What to do if the hard drive cannot be formatted. Low-level formatting of a hard drive: what, why and how. Reasons for the error

In addition to the fact that information can be stored on a computer’s hard drive or in some partition that is a virtual volume, removable media is often used. However, sometimes when preparing a device for transferring information to it, it may be necessary to format it. And here a problem may arise due to the fact that Windows cannot complete formatting. Solving it is not that difficult.

What is formatting

From the point of view of computer science, formatting is a software process of marking the area in which data is stored. To put it simply, this is the conditional creation of a table indicating the clear location of sectors and clusters.

A sector is a minimum cell with a size of 512 bytes, and such cells can be combined into clusters (several homogeneous sectors). As a rule, to unify data storage, most operating systems use clusters with a size of 512 bytes and larger. For example, sectors can be clustered up to a size of 4096 bytes (4 sectors).

So the formatting process creates not only a numbered markup work area, but also gives a clear indication of where (at what address) this or that sector or cluster is located. This is best demonstrated using the example of a chessboard or the game “Battleship”. illustrates an example of the arrangement of sectors (one figure on one cell).

"Battleship" in this regard gives an idea of ​​how sectors are combined into clusters (2, 3 and 4 deck ships).

The same is true with data that takes up some space in the system. You can always accurately determine not even one, but several addresses of one object. This approach allows itself or the programs that are installed in it to quickly find files at predetermined coordinates (addresses).

Formatting Methods

The main methods in this process can be called quick formatting and full formatting.

Quick formatting only clears the table of contents, that is, it simply deletes files and folders.

Full formatting not only completely deletes information, but also creates a new file system, which is required quite often. But here the problem may arise that Windows cannot complete the formatting.

Problems formatting removable media

As for removable media, most often the problem here is that the process of copying information to it was not completed correctly or was forcibly stopped altogether. This used to be very often observed with outdated floppy disks.

In some cases, the problem may be due to physical damage to the surface of a removable storage device, be it a regular flash drive or a USB hard drive. And it should be noted that standard methods do not always help. But more on that later.

Why Windows cannot complete formatting the hard drive partition

Quite often, problems of this kind arise both with formatting hard drive partitions and with formatting the entire hard drive.

Again, the problem may be file system failures or mechanical damage to the surface. However, although formatting may not complete, you can use a few basic methods to resolve the issue without resorting to third-party programs.

Troubleshooting using Windows

If the user receives a system message that Windows cannot complete formatting, do not panic. To begin with, you can use the standard method by right-clicking on the media in the same Explorer and selecting the “Format…” command. This can also be done using the command line (in the main menu, the “Run” command) by entering the format h: command in the line, where h is a removable drive. In the case of formatting, say, the “D” partition, the drive letter (format d:) is simply changed.

Sometimes this does not help, and again a message appears that Windows cannot complete formatting. In this case, you can boot the computer in safe mode, and then issue the command specified above.

In some cases, if formatting cannot be completed, you can use Disk Administration options. This command is called very simply: using the main menu or command line, where the discmgmt command is entered. In the window that appears, you just need to select the desired disk and, after right-clicking, select the same “Format...” command.

Windows 7 formats according to the usual algorithm. But the problem may be due to errors on the disk. Actually, formatting Windows 8 has the same approach. Now you need to call the disk check program. This can be done in the same Explorer by right-clicking and calling up the “Properties” menu, where on the “Maintenance” tab there will be a button to start the scan. Here you can choose a regular scan, a scan with automatic correction of file system errors, and a full scan with a check of the hard disk surface.

You can enter chkdsk c: /f at the command line (it will be done automatically. Sometimes you may need to check the entire file system. To do this, use the command chkntfs /x c: (for drive “C”). For other drives, simply change the letter.

Only after a complete check (sometimes even checking the disk surface) can you start reformatting. As a rule, after such checks (especially if the last command is used for the entire NTFS file system), no problems will arise for any user.

