There is no volume with a raw file system. Ways to restore access to a “RAW” disk. Using the TestDisk program

Every operating system contains storage devices, and for them to work, a file system is required. With its help, the computer converts information (photos, music, videos) into binary system, in other words, in a language understandable to oneself. After this, the data is organized and further transformed for viewing by the user.

Storage devices- This is very vulnerable technical equipment. Damage occurs both in the logical partition and in the physical partition. Most problems associated with hard drive are fatal and require replacement of equipment, but there are also solvable problems. File system RAW is of this type.

Raw file system - what is it?

As was previously said, hard drive has a file system. The most popular are NTFS and FAT, which can be used for both hard drive, and for flash drives.

But what is the RAW file system? No matter how contradictory it may sound, this is the absence of any system at all! In other words, this is a critical error in the existing file system and Windows does not recognize it. It occurs due to the inoperability of the file system. As a result technical information information about the media is not displayed and access to files is impaired.

Let's look at the features of the RAW system
1. Access to the device is denied, and if the file system on your computer or laptop is faulty, Windows will not boot and you will see an error.
2. If such an incident occurs with a removable drive, an advertisement will pop up telling you about the need for formatting.
3. Open the “properties” of the drive and in the displayed information column, you will see “File system type – RAW”.

Why does the flash drive have a RAW file system?
For such drastic changes to occur in the file system, one reason from the “gentleman’s set” is enough:

Incorrect shutdown of the computer, power surge and disconnection of the computer from the network with a USB flash drive connected! Such treatment can also affect the computer’s file system and cause fatal problems with other components.
Operating system failures can also cause this problem.
The most common reason is viral infection. After all, it was not fools who came up with the idea of installing anti-virus programs.
Physical damage to the drive, which can also cause loss of information.
Processes occurring at the file system structure level. Problems with the boot sector, broken partition geometry values, etc.

The appearance of a RAW file system is not fatal in most cases, and recovery of user data is possible. There are exceptions, this is due to physical damage incompatible with life.
It is recommended to contact service center, where specialists will carry out the necessary operations to recover the flash drive and the data on it. This can be done with your own efforts, but you should be very careful not to aggravate the situation and not lose all the information.

To return the file NTFS system You can use one of these programs:

Hard DISK Format Tool,
Recovery Tool,
Acronis Disk Director.
Online service – RecoveryOnLine.
Reformat the disk to NTFS using MS Windows.

If using these programs did not help solve the problem, then in the global storage you need to find out which controller the drive has and reflash it, but this is a very difficult procedure and even experienced users may not cope. If even such manipulations did not help, then your flash card is dead.

Hard drive working normally computer device is always formatted in the NTFS or FAT file system. If one of HDD partitions starts to work incorrectly, an entry appears in the disk properties about converting its format to RAW. This means that the standard file system is damaged and needs to be restored. In practice, you can find out about such damage as follows. When accessing the disk, it does not open, and a message appears on the monitor indicating that it needs to be formatted.

What does this message mean:

The structure of the file system being used is destroyed.
There is no access to the contents of the hard drive.
Writing incorrect or damaged data to the boot sector of the disk.

When opening the properties of the hard drive, you will notice that the partition supposedly does not contain any information. In any case, it is necessary to restore the file system to return the data on the disk.

What could cause a crash?

The reasons for such a failure may be:

Impact from a virus that has entered the computer.
Critical operating system failure.
An incorrectly working program that replaces with its own files original files systems. This also includes “crooked” drivers.
User errors when shutting down the computer. This is how the file system on flash media is often damaged.
External factors that can cause damage to the file system. In particular, frequent power outages can trigger a similar problem.

How can I restore the file system and information on my hard drive?

Even though the operating system will prompt you to format the damaged partition, it is better not to agree to such actions. However, if you were in a hurry and gave the formatting command, all is not lost. However, in this case, it will be much more difficult to completely restore the contents of this section. First, you should restore all the information available on the faulty partition, and then restore the file system itself.

It is recommended to restore data and functionality of a logical partition using the RS Partition Recovery program.

This program allows you to:

Recover files from a HDD on which the file system has been changed. That is, with RAW.
Recover data from a hard drive that you formatted.
Getting the maximum complete information from the logical partition that was deleted.
Complete recovery of damaged partitions.
Copying data from damaged partitions to other media.
The program copes well with the assigned tasks on any medium.

Working with RS Partition Recovery

The program interface is quite simple. The main menu is divided into three main parts. On the left you can see a list hard drives And logical partitions. In the center, the disks are filled with information, as well as data on the sizes of all disks. The files we selected appear in the right column. The program even displays hidden files, as well as partitions managed by other operating systems.

