the command prompt window, write chkdsk c: / f. The letter "C" here indicates the system partition. If it in your case is designated differently, change the command accordingly.

Checking the system section of the utility is possible only after rebooting the system, which the program will first be notified.

How to restore the logical partition HDD and all its data

Logical sections are better to treat third-party applications, one of which is RS Partition Recovery. The main window here is divided into parts:

all physical drives and logical sections of the system are presented to the left;
the central part indicates the size of the drives, also provides information on their filling;
the directly selected files are displayed on the right, and even hidden data is visible.

Restoring information from the disk using RS Partition Recovery is performed in the following sequence:

Open the recovery wizard, for which you click on the "Wizard" or "Master" button.
In the window that opens, specify the physical drive or the section you want to restore.
Click "Next", after which the application will propose to specify the type of analysis of the selected partition. Mark fast scanning or complete analysis.

Check the last item immediately, without removing the checkboxes in front of the lines below. In this case, the following information will be processed:

All files created in NTFS are defined, i.e. information controlled by Windows.
The FAT system data will also be defined. This type of formatting is typical for removable media, however, the hardbook hard disk may contain such files. With this system, for example, Linux works.
The last point of the deep analysis will recognize all files regardless of the file system.

Restoring the disk data or partition is recommended to produce, cycling three of these filters immediately so that no information disappears. It will only remain to run the analysis and restore the data found. Along the way, you can cure a logical partition, any information is recorded in the future without restrictions.

How to get rid of failed sectors on the HDD laptop

With constant failures in the work and hang of the laptop, there is a possibility that the hard disk has a large number of damaged sectors. You can get rid of them using the Victoria utility. Although this application works from under the loaded operating system, it is usually impossible to treat the disk panel sectors in this mode. From under Windows, the hard drive can only be tested, but get rid of failed sectors is obtained only in DOS mode.

Free ISO-image utilities can be obtained directly on the official website. After creating a boot disk, start HDD recovery:

Run Victoria from the created boot disk. Do not forget to disable Secure Boot if a new Bios UEFI is used in your laptop.
After the selection menu appears, wait a couple of seconds, after which you will be redirected to the download options menu, where to select the item marked with the second number.
In the next window, specify the system Download Victoria in the mobile computers option.
In the application window that opens, click "P" to select the hard disk with which you have to work.
In the HDD port selection window, click on the last EXT item. PCI ATA / SATA.
Check the drive, press Enter, then F9. In the opened window of the self-analysis, you can see the status of the disk. The 5th line indicates the number of blocks that have been reassigned to the existing backup sectors. The number of the latter is limited - when they ends, the information in the Bad sectors begins to be lost. The digit highlighted in red shows that the hard disk state is bad - it must be treated.
Click F4, in the menu that opens, leave three initial items unchanged. The fourth item "Ignore Bad Blocks" can also be changed if you want to simply test the status of the disk. To treat failed sectors, this item must be replaced by BB \u003d Advanced Remap.

In the latter case, the program will try to record in BAD blocks. If it succeeds, the sector will be drawn out from among the failed, which means successful treatment. If the record fails, the damaged sector will be finally replaced by the backup.

The question arising from users how to restore the hard disk can actually be resolved without the help of various computer masters offering for a certain fee to return your hard drive to an efficient condition. Software developers offer several options for restoring broken sectors, which can be used by a person with almost any level of computer literacy.

What is broken sectors?

To understand what is broken sectors, it is necessary to deal with the order of the hard disk and the organization of storage on it.

Winchester consists of several rotating magnetic disks, over which the reading heads move. When recording, these heads magnetize certain parts of the disk, recording information on them. The disc itself is divided into tracks, and they, in turn, are on the sectors.

If information from the disk cannot be read, it is considered broken. The reason for the appearance of such a problem can be an emergency power off, physical disk wear, mechanical effect or overheating.

Depending on the reason, two types of unreadable sectors can be distinguished:

Mind of recorded information and checksum at the end of the sector. It usually occurs when an emergency power failure during the execution of any operation. A similar problem is solved by erasing incorrectly saved information and recording of the correct checksums.
Physical damage to the disk. A more complicated problem resulting from a mechanical impact on the hard drive or its overheating. Damaged sectors are in this case to be transferred to the backup area of \u200b\u200bthe disk, but if there are too many too much, then the data processing speed is significantly reduced.

In any case, to restore the unreadable sectors should try, at least in order to make sure that the hardware is completely inoperable and with a clean conscience, replace it with a new data storage device.

HDD Regenerator.

To begin with, we will understand how to restore the hard disk using a simple, but functional program HDD Regenerator. This utility works with hard drives at a low level, that is, it has monopoly access not only to sectors and clusters of "hard", but also to its mechanisms and controllers.

HDD Regenerator, unlike other similar utilities, does not block access to broken sectors, and tries to restore them by reclamation.

Other programs simply close access to the sector, which leads not only in the loss of information stored on it, but also to a decrease in the volume of the hard disk. Restore deleted files after such a procedure is very difficult. Another question is that such an approach allows you to quickly deal with a non-working disk, but if you have a small amount of failure sectors (up to 100), it is justified to use the HDD Regenerator program.

