Bad sectors on the hard drive. How to remove bad sectors on a hard drive. Disk management of my computer

The technique also suffers from diseases, wear and tear during operation and force majeure in the form of a cup of tea overturned on the keyboard, and then a person comes to the rescue. Of course, it is impossible to foresee everything, but to optimize software and the owner is still able to protect the computer from viruses. How do I use the CrystalDiskInfo program used to protect my computer? We will talk about this in the article.

general information

CrystalDiskInfo for Windows, distributed free of charge, is one of the most well-known health monitoring tools hard drives... The software is used by both beginners and experienced professionals. This is because CrystalDiskInfo is not only a convenient, but also a visual tool with many options. An inexperienced user can use it to monitor the state hard disk, and the programmer will find the disk scores for a variety of parameters.

The software determines the technical condition of the computer hard drives, displays their temperature on the screen, and specifies the S.M.A.R.T. level. All data are presented in an understandable and visual form, the criteria that determine the general condition of the disk (good - green, satisfactory - yellow, poor - red, unknown - gray) are highlighted in colors. But how do you use CrystalDiskInfo?

Program functions

CrystalDiskInfo detects signs that can affect equipment failure so you can take action ahead of time. CrystalDiskInfo regularly monitors and checks various information media, including hard drives and solid state drives. This utility scans a large number of disk indicators using S.M.A.R.T. technology, analyzes them and displays them on the screen in an understandable way.

Where and how to download?

How do I use CrystalDiskInfo? Where to download and how to install the software on your computer? The program can be freely downloaded from the official website of the company that developed the tool for monitoring the status of hard drives, completely free of charge. Developers also detail and simple language explain how to use CrystalDiskInfo.

The software can be downloaded in several languages, including the Russian version. On the download page, you can choose one of several program options: there is a regular version and a Shizuku Edition. The Shizuku Edition offers several visual themes to choose from.

You can also download to your computer source tool, but this is only suitable for advanced users who are interested in the program from a technical or professional point of view. Both the standard program and the Shizuku Edition are downloaded from the archive.

Program installation

How do I use CrystalDiskInfo? The portable version can be used immediately after the download is complete: you just need to unpack the zip-archive materials into any folder and open the required file (DiskInfo32.exe for a 32-bit operating system or DiskInfo64.exe for a 64-bit one, respectively). If you used an exe-installer, carry out the installation according to the simple instructions of the program, which are listed in the ReadMe.

S.M.A.R.T.

The status check is carried out using a special technology Self-Monitoring, Analysis and Reporting Technology, which in Russian means "technology of self-monitoring, analysis and reporting." Hence, as the name suggests, the role of the S.M.A.R.T. - research of the state of the disk and transmission of information about those malfunctions that the user may encounter in the near future.

The system checks a large number of different signs and, combining the indicators, makes an overall assessment of the health of the hard disk. The owner of a computer does not have to understand all the variables, since S.M.A.R.T. independently analyzes the data and broadcasts it to the screen in an understandable way.

Programming interface

After installing and launching the program, it will open Workspace... The tool interface is intuitive. The working window of the program can be conditionally divided into five areas:

Disc selection area. This location displays all media that the software has detected on the device. Information about their general position and some characteristics are displayed.
Leading characteristics of the disc. Here you can see some parameters of the disk: firmware version, interface version, material transfer level, as well as the speed of rotation (only for HDD), the number of starts and the joint operating time.
A compressed summary of the status of the disk. In this area, the position will be characterized by one of the colors - from blue to gray. In addition, in this part of the program window you can see the temperature of the disk. The operating temperature will also appear on a blue background, and the dangerous one on a red one. When the state is constantly being parsed by CrystalDiskInfo. The alarm is announced immediately. A high temperature will most likely lead to severe damage to the hard drive, therefore, in such cases, you need to understand and eliminate the cause of overheating as soon as possible. Experienced programmers can independently disassemble the equipment and thoroughly clean the ventilation structures from dust, while a beginner is better off contacting a specialized center.
The largest part of the program window is S.M.A.R.T. Here you can find information about the parameters that are checked using this technology.
Indicators of the level of parameters S.M.A.R.T. They are characterized by the same colors as the general position or temperature. By moving the mouse cursor, you can see a tooltip with detailed information about the reasons for the loss of performance.

