Most often, the file system of the disk changes to the RAW after incorrectly shutting down the computer when the light is turned off, or the user saved the time and pulled the power cord of the system unit from the socket. Another reason - viruses that change NTFS on Raw format HDD discs. How to fix this problem, read in this article.

What is the RAW file system?

If the disk received the RAW format, Windows will display it among other sections of the hard drive. But when attempting to open the computer will give an error and prompts it to format. In addition, any actions with this volume will be unavailable: error check, defragmentation, etc. (useful to read "How to check the integrity of Windows 10 system files and restore them?").

As such a file rAW systems does not exist. If the disk receives such formatting, it means that the computer driver is not able to determine the type of its file system - NTFS, FAT or FAT32. In practice, this happens in several cases:

• the structure of the file system is damaged;
• the section is not formatted;
• there is no correct access to the contents of the volume.

If the Tom is damaged to the OS, the "Reboot and Select Proper" will appear when the computer is loaded boot Device."Or" Operating System Not Found ".

Restoration

If the problem arose on a non-system disk, but it contains important informationwhich when formatting will disappear, use regular Windows or third-party programs To correct the error.

Windows tools

Mainly fix the problems with formatting in RAW helps the staffing utility CHKDSK.

After checking the computer will restore damaged sectors and file System NTFS on a problem volume.

Important! This method is effective if the Winchester flash drive or disc was formatted in NTFS.

Also the chkdsk utility will help when damaged system Disk. But for this you will need a boot disk or flash drive.

1. Run the computer from the boot flash drive or disk → select "System Restore".
2. Advanced Options → Command Line → Enter chkdsk Letter_ad_Disc: / F.

In the recovery environment, the letters of sections differ from the name logical disks. So as not to be mistaken, open in command line List of computer partitions.

Enter DiskPart → List VOLUME → The list will indicate which disc system.

Third-party programs

There are third-party programs that help restore the NTFS file system, if for some reason it has been reformatted in RAW. They do not damage the information of the user, stored on the volume, in contrast to utilities chkdskwhich in the recovery process can "hurt".

MINITOOL POWER DATA RECOVERY

Important! This method is most effective if the RAW file system appeared on the flash drive.

Testdisk.

This is multifunctional free utilitypartition hard disk Using a large number of options. The program is represented by B. portable version, Therefore, it does not require installation. The main minus TestDisk - no Russified interface.

1. Download the archive with the program → Run the file testdisk_win.exe. On the name of the administrator → select "Create" → ENTER.
   
2. With the Up / Down Arrows, select the desired disk → ENTER.
   
3. Specify the desired type of partition table (the utility will make it automatically) → ENTER.
   
4. To search for "lost" sections, select "Analyse" → Enter → Quick Search → Enter.
   
5. The utility will find "lost" volumes → Press "P" to view a list of files.

Today we will look at how to restore information from a hard disk when damaged the file system structure, when the RAW file system is displayed in the disk properties. Below it will be about several ways that will allow you to restore the disk with the RAW file system.

Immediately you should pay attention that does not exist universal Fashion eliminating the problem. Below we will look at a few most effective waysallowing you to restore the disk.

Causes of RAW File System Display

1. The disc was not formatted. However, if earlier the disk worked fine, then this reason marked;

2. There are damage in the file system structure;

3. There is no correct access to the disk;

4. In the boot sector or MFT erroneous data is recorded.

Ways to restore the RAW file system

Method 1: Disc Checking

This method must be produced by users first of all, because It launches standard windows toolswithout resorting to the help of third-party programs.

To take this way, you will need boot flash drive With Windows.

Log in to the BIOS and install the flash drive as the default boot device.

RAW file system and how to return NTFS

Today, we consider how the RAW HDD format appears, what is the RAW file system, why it is needed and what to do if one of your disks decided how invalid, not marked, not formatted, damaged. We will also consider how to do when it is written that "CHKDSK is invalid for RAW disks" when trying to correct the situation with funds operating system.

The RAW file system is in implicit form is present in NT operating systems from Windows Corporation. It is created with a single goal - provide applications and operating systems data on the volume of the current volume and the name of the file system used on it (FS). If you got a RAW partition on hard or solid-state accumulator (Flashkeeper, SSD), this means that the file system of this volume or drive was not recognized by any driver file systems installed in the Windows used environment. That is, the file location structure is clearly different from NTFS and FAT / FAT32. The consequence of this is such errors as:

• the message is that the drive / partition is not formatted in a well-known file system;
• there is no possibility to carry out normal access to the device / section;
• the file system of the disk was damaged.

When one of the above alerts appears, further work with the volume is not possible in the mode of reading, nor, even more so, in recording mode.