Third party programs

As for using third-party programs to format drives, for example, for USB drives that for some reason are not formatted or show zero capacity, the best option would be to use utilities like D-Soft Flash Doctor, EzRecover, USB Repair Tool, etc. .d. For hard drives (hard drives) or their partitions, you can use software products like Acronis Disc Director Suite or something similar.

In any case, it is impossible to say that any program for formatting Windows 7 or for any other version of the operating system is the best. Each of them has its own unique features and functional set.

When installing the operating system, as well as when changing files or redistributing space between partitions, it is necessary to format the hard drive. This is a fairly common operation performed by PC users. If you haven’t done anything like this before, then let’s look at the theoretical part of the question.

What is the formatting process?

Marking areas for storing information, in which some of it is deleted, is called formatting. It creates a system for accessing stored information.

Typically done for:

  • changing one file system to another;
  • deleting files from your hard drive.

At the moment there are a large number of different file systems. They are used on various equipment, including not only computers, but also mobile devices. The latest versions of Windows use the NTFS file system.

Video: How to format a hard drive

Why format your hard drive?

Formatting is performed to delete files from the hard drive, as well as to change one file system to another.

In most cases they resort to it:

  • before installing a new operating system;
  • to create a Windows installation image, for example, on a flash drive;
  • due to the need to clear the disk of files if they are not needed.

Formatting with Windows tools

Despite the large number of various programs for working with a hard drive, the Windows operating system has its own set of utilities.

Let's look at the process of formatting disks using Windows:

  1. select the disk that needs to be formatted;
  2. press the right mouse button;
  3. select Format;
  4. in the window that appears, select the file system, cluster size, and formatting method;
  5. It is recommended to set NTFS as a file system, and leave the cluster size at the default – 4096;
  6. After setting the necessary parameters, click Start.

Windows also includes a more comprehensive service for working with hard drives.

To open this menu, do the following:

  1. right-click on My Computer;
  2. select Management;
  3. open Disk Management;
  4. In this menu, the user can perform various operations on the hard drive, including formatting.

Formatting via the command line

You can also perform this operation using the command line:

  • Press the key combination Win+R;
  • enter cmd and press Enter;
  • in the command line we write the command format y:, where y is the letter of your drive, maybe, for example, c or d;
  • the system will ask you to confirm the operation by pressing the Y key;
  • after confirmation, the system will begin the formatting process;
  • When finished, this message will appear



Formatting HDD in BIOS

If you need to format a hard drive partition from the BIOS, you will have to tinker a little. Unfortunately, the BIOS does not have tools for formatting a hard drive, so you should use third-party programs to perform these operations.

One of the most common is Acronis Disk Director. To work with it, you need to create bootable media in the operating system with the files of this program. But before you start creating bootable media, you should consider another option - formatting using Windows Installer. This solution is a simpler option compared to Acronis Disk Director.

For this method, you only need a disk or flash drive with a recorded operating system installation package.

To format, you must perform the following steps:


Attention! The drive partition letters may not match. To more accurately determine the required disk, use the wmic logicaldisk get deviceid, volumename, size, description command.

Creating a bootable USB flash drive for Acronis Disk Director

To create a bootable flash drive you will need:


Algorithm of actions:

  1. insert the flash drive;
  2. install and open the program;
  3. in the application, open the Tools section and select Acronis Bootable Media Builder;
  4. click next;
  5. select the Windows PE boot media type;
  6. in the next menu you should mark the necessary components for recording to a flash drive;
  7. After selection, you need to select the media on which to record and click Next. The flash drive should be formatted in FAT 32 format using the Windows utility;
  8. you can also create an image for later burning to a flash device or disk using the Ultra ISO program.

How to format an external hard drive to NTFS

The most convenient formatting method is to perform all actions using standard operating system utilities. This solution does not involve installing additional programs or creating additional boot disks.