Checking the state of technology

If the CrystalDiskInfo program is already running, how to use it? Anxiety does not build up enough experienced users... However, for professionals, the program is a wide field for study.

For the most effective use of CrystalDiskInfo, you need to constantly maintain the reassigned sectors on the hard disk by disinfecting CrystalDiskInfo. It is very simple to implement this: you need to activate "Service - Autostart", and the program will detect the automatic loading of the element when the operating system is turned on, and "Service - Start the agent" will put the program icons, which will make it possible to view the temperature of the disk in real time at any time.

In addition, you can configure immediate alerts about a dangerous disk state. The tool works with sound alerts, messages on e-mail and can also analyze the event log.

Reassigned sectors

Finally, the CrystalDiskInfo program is installed and running. "Reassigned sectors" - such an inscription appeared on the monitor screen. What it is? Bad sectors that were found on the surface of the disk are called remapped. Information from such areas is copied to the backup area. They have not yet become damaged, but a large number of them slow down the functioning of the hard drive. The unexpected appearance of a significant number of such sectors may indicate problems with the security of the drive.

Damage indicates that the hard drive is gradually losing its resource - this is not yet critical, but it is still better to copy the information to external storage. HDD obviously will work for a limited time - maybe a month, maybe even a year. In any case, you need to transfer the data to an external medium.

Unstable sectors

We continue to learn how to use CrystalDiskInfo. Are there a significant number of unstable sectors? Hard drives HDDs are safe and durable mechanisms, but they also break. Over time, they fail. Damaged areas appear on the disc. They are usually detected when examining the disk with programs like CrystalDiskInfo.

Most often they occur precisely because of failures or unexpected shutdown of the computer. If the controller has some difficulties while processing a sector, it marks it as unstable. If the errors are repeated, the controller will remap the sector. The appearance of such problems is not yet a reason for repair, but you still need to monitor the disk. Although there were cases when information on disks was read without difficulty with 1000 or more unstable sectors.

However, if the problems nevertheless intensify, you need to do backup received files. If CrystalDiskInfo indicates the presence of not just unstable sectors, but serious damage, then, of course, you need to take action.

As a result, it can be noted that this utility is very necessary for almost all computer owners, since the performance of the device as a whole depends on the "health" of the hard disk. And this is not yet a question of the safety of information.

Disk Revival is a program for locking unstable sectors. The idea of the program is very simple - files are written to these damaged areas. Then you can use hdd. Since unstable clusters are locked, the user's documents will only be written to good space. Therefore, the speed of working with a disk (ssd, flash) will increase.

Is it possible to fix or remove them?

Such areas can only be blocked; it is impossible to fix or remove them. This is due to the fact that these areas are physically damaged (or close to damage). In any case, these are physical changes to the surface of the hdd. But such a blocking temporarily solves the problem, provided that it is possible to write the blocking files.

Have this method there are restrictions. The lock will be reset if:

do formatting
delete folder with lock files
defragment a disk standard Windows utility. Defragmentation by others is possible if it allows you to add a folder with block files to the exclusion

For example, let's take a real hard disk with bad sectors. Friends, minimum unit information on the hard disk is a sector, the amount of user data is 512 bytes, if the information in the sector cannot be read, then the sector is unreadable or, in other words, faulty. All operating system freezes occur when reading information from such a sector. This WDC WD5000AAKS-00A7B2 hard drive (500 GB) is really faulty.