Sources of the emergence of the problem

Most often, a similar error appears on a flash drive in view of improper handling or device wear, but also for hard disksEspecially removable, the problem is very relevant. Its sources in most cases become:

• malicious applications interfering with a file table or volume structure;
• partial damage to the boot sector or file Table volume;
• damage to the file table, which contains information about all stored data;
• physical damage of volume sectors contribute to the fact that the type of file system is called, called RAW;
• improper extraction of the flash drive or abnormal modes of the device (voltage jumps, the disappearance of the electricity or incorrect PC shutdown).

Options for treating disk or partition

Depending on the reasons for which the RAW format appears, instead of FAT / NTFS, there is a mass of methods to access the stored information on the information device.

Tom checking for damaged sectors and errors

The first step that should be done if the file system of the disk or flash drive is defined as RAW, it is checking damage on the drive or its logical section. For the case when the system volume is not defined, this Recommendation Not suitable, but in other situations should be started with it.
Call the command line on behalf of accounthaving the privileges of the system administrator via Winx or search string.

In the black window, we perform a command of the form: "Chkdsk X: / F / R".
In this case:
X: - Task Force;
/ F - the flag responsible for correcting errors;
/ R - the argument will allow you to find and correct non-working sectors.

We wait for the completion of the operation and try to open a problem volume.
If the error "CHKDSK is unacceptable for RAW disks" is appeared as in the screenshot, it means that the target volume is systemic, and for its verification we do the following.
Run PC S. installation media Windows of the same editor and bit.
On the screen selection screen click "Next".

Go to the diagnostic section and open the list of extended parameters.

Run the command line.

Let's pay "diskpart".
Team "ListVolume" learn the letter of the problem volume.
We leave with diskpart by entering "exit" and confirming its execution by the "Enter" button.
We perform the command of the type "CHKDSK X: / F / R".

Thus, you can return control of the disk without losing any data.

In this case, the inscription "CHKDSK is unacceptable for RAW disks" should not appear if this happened again - we go to the next subsection of the article.

Checking the integrity of the files itself

Often, to convert Raw to NTFS, you just need to resuscitate system files. This is done not more difficult than the search for damaged sections of the drive.
Call the "Perform" window with a combination of Win + R.
Perform "CMD" to run the command line.
We perform "SFC / SCANNOW" to start the utility that will delete and correct errors in the operating system.

Format the section in the absence of important information on it

Disk or RAW flash drive, on which there are no files (for example, only purchased the device), there are no important data or are duplicated, easily converted with RAW on NTFS Windows tools.
Call the "Run" window by combining the Win + R keys.
Perform the "diskmgmt.msc" string to invoke the disk management utility.
Through the context menu of the problem partition, call the "Format" command.

We specify the desired mark and determine the file system (it is better to choose NTFS), then click "OK".
If removable hDD (Its partition or flash drive) is not formatted, try disconnecting the removable device if it is so, and then connect and repeat the attempt. In the case of HDD, restart the PC, and be sure to complete all programs that the problem volume can use.
Now you know how to fix the RAW format HDD and flash drives, but the formatted media will not contain the source data. If the option to format the drive or disk is not suitable, go further.

HDD Raw Copy Tool

The HDD RAW Copy Tool utility is designed for sectors of copying media and allows you to extract all data from a problem device without data loss.
Download the utility from the official support resource application.
We install and run HDD Raw Copy Tool and wait until the sections found in the main frame will appear.
Select a problematic device from which you will subsequently restore information (there appeared a file system defined as RAW).

Click "Continue".
Indicate the file type as * .img to make the image of the recoverable disk.
Here it should be borne in mind that when you specify the path of storing the image, where all the files from the RAW disk will be placed, there must be more free space than the volume itself, which will be copied.

Returning to the HDD RAW Copy Tool interface, where we press "Continue" again.

After that, you can safely open the generated image through the program to resuscitate data that supports working with images, for example, R-Studio, and start restoring the desired data, and just a copied media format in NTFS.
How to restore data from the image, to paint do not mean a large amount of information that is enough for another similar article.
On this HDD Raw Copy Tool you can close.

Dmde.

The previous method although it is highly reliable, still working with the original source is much safer and more reliable. Consider how to reanimate important filesIf a RAW format appeared for one of the HDD disks. Here we will do without formatting, so if some disk has become RAW, you can easily access all of its files below the method below.
Go to the dmde.ru and load the DMDE utility, allowing you to read the disk in such format as RAW and restore it.
Working with the program consists of such a sequence of steps.
Select the physical disk where the section with the RAW file system is found by checking the FIZ option. Devices.

When detecting necessary section Choose it and click "Open Tom."
If this does not happen, we carry out the media scanning, the file system of one of whose sections began to be defined as RAW.