It's time to move on to direct data recovery using this wonderful program. To do this, just click on the left top button, designated as “Master” (“Wizard”). The wizard's work menu will open in front of the user. The selected disk will be analyzed.

The program divides all partitions into three categories: logical, removable and hard drives. To restore data, you must select the appropriate partition. Specify it, and then click “Next”. You will be prompted to select an analysis type.

The choice consists of two options:

Quick scan.
Full analysis.

1 filter will detect NTFS system files. Most internal partitions operate in this space.
2 filter will process files, belonging to the system FAT. This formatting is more typical for removable media, but such files can also be found on the computer’s hard drive. WITH FAT system also runs Linux OS.
Deep analysis works regardless of the file system. During its operation, the program simply finds on the disk all the files that were once there or are in the present moment. However, it is undesirable to use in-depth analysis alone, since some information may be lost. It is best to analyze a section using all three filters.

When choosing quick scan some files simply will not be found. Only intact files will be found, without any signs of damage.

After completing the analysis, the program will tell you how many folders and individual files were found in this section.

To view all files found during analysis, you need to go to the main menu of the program by clicking the “Finish” button.

Hello admin, question! RAW flash drive file system, how to fix?

I took a flash drive to work yesterday and connected it to various computers, copied information back and forth, in short, I worked with a flash drive, and today I connected it to my laptop and this warning popped up: “To use a disk in the F: drive, first format it. Do you want to format it?

As I understand it, if you click on the Format disk button, you can finally say goodbye to your data on the flash drive, which is very important to me. What can you do to recover files on a RAW flash drive?

RAW flash drive file system

Hello friends! If you don’t need the data on the flash drive, you can simply . If you need the data, then read on.

When the file system on your USB flash drive suddenly turned into RAW, then this Means that the file system on the flash drive is seriously damaged. This problem occurs for various reasons: system failures, operation malware and so on. In this case, when you connect the flash drive to the computer, a warning will appear stating that the flash drive needs to be formatted into a normal file system: NTFS or FAT32.

In Explorer flash drive RAW will be displayed like this:

and in Disk Management it's like this

If you format a RAW flash drive, you will lose all your files on it, therefore, to save your data you need to resort to special program recovery software, such as DMDE. After the files have been restored, the flash drive can be formatted and returned to use.

Note: First of all, try to fix file system errors using the built-in Windows utilities chkdsk (sometimes it helps). Run command line as administrator and enter the command: chkdsk f: /f, where the first F: is the drive letter of the flash drive (in your case it may be a different letter), and the second /F is a special parameter that corrects file system errors when scanning. If chkdsk fails and will display an error WITHhkdsk is not valid for RAW disks, in this case you can use the DMDE program and similar ones.

Program DMDE is relatively free, that is, it has advanced features that you need to pay to unlock, I want to say that to recover files on one flash drive free features the program is enough for your eyes and you don’t have to buy anything, but on the other hand, ifIf you like DMDE, it costs only 300 rubles.

So, let's download DMDE on the official website

http://dmde.ru/download.html

Let's launch executable file dmde.exe.

The program works without installation, which is very convenient.

We accept the license agreement.

On the left side of the window, check the box Physical devices , and on the right is our flash drive.

Click double click left mouse on the flash drive.

The contents of the flash drive are instantly scanned.

Go to the Found folder.

"All found + reconstruction".

"Rescan the entire volume".

A detailed scan of the flash drive begins using the program’s own algorithms for deleted files.

In the next window, DMDE opens the found folders with files.

Do not expect that during recovery the found folders and files will have the names you are familiar with. The names of the found folders and the files contained in them will be generated.

You can enter any folder and restore the files you need.

For example, I found all the photos I needed in these folders.

Double-click the left mouse on the selected folder and go into it.

We mark all found files with checkmarks and right-click.

Select "Recover files".

Yu.A. Peysakhovich:
Format the flash drive.

Ryzhanov Denis Ivanovich:
This flash drive needs to be formatted... In principle, this is almost always available standard means Windows XP.

Mikev:
Your RAW is most likely just an unformatted flash drive, because RAW means “raw”, fresh.

TU-154:
Either the flash drive has a password, is not formatted, or is simply faulty. Try formatting it with standard using Windows XP. You can also try tools for working with a flash drive from the flash drive manufacturer.