The operating system on it constantly freezes and periodically at boot it starts checking the hard disk for errors. The last straw for the owner of the hard drive was that it was not possible to copy important data to another disk, and even reinstalling the operating system ended with another freeze on unpacking Windows files, replacement installation disk it gave nothing with the operating system, the hang was repeated at another stage of the installation. It was then that the question arose of what to do with this hard drive, because one of the partitions contained important data and had to be copied.

Victoria launch

Launching the Victoria program as administrator... We agree with all warnings about working in a 64-bit system.

We select the initial tab Standard. If we have several hard drives, in the right part of the window, select the required hard drive with the left mouse, in our case WDC WD5000AAKS-00A7B2

and go to the SMART tab,

press the Get SMART button, the GOOD message will light up to the right of the button and S.M.A.R.T. will open. our chosen hard drive.

5 Reallocated Sector Count - (remap), denoting the number of reassigned sectors, this means spare sectors on the spare tracks end and soon there will be nothing to reassign bad sectors.

Go to the Tests tab.

Hard disk surface test in Victoria program

In the right part of the program window, check the Ignor item and the read item, then click Start. This will run a simple hard disk surface test without correcting any errors. This test will not bring any good or bad effects on your hard drive, but when the test is over, we will know what state our hard drive is in.

It starts scanning the surface of the hard disk and after a while bad sectors are found. After 40 minutes, Victoria gives us the following result:

The victim's hard drive WDC WD5000AAKS-00A7B2 (500 GB) was divided into two partitions: drive D: with an operating system of 120 GB and drive E: with data of 345 GB.

Before working with the Victoria program, we will secure ourselves and make a full image of the disk E partition: the volume is 345 GB and we will extract the data from the image. We will make the image in another DMDE program and place it on another physical disk SAMSUNG HD403LJ (400 GB), I will show you how to do it.

Disk management of my computer

Important data is located on the New volume (E :) with 347 GB of WDC WD5000AAKS hard drive (total 500 GB), so we will create an image of the partition (E :). Create a sector-by-sector image of the (E :) partition on a SAMSUNG HD403LJ hard disk (400 GB), there is only one partition on it without data New volume(F :). The third physical disk in the system is an SSD (120 GB) drive (C :), which contains our operating operating system Windows system 8.1, which we are now in.

Creating a sector-by-sector image of the entire hard disk or the desired partition in the DMDE program

This program is familiar to us from the articles in which we are on the hard drive, as well. Also DMDE is a very good tool for making sector-by-sector copies of a failed hard disk. We go to the website of the DMDE program:

And download the program, click the GUI for Windows.

DMDE is downloaded in the archive, unzip it and run the file dmde.exe.

Then we select the language Russian.

We accept the terms License Agreement... In the initial window of the program, we need to select either a Physical device (that is, a completely hard disk) or a data partition to create an image.

We only need the volume (E :), so we mark our WDC WD5000AAKS hard drive with the left mouse, then we mark the item Logical drives

and the (E :) section, then click OK.

Menu. Create Image / Clone ...

Place for recording, click Disk.

New volume (F :) and OK. It is necessary that the partition on which the sector-by-sector image of a faulty hard disk (or a partition with unreadable data) will be created should be at least as large as this disk.

All data will be deleted on the new volume (F :), agree Yes.

The creation of a sector-by-sector copy of the partition (E :) of a sick WDC WD5000AAKS hard disk begins on a new volume (F :) of another healthy SAMSUNG HD403LJ hard disk, which lasts 6 hours (the image is removed from especially "bad" screws for several days) and hangs tightly at 83 percent, after waiting a couple of hours, I clicked on the Abort button! Friends, if we interrupt the creation of the image of the sector-by-sector section at the very end (after all, 83%), then we will have two options, as Suvorov used to say - "either the chest is in crosses, or the head is in the bushes."

After interrupting the operation, we go to the New volume (F :) and see if there is any data on it and ... they are, all the main things that we needed the DMDE program managed to transfer to the disk (F :), almost all the data read without errors. This means that our case is not complicated and the beds are mostly software-based.