We open the volume and look at its contents - whether the files on it are located.

If all is true, click "Restore" and confirm the restoration of the boot sector.

If everything happens properly, after a short time dMDE program It will restore the lost section, without bringing the change, and will return to him the former file system.

Attention! If the system volume was problematic and the recovery was made by booting from another disk or after installing the media to another computer, you will additionally have to resuscitate the bootloader.

Testdisk.

The TestDisk program is the most complex in operation, but also holds the best volume restoration with the RAW FS. Launch installed application, Perform the following actions:

Click "Create", then select the target partition.

We are determined with the partition type, if this does not happen automatically (MBR or progressive GPT).
Click on "Analyze" and click "Enter".
On the next screen, press "ENTER" again by selecting the Quick Search item.
We find a section to restore data from the disk with the RAW file system.
To view the files stored on it, click Latin "P", output from the post mode - "Q" button. If the section has a mark p, it can be reanimated, the volume with the mark D will not be restored.

Make sure that the table shown on the screen it will be after resuscitation is correct.
Here you should be confident in the correctness of the choice, but also to become a coward and do not do anything.
We select "Write" and confirm the implementation by clicking "Y" in order to execute RAW Recovery.

The change will take effect after restarting Windows.

On this topic "How to change the file system if the disk has a RAW format" can be considered completely lit. Difficulties in solving the problem, as you can see, absolutely no.

What is RAW really? In essence, such a FS (file system) RAW is not at all.

In practice, the file system of such a partition as RAW means that the name of the disk system or any partition is none of the FS driver (file system).

If the FS disk is recognized as " Raw.", Then assigning volume tags, reading data and other actions with a section or disk becomes impossible. At that OS, it displays the container of the partition, and when accessing it, it advises to format the partition.

1. Hard Raw Disc

If the OS is unable to recognize any file system of the disk, it automatically displays it as a RAW. Thus, the user will not receive access to data and disk partitions. But its capacitance, free memory and other space will be displayed in the form of the figure "0". This means only one thing - all the disk data is lost. They are also unavailable for copying and viewing.

2. RAW section on hard disk

It often occurs in such a way that as a result of any attack or damage is displayed as RAW one section of the disk. When you try to interact with such an OS partition, it will give an error and suggest formatting it.
Formatting the proposed partition, it will again become available for use in the future, but will lead to the loss of all data that were in it before formatting.

3. Why the hard disk or partition becomes RAW

The reasons for such problems are very different, I will try to summarize them.

For hard disk:
- Cable disk or connection is damaged. It happens that the hard disk is defined in the form of RAW if the connection cord is not suitable for the connector, or it is damaged.
- the so-called "broken sectors". A large number of Such "white" sectors on the railway leads to damage to files and file systems as a whole.
- The structure of the file system is damaged. The file system may be damaged not only because of bied sectors, but for other reasons.
- Section tables are damaged. If for some reason the partition table is damaged, then the entire disk will be defined as RAW.
- Restoration or full reinstall OS (operating system).
- action of viruses. Viruses, malicious software and so on can remove some important parameters, Change them, thereby damaging the information of the railway.

For hard sections Disc:
- Malicious software and viruses. Programs that contain viruses, ways to damage parts of the table or railway partitions, which causes information damage.
- Reinstalling the system (Windows).
- Many hard drives and sections. A large number of sections and disks on the PC can also lead to the occurrence of RAW sections.

4. How to recover RAW disk

In the event that the data on the RAW disk does not have a special value and Windows is loaded.
The fastest and most reliable way to restore the RAW disk or its partition. In this case, we will only need to format it to use it further fully.

You must understand that recovery and data saving is not available. In the error occurred from Windows, click on the button " Format disc».

If the OS did not inform the user about the error, but in the disk properties it can be seen that there is no file system or disk in the My Computer folder, then the formatting may occur using a special "Disk Management" menu.

Go to the "Disk Management" section through "Start". In the window, find the desired disc with the RAW file system, it will be directly signed. Next, click PCM on it and select "Format".

In the event that the data on the RAW disk is valuable Windows loaded

In the event that these sections or disk are important, but they are determined in the form of RAW, do not rush to format the section or disk as a whole. Try to check the disk for errors, and later fix them. This can be completely, or to restore the performance of the partition or disk.
- Go to "Disk Management", as this is described above.
- Remember the name of the disk with the RAW file system.

- Navigate to the command line. In the Start menu, look for the "Command Line" section and run it "on behalf of the administrator."
- In the opening window, enter the chkdsk d: / f, where D is the letter necessary disc And confirm with the ENTER button.