If you do not have an operating system installed, then in this case you should use special programs, such as Acronis.

Utilities

In addition to the standard Windows program, there are various utilities used for the same purpose.

The most common options include the following:


What is the best program to format drives in ntfs?

Each program has its own characteristics, but the main direction for all utilities remains the same - working with disks, including creating partitions, forming into other file systems, etc. Therefore, choosing a program is a purely personal question for each user, which depends on his preferences .

Problems and solutions when formatting

How to quickly format a disk without losing data?

Unfortunately this is not possible. All stored information will be deleted. Only part of the data can be recovered.

Which drive is better: external or external?

Formatting external drives is performed in the same way as for a regular hard drive. During this process, all information will be deleted, including windows, after execution the disk will be like new without windows.

Unable to format hard drive

If you did everything according to the instructions, but did not achieve results, do not sound the alarm. This doesn't always mean something bad.

  • format command - cannot be used for a system disk if it is in its environment;
  • if the operating system is located in another partition of the HDD, it cannot be deleted;
  • The settings of the anti-virus program can block access to different partitions of the hard drive;
  • various applications and viruses can block access.

If you have removed the factors described above, but still cannot format your hard drive, you will have to resort to special programs. The most popular tool is HDDscan, which is easy to install and also free.

Algorithm of actions:

  • download the utility;
  • open and install;
  • run as administrator;
  • click on the icon in the form of a sphere located in the center of the interface;
  • select Surface tests;
  • check the box next to Erase;
  • go to the Add test tab;
  • click on Scan;
  • in the lower right corner, write down the error data;
  • set the EraseWAITs option to ON and select Scan again;
  • repeat until the error is cleared.

You can also use Acronis Disk Director. If it is impossible to format a portable hard drive using this program, most likely the hard drive is partially damaged. And the entire procedure can sometimes be performed only from bootable media, that is, not in the operating system.

How to force format a flash drive?

To format flash drives you can use the program HP USB Disk Storage Format Tool.

How to format a write-protected drive?

  • open command line;
  • enter the following commands:
  1. diskpart;
  2. list disk;
  3. select disk Z. Z - flash drive number, execution of the previous command is shown;
  4. attributes disk clear readonly;
  5. clean;
  6. create partition primary;
  7. format fs=ntfs;
  8. exit.

The operating system includes utilities that:

  • provide the necessary set of functions;
  • They have a fairly simple interface that will be easy for novice users to work with.

If, when you try to completely clear the drive of information using the standard method, a message appears stating that Windows cannot complete formatting the disk, try performing the operation using other tools.

Formatting using standard tools

The appearance of this message is a fairly common problem that indicates a failure in the formatting process. If you encounter this situation, try the following steps:

  1. Press Win+R, search for “diskmgmt.msc” to launch Disk Management Manager.
  2. Find the connected media that needs to be formatted in the list of drives.
  3. Right-click the drive and select Format.

Formatting should be started when the volume is marked “Good”. If the volume is marked “Unallocated”, you need to click “Create Partition” in the context menu. In both cases, a wizard will appear to help you complete the necessary actions.

If this method does not help, try formatting in Safe Mode.

To get into safe mode, hold down the Shift key and click on the Restart button in the Start menu.

Once the system starts in safe mode, open a command prompt with administrator rights. Execute a command like “Format E:”, where E is the letter of the drive that should be formatted.

If the error also appears in safe mode, then use third-party software to troubleshoot problems that occur in the operation of the flash drive.

Using programs

First of all, pay attention to two applications:

  • D-Soft Flash Doctor.

These are programs for resuscitating drives that carry out diagnostics and perform low-level formatting, after which all data is deleted from the drive. ExRecover has an extremely simple interface, in which, in fact, there is only one functional button - “Recover”. Clicking on it corrects various errors, including removing problems with formatting and incorrect display of the volume of a removable disk.

