The best programs for recovering data from a hard disk. Simple data recovery

Need to recover damaged JPEG files? Looking for a way to recover damaged files? Your files do not open after data recovery or open with an error - "File is damaged"? JPEG files are available only in a small size ("preview")?

Use Hetman Software programs in order to properly restore remote files, or correct errors in the files of the HETMAN program File Repair..

Signs of damaged JPEG file

JPEG is the most popular and distributed image format and photos. And so, as the files of other JPEG formats may be damaged as a result of any errors, failures, viral attacks, network errors or software failures and system failure.

Damaged JPEG files may not open the program to view digital images or open, displaying explicit damage. Often, trying to open a damaged JPEG file, it opens in a distorted form or with such a message, such as: Photo Viewer cannot open an image, as it is damaged or similar.

This is a problem situation, since in any of the cases your files become inaccessible to use. But you should not be upset, such files can be restored using special programs to correct damaged images.

Damaged file restoration methods

Before using the software tool, you can also try to restore the file on your own:

Click on the file right-click and change the extension of the file S.jpeg by .jpg or vice versa.
Try to open a damaged photo using another tool for viewing images, it is possible that the program error is for viewing photos.
Open your JPEG file with one of the tools for editing images. Sometimes, in this way, you can open the image and save it in another readable format.
We also recommend trying to open the image using a webbuser.

If, with any of the presented options, it is impossible to open a JPEG image or open it without explicit distortion, you can do this using a program to correct JPEG files.

To do this, it is enough to download, install and run the HETMAN File Repair. With this tool, you can easily and safely correct most image errors and photos.

Using trial version Programs, you can check the efficiency of the program in your particular case with your images on your computer. You are given the opportunity preview All image recoverable. And only if you are arranged the result of the free version of the program you can register it for further use.

Price: 2 999 rub.

The article describes the principles and methods of software recovery data for users who do not have special knowledge.

If the value of the information is very high and / or the media has physical damage - it is worth thinking about contacting specialists. In this case, the probability full recovery The data will be the highest.

With independent data recovery, it is worth notifying the following information:

Recording to a section with restored information may reduce the likelihood of data recovery, as the data can be recorded on top of existing. This also applies to the installation of data recovery programs and save recovered files.
All work with the source drive is desirable to minimize to increase the chances of recovery. Good practice - creating a sectoral copy of the drive and use various methods Recovery to copies.
If the information carrier has physical damage (primarily it concerns hard drives), then any impact may aggravate the situation. Continue restoration independently follows only when the value of the data themselves is lower than the cost of their recovery by specialists.
Checking disk for errors windows tools Create additional difficulties for data recovery, up to the complete inability to restore them.

Disc structure

For a better understanding of further actions, we will tell about the logical structure of the disk and file systems. If you are not interested in the theory and you need to quickly restore the data - you can skip the section and go directly to the action algorithm.

MBR

Master Boot Record is the main boot record - is located in the zero disc sector, contains a part of the executable code, as well as data on four sections and how the section is bootable.

If MBR is correct, then after receiving the control code contained in it, reads the partition table and transmits the code control contained in the first sector boot section (VBR - VOLUME BOOT RECORD), if it contains 55aAH signature at the end of the sector.

Otherwise, an error message may appear, for example: "Reboot and Select A Proper boot Device."Or" Invalid Partition Table "or" Missing Operating System ". All listed messages may occur both due to malfunction in MBR or VBR and for other reasons (incorrect boot disk etc.).

To restore a damaged MBR or boot partition, there are specialized utilities such as TestDisk (Windows) and GPart (Linux), you can also use the "Recovery Console" from the installation windows disk. Their application will not always give positive result When data recovery, since other malfunctions may be other faults, so these options will not be covered in the article. And although there are enough instructions for eliminating such faults in the network, it is recommended to first restore important data from the drive, and then try to restore its proper work.

File Systems

Any partition containing the file system consists of the following parts:

Download area (VBR), which contains information about the partition structure, as well as executable code.
The data area that is divided into equal parts, called clusters, and each cluster has unique number. The cluster size is set when formatting.
The area of \u200b\u200bthe file system data system in which information on folders, files, their names, attributes, as well as information about which cluster chains is occupied by one or another file.

Locations of parts, as well as copies of service data depend on the type of file system.

Consider more details the most popular file systems on custom computers: FAT and NTFS.

NTFS

The structure of the NTFS file system is schematically shown in the figure.