But in some cases, not everything will be so rosy, and when you try to enter a section with a sector-by-sector copy, this error will be waiting for us: Access to F: \ is denied. The file or folder is damaged. Reading is impossible.

Access to F: \ is denied. The file system is not recognized. Make sure all required system drivers are loaded and the volume is not damaged.

But even in this case, we will not give up and will do so.

What to do if creating a sector-by-sector image goes wrong

Friends, the process of creating a sector-by-sector copy does not always end successfully even after several hours, but if you stop creating a sector-by-sector copy, the data in it may be unreadable.

Or, in the process of creating a sector-by-sector copy, such an error will appear " The request was not completed due to an I / O error on the device"(see screenshot below) indicating that DMDE could not read the information in the bad sector (the sector number is indicated in the error) in this case, click

"Retry", there will be a repeated attempt to read information from this sector and it may end in success. If this error with the same sector appears again, then press

"Ignore" and the creation of the sector-by-sector image will continue, but we will lose information in this sector and as a result, a single file will not open in a sector-by-sector copy. If the error "The request was not completed due to an I / O error on the device" appears too often, you can select

"Ignore everything" and similar errors will be skipped, but you can press the button

"Parameters" and adjust DMDE accordingly for such a difficult case. Click the Options button in this window.

"Reverse", sometimes it brings results.

And press again "Parameters".

In this window, check the box "- Is always"... If you select this option, the operation will continue even

in case of an error related to the lack of readiness of the device. If this option is not checked, then on some "bad" hard drives a warning will be displayed with the expected response of the user, that is, the image will not be created on the machine.

Auto retry count on CRC error - 0

Fill bad sectors (hex)

Then OK and OK, the creation of a sector-by-sector image begins.

Left-click to enlarge image

This option of settings also proved to be workable.

Skip I / O Errors - Always

Don't wait if your device isn't ready - Is always

Retry count on CRC error - 0

The number of auto retries if the sector is not found - 0

In general, I would advise you to study the manual for the DMDE program http://dmde.ru/manual.html or http://dmde.ru/docs/DMDE-manual-ru.pdf, you can also wait for our article on creating a sector-by-sector image of a faulty hard drive with various programs, in which we will even consider creating a bootable USB flash drive with the DMDE program.

If DMDE does not help you, then you can try other programs, for example. Of course, there are still ways with which you can make a sector-by-sector image of a bad screw, for example, boot from some Linux-based operating system, for example Ubuntu, but I will not describe the process itself and I’d better write a separate article. You can also run the safecopy utility under Linux.
What to do if, nevertheless, you cannot make a sector-by-sector copy of the hard disk, you choose. You can contact a good and proven service for data recovery and a sector-by-sector copy from your hard disk will be removed using special expensive equipment by specialists, for example, using the same PC-3000 complex. If you do not feel sorry for your data, then you can take a chance and run algorithms in the Victoria program that rid the surface of your hard disk of bad sectors (bad blocks), as described below, the hard disk after this operation can come back to life.
Important: Kazan(the developer of the program Victoria) promises that the most innovative algorithm for hiding bad blocks BB = Advanced REMAP is NOT destructive for data, but in some cases it can be destructive for your files, since even the most advanced algorithm of Victoria Advanced REMAP hiding defects (remap), this is for any change in the translation of the screw, which means the loss of user data (details below. I want to say that sometimes it happened that Victoria will cure the hard disk of bad drives and you will even be able to copy the information from such a hard drive, but unfortunately not all information is readable ...

So, in our case, the DMDE program managed to make a sector-by-sector copy of a sick hard disk, namely a new volume (E :), although in some places DMDE hung a little, but everything ended successfully. A sector-by-sector copy of the new volume (E :) is exact copy and is located on volume (F :). All available data is successfully read and copied.

The main task has been solved and user data has been saved, now we proceed to the procedure for treating the hard drive.