D-Soft Flash Doctor offers a little more options: here you can not only restore a flash drive, but also pre-create its image, so that you can then copy the data to another drive.

There are no similar articles.

Digital storage media such as disks and floppy disks have long since fallen out of everyday use due to their low capacity, difficulty of rewriting, and relatively large dimensions. Now they have been replaced by flash drives - small-sized media that can be placed inside the phone and put in any of the existing pockets.


The modern market offers a huge assortment of USB flash drives of a wide variety of colors, sizes, configurations, designs and capacity of the media itself, which varies from one gigabyte or more. Unfortunately, problems happen to them too. One of the cases when a flash drive is not formatted is that Windows cannot complete the formatting: few people know what to do in such a situation. Actually, we will gradually move on to this problem.

So, thanks to the low cost, many users acquire several media at once. Saving information on them is no worse than on disks, but the methods of deleting old and recording new information are much more simple and convenient.


Constant rewriting, deleting old files and adding new ones lead to the need to format the USB drive. But it also happens that when trying to format, the system gives the user information about the impossibility of completing clearing the space on the flash drive.

Why can't I format a flash drive?

There can be a great many reasons for such a reaction from Windows: from problems with USB connectors, a broken flash drive, system errors, to a file located on the media being busy with the system itself. But this is not a reason to say goodbye to your favorite assistant and send it to the landfill: there are a huge number of ways to correct the error and restore the media. As a rule, in 90% of cases it is possible to restore normal operation and return the device to service.

However, even with such inspiring forecasts, do not forget about 10% of cases, because the flash drive could simply exhaust the resource allocated to it, and nothing can be fixed. But to establish this fact, it will be necessary to perform a number of measures to identify the final “diagnosis”.


Before you start formatting, you need to be sure that there is no important data on the device. And if there are still important files left there, then it is important to first restore them using a special program that will initially retrieve the information and then completely clear it of the contents. This issue is covered in more detail in the article “Data Recovery”. Before starting any recovery operations, the USB drive must be inserted into any connector of the computer or laptop.

Disabling antivirus programs

One of the reasons for the inability to format may be anti-virus programs installed to combat malicious files. To check this option, just disable the antivirus and try formatting again. This operation can be carried out in the standard way through “My Computer” by right-clicking on the icon of the corresponding flash drive, where from the drop-down menu select “Format”, and then confirm the operation.


Ideally, the formatting process should start, which will erase the media in the installed format. But if cleaning this way fails and the same window appears, you should try the next method. To implement further methods, all running programs or applications must be closed or terminated so that they do not access files on the flash drive and do not interfere with its cleaning.

Formatting using standard OS tools

For this method, you do not need to search for special utilities on the Internet, but you can simply use the standard Windows software. To do this, first launch the Disk Management menu through the operating system. This launch can be done in two ways.


1) By pressing “Win” + “R” from the keyboard, after which the “Run” command window will appear on the screen. In the line of the pop-up window, enter diskmgmt.msc and confirm the action with the corresponding button on the window or the “Enter” key. This method is supported by any version of Windows.


2) Click the Start button and then select Control Panel. Whatever method is used, in the menu that appears, click on “View: Category” and select “Small Icons”.


The next action is to click on the “Administration” item and then go to the “Computer Management” section.


The window that opens will consist of three areas, on the left of which you will need to select “Disk Management”.


After going to “Disk Management”, all information about connected devices, their size, type, etc. will be displayed. To format a flash drive, you will need to find it in the list, since it will then be impossible to restore data from the media or disk. Right-click on the drive icon and select “Format” from the menu that opens.


If the “Delete volume” function is active in the USB drive menu that opens, then you should first select this action, as it will help distribute space on the disk. After distribution, select the “Create simple volume” column. The Volume Creation Wizard will walk you through the steps at which you will need to confirm what to do next. After creating the volume, the flash drive can be formatted.

How to format a USB drive in safe mode?