GIN:
Such a flash drive cannot be revived. Neither Windows tools nor programs from the manufacturer. As a rule, the operating system sees it as a device, but when formatting it is impossible to access the device. For 3 months I haven’t been vomiting, but it’s all in vain.

Deoniss:
write it all well, only raw is not a file system, but a simple one (a glitch) and it stands for: Read Error Rate. If it’s on hard drive, then from under dos it’s calm - format. But I haven’t had the chance to restore from a flash drive yet.

Serg:
This isn't necessarily a glitch. It can simply be encrypted, for example, TrueCrypt program. From the curious.

Oleg:
The other day the flash drive crashed (the computer turned off, but the flash drive was active). After turning it on, it was still recognized, but the next connection the operating system began installing the flash drive as a new device, after which it showed that the file system was RAW, volume 0. So this is not encryption from the curious - it really is a crash.

Zed:
And if this happened to local disk? This happened for no reason, after reinstalling Windows!!! on it important information and it cannot be formatted! What to do?

NED:
What to do if the flash drive with RAW is not formatted?

Espair:
I had a similar experience. This is a disaster, just throw away the flash drive.

Sharap:
Try to start new installation Windows on this flash drive, the computer should see it as an unformatted partition, and when, after formatting this partition, the computer wants to start installing on it, turn off the computer! It helped me!

Fish:
Restorer 2000 can extract some information from under RAW.

Djinny:
1. The flash drive contains valuable data. We install the Easy Recovery Professional program and try to restore it. If it works, then calmly format the flash drive (it doesn’t matter from what - for those who can only do this under DOS, I recommend using an antivirus). 1.1 It didn’t work out, but the data is VERY VALUABLE. We carefully take the flash drive to the service center, where for a huge amount of money and considerable time, this matter CAN be restored for you. The method is to transplant the memory chip itself into a similar working device. If the memory itself is intact (usually yes), then it helps 99%. 2. There is no valuable data. We are trying to format it, just for Windows. It didn’t work - using some convenient utility (parition magic) we try to delete the raw partition and create a new one. If it doesn't work, throw it away.

Hard drives ( hard disk drive - HDD), which for various reasons are not detected operating system, receive RAW status and access to them is terminated. When you try to open such a disk, Windows advises you to format it, but if you follow this recommendation, all recorded information will disappear. It is advisable to restore an acceptable format: NTFS or FAT32.

The sources of problems with the HDD can be different, and before doing anything to restore the format, it is worth identifying them. Here are the most common:

Connection failures. For example, the user incorrectly disconnected the disk or the power supply stopped and the file system became corrupted.
The cable that connects the drive to the board is broken.
Malicious software that violates the data structure.
Errors that occurred when reinstalling or updating the OS.
In the case of a flash drive, the reason for changing the format to RAW may also be a malfunction of the USB connectors.
Malfunctions motherboard PC.
Errors when working with Acronis Disk Director.

Format recovery

To restore NTFS format from RAW, try the following:

Restoring format using special programs

If, when you try to check the HDD using the method described above, a message appears: “CHKDSK is not valid for RAW disks,” you can use programs that allow you to restore the NTFS format from RAW. Let's look at the most popular of them.

DMDE

DMDE is a utility that looks for damaged partitions in the file system and helps restore the disk to NTFS status. After downloading and installing the program, you need to do the following:

Launch the application.
On the left, check the box next to the phrases “Physical devices” and “Show partitions”.
Select the damaged drive and click OK. After this, the utility will find the RAW section and indicate it with a crossed out icon. If this does not happen, perform a full scan (the corresponding button is located at the bottom of the window).
Now try to open the RAW volume and click “Recover” and then “Apply settings”.
After this, as a rule, the HDD format changes to NTFS.

DMDE program window

IMPORTANT. If you are trying to revert to NTFS status system disk and do this from another PC, then after the operation is completed and the HDD is returned to its place, the old computer will still display it in RAW format, so it is advisable to first restore the Windows bootloader.

Recuva

A simple and easy-to-use program that can fix RAW disks and flash drives. The procedure is as follows:

Launch the application, select “Recover all files”, mark the damaged disk and click “Start”.
The utility will detect files with a broken structure and correct the format to NTFS.

Piriform Recuva program window

TestDisk

The third utility that restores the disk format. Just download and run it, and then:

Select New, press Enter.
Then click on the problematic HDD, then Enter again and select Analyze and Quick Search.
After executing the command, select Write to restore the information structure.

TestDisk window

If all these manipulations lead to nothing, most likely the disk has mechanical damage or its components do not interact correctly and it would be more advisable to show it to a specialist.