How to get rid of bad sectors (bad blocks) using the Victoria program

Friends, now let's imagine that we did not manage to make a sector-by-sector image of a hard disk with bad blocks and we didn’t come up with anything else and decided to rid our hard drive of bad blocks in the Victoria program, in the hope that after hiding the bad sectors we would be able to read and copy the information to your hard drive.

Note: it is difficult to get rid of the screw from bad blocks in a running Windows, especially if, for example, you have a laptop with one hard drive and an operating system is installed on the same hard drive and you want to cure the same operating system from bad blocks. In such cases, create bootable USB drive with Victoria, boot a laptop from her and get rid of bad sectors. I propose to create a bootable USB flash drive in the next article, but now we will learn how to do this right in the working operating system, I'll show you everything.

Remap

In the main window of Victoria, check the Remap item, which denotes the algorithm for reassigning bad blocks to sectors from backup tracks during scanning. The test is in Read mode, that is, from beginning to end and press the Start button.

While the scan is in progress, let's talk about this.

1. What happens with this Remap algorithm? An attempt is made (several times) to forcibly write information to the bad sector of the hard disk if the attempt is successful, then the sector becomes healthy and is removed from the list of bad blocks (no remap occurs). If the write attempt is unsuccessful, then the diseased sector is reassigned to the healthy sector with a reserved track of the hard drive specially designed for such cases.

2. Remap is the reassignment (replacement) of a sick sector, assigning its LBA number to another physically healthy sector from the backup track. Information from the sector (at the time of reassignment) hangs in the RAM of the screw, and as soon as the sector is reassigned, it is written back.

Remap is basically not destructive for information, if your data is lost, then only in one bad sector, but you must admit that the data in the bad block was already unreadable. In the second case, the data will simply be transferred to the sector from the backup track.

Result. As I said, it is difficult to fix anything in a running Windows and Victoria cannot perform a remap. After 20 minutes, the same result, 13 bad blocks, and you and I will have to make a bootable USB flash drive with Victoria and work in DOS.

How to scan a specific area on your hard drive in Victoria

If you know the exact addresses of bad sectors, you can set the exact scan parameters in the Victoria program. For example, we know that our bad blocks start from sector 770,000,000, then in the Start LBA item: set this number here and the Victoria program will start scanning and fixing the surface of the hard disk from sector 770,000,000, also if you set the one you need number in End LBA: then Victoria will end the scan on the sector you need.

Erase Algorithm

Friends, you may ask me, what will happen if you apply the Erase test or still have Write?

Erase on unreadable sector detectionforcibly overwrites the entire block of 256 sectors with zeros(be careful, in some cases your data on your hard drive will be deleted).

Most often, you come across software (software) bads, which are removed most quickly by zeroing - the Erase algorithm, and even if writing to the zeros sector is unsuccessful, a Remap may well occur, since the hard drive's firmware may consider such a sector to be bad. If Erase does not help, then you can choose Remap, but as we know, the chances of Remap being produced on a running Windows are slim.
In some cases, soft (software) bads can be removed even by simple formatting using Windows itself. The whole difference between the existing bad blocks: physical and software, read our article. I will explain in a nutshell that physical bads (a physically destroyed sector) cannot be restored (only remap, reassignment is possible), and logical (software, sector logic errors) can be restored.
Friends, we can, but then our article will be even longer, we will also do this in the next article.

I do not want to experiment on our WDC WD5000AAKS hard drive, because in the next article I plan to cure it of bad blocks in DOS mode using a bootable USB flash drive with the Victoria program and still return the hard drive with intact data to the owner of the hard drive cured of bad blocks.

I'll just show you on another hard drive how to run this test on a running Windows.

In the main window of Victoria, select our hard drive and go to the Tests tab, check the Erase item (be careful, in some cases your data on the hard drive will be deleted)- when an unreadable sector is detected, it forcibly overwrites the entire block of 256 sectors with zeros, of course, information is completely lost in the whole block of sectors, but if overwriting occurs, the block returns to work (becomes healthy).