The last versions of the utility are distributed for a fee, however, you can use the demo version to familiarize yourself with the capabilities of the program. In addition, the HDD Regenerator refers to the type of programs, the fee for which is fought by their functionality and utility.

Working with HDD Regenerator

Load the utility to your computer from the official site. Install it on your computer and, if necessary, Russify (all the necessary files can be found in free access).

Rusification applies only to the program interface. The DOS mode, which occurs the main work of the utility, will still be represented in English, and it is impossible to fix it.

After starting the HDD Regenerator, you will see the window of this kind:

To start testing and subsequent hard disk recovery, click on the top menu "Click to fix". A warning may appear on the screen that you need to reboot and configure the BIOS by setting the SATA controller IDE mode. If these words do not say anything, click "No." It will not affect the performance of the program.

In the next window, the program displays all hard drives connected to the computer. In the "Select Disc" field, you need to click on the Winchester twice to which you want to return life, or highlight it and click the Start button.

The utility will try to run the DOS - the working environment through which direct access to equipment is carried out. Since you are working with a program in the running system, a message appears on the screen that HDDR could not get monopoly access in hard drives.

To correct this error, close all applications and complete the processes running on behalf of the user through the "Task Manager".

Press RETRY; If the error has appeared again, restart the computer and try to complete all tasks performed again.

Another way is to start the system in safe mode, marking it in the download type menu (key F8 when starting the computer). In extreme cases, you can simply click the "OK" button by ignoring the warning. The program will continue its work, but its productivity will decrease slightly.

Restoration of sectors

In the DOS running window, you will see several lines, about the purpose of which you need to say separately. All you will be asked for four options for the program:

When you first start the program, it is recommended to select the item under the number 2. To do this, press the "2" keyboard, and then "ENTER". The following window will appear in which you will be asked to choose the scan order. You can specify a specific interval of sectors, enter the size of the disk or simply start testing from the very beginning.

If you call about it, in which section there is a failure sector, you can try to specify a specific gap. However, it is more convenient to start checking the disk from the beginning to definitely not miss anything. It takes such scanning much more time, but it will be the most complete result.

After selecting the test mode, the disk check will start, during which the number of proven and identified failure sectors will be displayed on the screen. You can stop the scanning process using the ESC key.

The system during the inspection may freeze - this means that HDDR has found fated sectors and tries to determine the degree of their damage.

After the testing is completed, the trial version of HDDR will issue you a message about the need to purchase a licensed copy of the program to continue the recovery of discs. You will be shown the number of detected failed sectors, based on which it is possible to make a decision that it is better to buy a full version of the utility or immediately go to the store for a new hard disk.

If you bought the full version of the program, connect the USB drive - it will be needed in the process of restoring the sectors. After starting the program, select "Self-loaded USB flash drive" and highlight the connected media.

All data will be erased from the drive. Instead, the program will record your files on the USB flash drive by making it loading.

After booting in the DOS system, you will see the same windows as when working with a demo version. This time you need to choose the first option - scanning and restoring sectors.

The recovery process itself can delay for a long time, so if you have the need to pause it, press the ESC key and be sure to wait proposals to exit the program. In this case, the program stopping point will be recorded on the flash drive, with which the scanning will begin with the next time you start. Why these difficulties? In order not to sit in front of the computer for days, but check it in several approaches. For example: Restoration of 100 failure sectors may require several days of continuous HDDR operation.

Victoria.

One of the most popular methods among users is to restore a hard disk using Victoria. This program, unlike HDDR, applies to a free license.

Victoria can work in both Windows and DOS mode, allowing you to view the SMART table, scan the surface of the disk for failed sectors, restore them, as well as carry out low-level formatting.

Preparation

Before you start checking the disk, you must configure the hard drive controller in the BIOS. On the Main tab, the "SATA MODE" parameter set the "IDE". After that, you can run using the Victoria boot flash drive.

After downloading from the drive in the DOS mode, select the IDE channel with which you are going to work. To do this, press the P key and check the "EXT. PCI ATA / SATA "(if the disk is connected via the SATA interface). For IDE disks, select the appropriate port.

A list of channels will appear on the screen, which will be numbered in order. To select your hard drive, press the digit that corresponds to its number, and then press ENTER.

You can identify errors and without scanning is enough to see the SMART table of the hard drive. You can call it using the F9 key. In the table, pay attention to two points:

The more broken sectors, the less chances that the disk will be able to restore. However, you can try to return to it working capacity by running the scanning process.

To call the disk scan menu, press the F4 key. Select "BB: ERASE 256 SECT" using the keyboard arrows and press ENTER. The scanning process will be launched, which will be quite long. You can interrupt the scan using the ESC key.

If the sector is detected, the program will try to erase it. If it is physically working, then the attempt will be successful and you get rid of the broken parts of the disk. Information will be deleted at the same time, however, it is not necessary to worry much about this - to pull it out anyway it would be problematic.

If the sector is damaged at the physical level, then an attempt to erase it will be unsuccessful. An error message appears on the screen. However, this does not mean that you need to stop the disk scan.

If you cannot restore sectors, try transfer them to the backup area. Press the F4 key and select the arrows item "BB: Classic Remap". The scan process will start again. This time the broken sectors will not be recovered, but transferred to the backup area.

After the disc scanning is completed (subject to the restoration of the sectors), it is desirable to check the file system using the chkdsk utility.