After the command runs the process of checking and correcting will begin. At the end of Windows will notify the correction of errors. Try again to go to the section and interact with files again.
Windows is not loaded, and the disk on which the OS is installed is defined as RAW

If the installation disk is missing:
- Disconnect the hard disk from the computer itself and connect the hard drive to another. Using a new computer, check the disk on the error and use the above program to restore the data.
If the installation disk is available:
- Load the PC using this setting disk and instead of installing a new OS, select "Restore Computer".

- In the recovery menu, you need to find the command line item. Start it and check the disk on errors.
What is needed for this:
- In the command line that opens, enter NotePad, as a result, you must open a notebook.
- Select "File" and "Open", so check the letters of your disks.

- In the command prompt, check the disk from the OS.

Data recovery using RAW disk programs

If none of the ways helped, you can try to use programs for data recovery.

To do this, you can try to use the programs: "Raw Recovery" or " Partition Recovery.».

Consider the data recovery process from disc Raw. With the help of the second pARTITION programs Recovery.

After starting the program, you will be provided with a list. existing sections and discs of this PC. You need to click on the RAW section twice. In the picture Rav-section under the letter E.

The program feature is that it can work with any file system. It displays the file systems automatically without the user's additional settings.
You just need to choose the "type of analysis" and wait for the end of the check.

The analysis process, usually occupies from 15 minutes. Scanning speed depends directly from the disk volume. As a result, the program will show all the files and put them in folders.
Everything required files You need to add to the list and click on the Restore button.

.

Almost every user faced the error of the RAW file system, and wondered how to return NTFS. To begin with, I would like to dwell on the reasons for the appearance of this RAW itself and bring some terminology.

So, RAW is not the file system at all. In this way, the OS identifies an unknown structure. By the way, RAW is translated from English - raw material / raw material. NTFS - NEW TECHNOLOGY File System.translated from English - file system new technology.
You can call a series of features that will help identify the problem when accessing it or its partition. Windows can return the following dialog boxes and messages:

Resetting the disk structure to the RAW type from NTFS and the appearance of such errors may contribute to the following factors:

• sharp voltage jump;
• incorrect power discs from nutrition;
• incorrect update OS at any stage;
• bad sectors;
• unstable work motherboard;
• damaged cables;
• viral attack;
• if the error occurs at a USB screw / flash drive, it is necessary to check the connector itself.

There are a number of ways to return the file system in NTFS from RAW, but we will start with the one that minimizes the risks and helps save the data structure and the data itself. So, how to return the disk in the RAW format in NTFS without losing data? Consider several ways in order, starting with the simplest.

Classic Restart.

No matter how trally sounded, but a simple reboot sometimes helps to return the file system from the RAW in NTFS. It's connected with temporary failure. If this method does not help, go further.

Check connections

1. If you have a desktop PC and it is not under warranty - open system unit And carefully check the integrity of all wires, connections and their dense adjacent. Check did not find anything, try simply to reconnect the disk into the free connector on the motherboard.
2. If netbook / laptop, regardless of warranty or not - contact the SC.
3. If we are talking About removable media, reconnect it in another USB connector. If the situation is repeated, check the USB performance by another device - mouse, keyboard, other media, etc.

First need to exclude a physical malfunction, and after switching to software decision. The above methods did not help return the file system from the RAW in NTFS? Go ahead.

Check DISK will help with NTFS

Checks hard drives and removable media for the presence of bugs in the file system with further correction. In some cases, this will help return the PC to the working condition.
Run CMD with elevated privileges:

No access to cmd?

There are absolutely different situations: if Windows does not load, then there is no access to the command prompt. Naturally, the Check Disk Utilities with SFC is not possible.

1. Use live discs On CD / DVD / Flashke.
2. Use boot disk or Flashka to restore NTFS:

To avoid errors, use the DiskPart utility:

After rebooting, do not forget to return the boot device - set the system disk.

If you have a desktop PC, the hard drive can be turned off and connect to another and already from another operating system to start the check.

Antiviruses will be returned NTFS

Check the system for viruses. Such as:

• MalwareBytes - Trial version works fully for 14 days, you can download from the official site.
  https://ru.malwarebytes.com/Premium;
• Dr.Web Cureit! - Free to use the house, you can download from the developer's site by moving on the link.
  https://free.drweb.ru/download+Cureit+Free.
  By excluding a viral attack, and if you failed to return the normal file system, go to further instructions.

Formatting or how to return NTFS

One of simple ways Return the normal state of the hard drive is the formatting of the disk, but this can be done only if nothing is important is stored on it. Convert RAW to NTFS can be built-in utility Windows - diskmgmt.msc.

Third-party funds to help the NTFS file system

Return the File System with RAW in NTFS can and proven third-party funds that have proven themselves from the best side.

Recuva - from the well-known developer Piriform, they also created CCleaner.