The test is in Read mode, that is, from beginning to end and press Start.

Often, when "zeroing" in a running Windows, the following errors will appear:

Block (bad sector number) try Erase 256 sectors... Failed to overwrite block of sectors.

Algorithm Write

The Write mode does not look for any bad sectors, but simply immediately overwrites all the information on the hard disk by filling all sectors with zeros, this is in the jargon of the repairmen "Writing across the entire clearing", this algorithm is able to cure the hard disk of bad read latency, but n After such a test, it will be impossible to restore data on the hard disk, so copy all important files to the portable hard disk beforehand.

Note: Friends, we have written an article about the Write algorithm, if interested, then get acquainted: -.

Moving on to the next article!

For those who are poorly familiar with a computer and do not know what DOS is, it is better not to repeat everything that will be described in this article, since here we will talk about how to restore damaged HDD sectors.

And so you found out that you constantly have a disk check at boot, or the hard drive began to slow down a lot. You are talking about scanning with some utility in read mode (read) or any program from this article. Thus, you made sure that you have slow sectors that respond longer than 500 ms, or BAD sectors, then this article is for you.

How to fix broken sectors

If your disk periodically disappears or does not see each other at all, then this is already a problem most likely with the controller, cable (loop) or power supply, but we will talk about BED sectors and very slowly read cells, in general software errors hard drive.

So you found (HDD checker program) that you have slow sectors on your hard disk (usually red or brown). The decision to apply low-level formatting (Erase), we do it with the program MHDD and just, forget the programs that work from under windows, they will not help you like HDDscan and Victoria.

Attention!!! All operations described below can lead to partial or complete removal information on your hard disk drive (HDD).

So we boot from the boot disk where this MHDD program is, these are collections of STEA Live, Hiren boot cd or do it yourself boot disk or a USB flash drive.

Stage 1. Getting rid of slow (red) sectors

Launch MHDD, type the command Erase, the list of all commands can be viewed by the F1 command, the program will ask you to specify the scan range, do not change anything, press Enter by default, wait. If the red sectors remain, then you will have to run the command Erase waits

Stage 2. Getting rid of bad sectors

We launch MHDD, type the Remap command, and the program will automatically scan the hard disk and replace bad sectors with spare ones, I do not recommend running this program with a large number of red and bad sectors in the hard disk partitions.

You can also clean the HDD from bad sectors manually, while not the entire hard drive, but partially along the range of addresses.

We execute the command SCAN, as soon as the BAD sector appears, we remember its number, stop the ESC process, run the command Erase and we indicate the range in this case, if there is one bad sector, then its number and the next, that is, we add one, then we run the command again Scan and we look at the appearance of new broken sectors, we repeat the procedure.

The video shows the whole process well:

If scanning takes a very long time for you, then no program will help you. And you will have to buy already new hard disk.

P.S .: I am attaching a link to a video showing the operation of the MHDD program for general information

18 comments to write How to recover damaged bad (BAD) sectors of HDD

Well, you give a hint. booted from MHDD wrote how you have it in the first paragraph of Erase and erased all Windows did not help even the restoration through the archive right now on new Windows I put it.

Dear yura200, if you would carefully read the article, then it says that Erase- this is low-level formatting, well, I hope the word formatting, do you understand what it does?)

So what for to write the first point, write erase well that after installing Windows it could roll back right now all the way. The most interesting thing is that I wanted to start this business from the D disk and there are family vidyashka pictures that I would have grabbed with grief, but it's good that MHDD did not see the D disk and only the C disk was formatted. I push here so that others do not rub the whole screw. And where in what place in the text do you say that Erase is formatting? When I used Mhdd, I used erase when grouting block troubles. Correct the text.

yura200, I am very sorry that you have experienced such difficulties, but all that you do is your personal desire. In the text, the third paragraph:

So you found (HDD checker program) that you have slow sectors on your hard disk (usually red or brown). Decision to apply low-level formatting (Erase)

P.S .: And for interest you can look at the translation, it also says a lot erase- erase, delete (from memory).