First, the safe mode itself starts - the system reboots and “F8” is pressed at startup. After which a menu will appear allowing you to select startup options, where you will enter safe mode. This mechanism may differ in different operating systems.

From safe mode, formatting is done using the command line. But at the same time, you need to make sure that no data from the flash drive is used by programs, for example, not scanned by the same antivirus. The command line is called by the universal method - by pressing “Win” + “R”, after which the “cmd” command is entered into the line and confirmed with the “Enter” key.


The following command “format x:” appears in the command line window, where x must be replaced with the corresponding name of the flash drive under which it is displayed on the computer, and confirmed with the “Enter” key.

Formatting a flash drive using special programs

If the above methods do not give the desired result, then you should seek help from special utilities that have proven themselves to be the best “doctor”, even for seemingly hopeless devices.


A program designed not only for formatting storage media, but also for quickly creating bootable disks. To erase data here, you need to follow the following sequence.


  • Connect the USB drive to your computer or laptop via any connector.
  • Download the HP USB Disk Storage Format Tool and run it as an administrator: otherwise, the utility may simply not start.
  • Wait until the media is detected and appears in the “Device” menu.
  • Select a file system format appropriate for the purpose of the media.
  • Set the media name that will be displayed on the PC.
  • Next, select quick formatting.
  • The process starts with the “Start” button.

Depending on whether the Russian or English version is installed, all commands will be displayed accordingly, but instructions for formatting in any language version are performed in the same sequence as given above.


There are also situations when portable memory cards for mobile devices cannot be formatted for some reason. In these cases, it is necessary to use the SDFormatter program. When launched, it should appear as a normal window.


In the “Drive” column, you need to select the device that will be formatted and press the “Option” button. After which a new window will appear with two columns, in the first of which you need to select “FULL (Erase)”, and in the second set to “ON” to improve the structure of the media and the quality of its further work.


All of the above methods are designed to restore a flash drive, but if they do not help, try taking measures to restore the device with other programs, for example, D-Soft Flash Doctor, EzRecover or JetFlash Recovery Tool.

Specifying Attributes Using the Command Line

As a rule, the above methods and programs are more than enough, but if they turn out to be ineffective, then you can resort to the next method. To complete it, you will need extreme care, since the whole process will take place in several stages.

The universal combination “Win” + “R” opens the command line. As before, go to the “Run” section, then enter the “cmd” command, which is launched by clicking on the button or pressing the “Enter” key. In the window that appears, enter the “diskpart” command and confirm it.


After this, the “list disk” command is installed in a new window, which will display the connected disks. Here you select the media needed for formatting, which is determined by the capacity of the flash drive.


Having found out its number, you need to enter the command “ select disk", in which n is replaced by the number of the media intended for formatting, and press “Enter”.


After this, you need to make changes to the attributes, for which the following command is written: “attributes disk clear readonly”, and launched with the “Enter” key.


Upon completion of the procedure, to finish the work, enter the “exit” command into the command window and run it. Then you need to try standard formatting methods in the operating system.

Conclusion

If this method does not remove the window with the information: “Windows cannot complete formatting,” then you can try to perform all the procedures on another computer or laptop. It is quite possible that the reason for the failure to format was the PC itself or the USB connector. In this case, it is better to check the last option immediately by inserting the flash drive into another connector.

We hope that the methods proposed in our article helped you recover your USB drive and format it as originally intended. If the article was useful, share it with your friends, perhaps it will help save their flash drives from disposal. Thank you for your attention!

Sometimes each user has to format the hard drive, for example, before reinstalling the OS. But what to do if the hard drive cannot be formatted?

from 80 rub. RUB

The hard drive acts as a repository for all the data that is processed by the computer during its operation. As a rule, all drives of this type (HDD), which are also called “screws” among advanced users, regardless of their high-tech status, tend to lose their functionality.

Most often, users turn to our service when their hard drive cannot be formatted. However, solving this problem is not at all difficult if you entrust such a task to qualified specialists.