Good afternoon.

Can you tell me how to make the program work on a laptop? Neither MHDD nor Victoria can see my hard drive.

Danila Are you sure you have an HDD in your laptop? and not SSD, because with the second disks, the MHDD and Victoria programs do not work.

Dear! If you see orange or red on your disk during the test, or even an X in a square, then do not torment him, he is finished. These people are just trying to somehow support them with a stroke, and then you see what they then become, and the pieces of iron, after you took off the pictures, one way to a well-deserved rest. And don't listen to or read the recovery bullshit.

Indeed, on the ASUS X552EA laptop, the MHDD program does not see a 500 GB WD HDD (not an SSD, and not a hybrid, normal one).

I played with the BIOS - this way and that ... alas, the MHDD program opens from the bootable USB flash drive, but does not see the disk, no matter how hard I tried.

It is necessary to set the HDD operation mode SATA Standart IDE INSTEAD OF SATA AHCI

I want to check and fix the bad sectors in dos (I checked it in winows before with Victoria) But I can't switch from AHCI to IDE in BIOS, there is nothing similar. Hp laptop (they wrote that they removed this function) How can you help?

Put this hard drive in the system unit and run it there and, if necessary, configure the BIOS.

Respect and respect to the author! The user does not have the funds for a new hard drive, and the system engineer is vital ..., so I found along the above trajectory that, in addition to the first 42 gigs of crosses, there are two more thirds of the working space .., and the person is grateful!

Thanks a lot for the article!

It was necessary to restore the functionality of the old disk. I scanned its state with the MHDD program (found it on an old CD-reanimator), found several dozen "red" sectors, but did not know that the ERASE command was exactly what I needed. I thought it was a simple erasure of information.

Now, after processing the disk with ERASE, I scanned it again. Result - not a single BED!

The question is if there are bads in the first 4 gigs and the last 4 gigs, and there are 2047 of them, is there any reason to strain to recover?

Andrey unless you need to pop the leftover data from the hard drive, but I wouldn't use such a drive in the future.

Is 653 bads really bad? Erase won't help?

Max yes this is really bad

Hello bortvlad. Is it worth bothering with the treatment of bad? Windows so monitors and corrects cells as much as it can. And it will not write down the info in the bed. The loss of speed is negligible. And replacing cells from the spare area changes the desired table, which, in my opinion, will only speed up the death of the HDD. If it's really a very tight low-level formatting and use the disk for archiving movies, games .... What can you say about this software: Low Lewel Format Tool?

Over time, bad sectors appear on any HDD, which are inaccessible for reading. When the number of bad blocks exceeds all permissible limits, the hard disk refuses to work. However, under certain conditions, the hard drive can be cured using special software.

What are bad blocks?

An HDD (hard disk) is a series of magnetic disks with a head that records and reads information above them. The drive surface is divided into tracks and sectors (the smallest division unit). If information is not read from a certain sector, then this is: bad, bad, broken, or just a bad block.

Recovering bad sectors is not an easy task, but doable. If there are few bad blocks on the HDD, you can cure the disk, while simultaneously extending its life.

The very presence of bad sectors is a bad sign, therefore, even after repairs, you cannot use the HDD for a long time - it can fail at any time.

Working with VictoriaHDD

VictoriaHDD is one of the most well-known hard disk treatment programs. It is distributed under a free license and allows you to fix bad blocks in DOS mode. However, working with it requires some preparation.

Creating a bootable USB flash drive and configuring the BIOS

Download the VictoriaHDD utility ISO and write it to a USB flash drive using WinSetupFromUSB.

Open WinSetupFromUSB and select the connected USB flash drive.
Check "Auto format", choose "FAT32".
Specify LinuxISO / otherGrub system and click the button on the right. Show the path to the downloaded ISO image through the explorer, click "Go" to start recording.
After creating the Victoria bootable media, you need to restart your computer and open the BIOS. In the "Main" section there is an item "SATA Mode" - for it you need to set the value "IDE", because in the "AHCI Mode" Victoria does not recognize the connected disk. Press F10 to exit BIOS and save changes.

After completing all the preparatory steps, restart your computer again. At startup, start pressing F11 to bring up the boot menu. Select the Victoria bootable flash drive to run the program in DOS mode.

Recovery and subsequent verification

To restore, do the following operations:

After starting, press "P" ( english layout) to bring up the Port Selection menu. If the hard drive is connected via the SATA interface, select the “Ext. PCI ATA / SATA ". For hard drives connected via IDE, you need to select the appropriate port.
A list of channels appears, each with a number. See what number your disk is designated and enter it in the field below.
Press F9 to open the SMART table. Study two points: "Reallocated sector count" and "Current pending sectors". The first line contains the sectors transferred to the reserve zone; in the second - places from which information is not read (bad blocks). If there are few bad sectors, try to repair them.
Press F4 and start the "BB: Erase 256 sect" mode. If during the analysis the program finds a bad block, it will try to fix it. If the sector is not physically damaged, then Victoria will heal it. Information from this place will be erased (therefore, it is advisable to transfer all required files in advance on a different medium), but the number of bad blocks will decrease.
If the sectors cannot be restored, transfer them to the backup area. Press F4 again and start the "BB: Classic REMAP" mode. Look at the SMART table after the scan is complete - the number of bad blocks should decrease.

After running Victoria HDD, it is advisable to check the disk:

These measures will help you to eliminate bad discs, which will ultimately lead to an increase in the duration of the hard drive.

Using HDD Regenerator

If Victoria seemed difficult, try performing disk recovery and fixing the so-called bad blocks using the program HDD Regenerator... The peculiarity of this utility is that it has access to the software and hardware of the HDD. HDD Regenerator really tries to cure bad sectors, while most programs prohibit access to bad blocks, as a result of which the volume of the hard drive decreases.

To fix this problem, start Task Manager (Ctrl + Shift + Esc) and close all applications. Go to the Processes tab and quit all processes started by the user. Click Retry to make the program try to access the disk partitions.

If the warning window reappears, restart your computer and start the system in safe mode... You can ignore the warning by clicking "Cancel" rather than "Retry", but then HDD Regenerator will work with some limitations.

A window will open resembling command line... In it you will see 4 options for the program:

Checking and restoring bad blocks.
Checking without recovery, showing information about bad blocks.
Regeneration of bad sectors at a specific location.
Statistics output.

First select operating mode # 2. The hard drive will be checked for bad. The next screen will appear, where you are asked to specify the interval in which to look for bads. Better to start testing from the beginning, so leave the value at "0".

After starting the disk scan, a progress bar will appear. You will have to wait a long time; sometimes the system will freeze - this indicates that the program has detected bad sectors and is now determining the extent of their damage.

When the hard disk surface analysis is complete, a report appears. Examine the points “bad sectors founded” and “bad sectors recovered”. These lines indicate the number of found and recovered bads. If the line “bad sectors founded” contains a lot of bad sectors, then you will hardly be able to fix bad sectors, but you can try.

Recovery of bad blocks in HDD Regenerator

Connect a USB flash drive and run HDD program Regenerator. Select the "Bootable flash drive" mode. Highlight the connected drive and click "OK". All information will be erased from the flash drive. Instead, files will be written to enable DOS mode to start. Further:

Reboot your computer.
When the system starts, start pressing the F11 key until the drive selection window appears.
Select the removable disk that contains the HDD Regenerator files.

The program will run in DOS - this mode is better suited for curing bad sectors. The window that you already saw when working in Windows will appear. Select check and restore bad blocks (operating mode no. 1).