Our technicians have extensive experience and the necessary equipment to provide their professional services at the proper level and erase the hard drive. In most cases, failures in the operation of the hard drive are explained by the most common software imperfections of the device.

Diagnostics

In the case where the drive you are having problems with is not a solid-state technology, its functionality is achieved through the interaction of electronics with mechanics. It is this symbiosis that ensures the correct functioning of your hard drive, as a result of which you can capture the special sound that is produced by one or more rotating plates.

It should be noted that in some cases, such noise is also mixed with the resonant clicking sounds of the positioning device.

All of the above indicates that the drive is working properly. If we take into account the fact that the OS works without any failures or defects, except that the hard drive is not formatted, then replacing the hard drive is absolutely not necessary.

Cause of malfunction

Usually the main reason when the system does not protect a specific area of ​​the hard drive is the user himself.

Due to insufficient knowledge, a novice user cannot always predict what exactly the results of his actions may turn out to be.

At the same time, the desire to optimize the functionality of a hard drive as much as possible using a special service program in most cases leads to very disastrous consequences.

Changes that were made to the operation of the HDD unknowingly have an immediate effect. Moreover, not every user is able to identify such metamorphoses.

Only after a certain period of time, when the OS already requires reinstallation, when those who like to experiment have the need to get rid of all the information on the screw, or to partially format its partition, this procedure is not crowned with success.

SMART technology

This technology can also be interpreted as a disk soothsayer. It acts as a kind of health journal for your hard drive. Due to the internal evaluation of the drive, the user has a chance to quickly take the necessary actions aimed at maintaining the correct operating state of the hard drive.

If any fatal uncertainty arises, then you can always replace the non-removable storage medium with a previously corrected HDD, or a new one, knowingly copying all the valuable data from the dying screw.

Therefore, if you do not want to risk all the information that is stored directly on your hard drive, then it makes sense to carry out preventive measures, while enlisting the competent support of software that is specifically designed for this.

The best option would be to seek professional help.

If the hard drive is not formatted

Before you start panicking, it is better to take an adequate look at the problem that has arisen and assess its seriousness, as well as consider all the nuances of your possibly erroneous actions.

It will not be possible to apply the “format” option to the system disk while being directly in its own environment.

It is also impossible to remove an OS that is located in another section of the HDD, taking into account everything described above.

For example, using an operating system that was installed in the “C” partition, it will not be possible to format the local disk from another copy of Windows that was recorded earlier.

Antivirus programs often oblige their users to comply with a specific rule they create, which prohibits low-level access to hard drive partitions. If necessary, this option can be disabled in the corresponding settings menu.

If we talk about the interference of third-party applications and the harmful effects of multi-level viruses, then they can become obstructive elements, due to which the user will have limited rights. This, in turn, risks the fact that the hard drive will not be able to be formatted properly.

Restoring functionality

If you decide to reinstall the operating system, then naturally you will need to clean the corresponding partition of the HDD. And here the problems begin - this process is constantly interrupted, never having time to reach its successful completion, or freezes for an indefinite period of time.

In this situation, only specialized programs that are specifically designed to solve this kind of hard drive problems will help. A free option is the popular and in demand “HDDscan” utility.

It is designed for low-level diagnostics of the hard drive and allows you to monitor the condition of the HDD. It can become an indispensable tool with which you can repair bad sectors, format a disk, and also do various tests.

It is necessary to emphasize that this program is loaded not only from DOS, it can also function in a Windows environment.

You can use it immediately after downloading. You just need to run it with administrator rights. Next, click on the spherical icon that is located in the middle of the utility interface and select the “Surface tests” option.

As a rule, a partition with a hard drive cannot be formatted due to BAD sectors, namely their presence. To fix this, they need to be wiped down. To do this, use the “Erase” command. This can be done by placing a marker in the appropriate field.