A section of the boot area begins, which contains information about the section, as well as executable code. A copy of the loader is most often at the end of the section.

The following area is the main table of MFT files (Master File Table). It is in it that information about directories, files and their attributes are stored. Usually under the MFT, the disk area is reserved equal to 12.5% \u200b\u200bof the partition size. The size of the reserved area may vary (both in greater and in a smaller side), and the table itself can be fragmented.

In addition, a certain section of the section contains a copy of the first 4 table service entries.

The user data area occupies the remaining partition space.

When deleting a file standard means OS in the file record is made only a mark that the file is deleted, and the place occupied by them is marked as free. If, after deleting the file, no entry to the disk was made - the file remained in place, and its restoration is possible.

When formatting a section There is a new MFT on the place of the old. Initially, the size of the new table is sufficiently small (several hundreds of MFT entries), so some service records of the previous file system can still be restored. The more files were recorded on the formatted section - the less likelihood of successful data recovery.

In this case, the data is physically remain in their places, some of the information about them stored in previous version MFT. This files are not possible to read these files.

Sometimes complete formatting is called low-level formatting, which is an error. Low-level formatting - The technological operation, which is manufactured in the manufacture of the drive, and it is impossible to implement the software methods.

Actually from operating system Only high-level formatting of two types are available: full and fast. Fast formatting simply generates a partition table, and with full formatting, the entire disk is checked first for damaged sectors. In Windows XP, this check occurs using the reading operation (that is, the data remain in place, and it means that this situation does not differ in the recovery issue quick formattingThe above), and in Windows 7 sectors are checked by a record, and the data are permanently destroyed, and there are no ways to restore them.

Fat.

The structure of the FAT file system is schematically shown in the figure.

At the beginning of the section there is a VBR, its copy is usually via located after 6 sectors. Through a certain amount of Sectors are the FAT file itself (File Allocation Table), followed by it - its copy.

IN file table Information is stored only about cluster chains that occupy files. The names and attributes of the files are stored in the directories, which are located in the user region.

The user area in FAT begins with the root directory, all other directories and files are located in it. Directory entries indicate the first entry in the file table, which contains information about the file clusters.

When deleting a file There is a change in the first file entry symbol on special codewhich means that the file is deleted. Also marked with free clusters and delete information about the cluster chain, which occupied by the file, which complicates the procedure for restoring fragmented files. The data area remains unchanged, that is, the files are still possible to restore.

When formatting A new file table and root directory is formed, the table size is indicated at its start. The data itself, in the general case, remain on the disk. What follows the disk after the newly created table remains untouched (that is, information about the location of the files that were on the disk to formatting). As new files record, these directory structures and files are replaced by new, reducing the likelihood of restoring the existing information.

Data recovery methods

There are both pure data recovery methods and software and hardware. For the latter, special expensive equipment, relevant experience and knowledge, is needed, while software recovery using automated utilities is available to almost any PC user. This method will be described below.

Restore remote files

To restore files remote by standard tools of the operating system, you need to read service data, bypassing the interface of the file system. In this case, you can get information about the location of the files that are noted remote.

If the subsequent recording on the disk was not made, then this location will be read by the desired file.

Reconstruction of the damaged file system

This method is applied in the case when the file system was damaged or formatted. To reconstruct the file system, you must scan the entire partition to search for service data residues, on the basis of which the file table will be played and, if successful, access to files and folders stored in the section will be received.

Recovery after changing the structure of the disk partitions

Specialized utilities scan the drive for the presence of file systems structures that are available on the disk. Based on the scan, a list of possible file systems is built with a preliminary assessment of their state. The next step is to check the systems found for the presence of the necessary data.

Recovery by signatures

RAW-Recovery - recovery by signatures, is used in cases where other methods have not given a satisfactory result. In this case, the storage devices are sectors for the presence of known signatures (a unique character set characteristic of a specific type of files).

For found files, neither the name nor the logical location nor attributes are unknown. In case the files are fragmented, this method Recovery will be ineffective.

If the starting file signature was found, then the next task is to find the end of the file. Usually, any next known signature is used for this, which can give an unsatisfactory result. Modern programs apply methods that use the remaining data on the file system and its features to improve the result. In some cases, such algorithms can help restore even a fragmented file, which is not possible when using standard algorithms. For example, the IntelliRAW algorithm used in the UFS Explorer family programs works in conjunction with the file system reconstruction algorithms and uses the information obtained to determine the end of the files. Such implementation allows you to achieve better results than when using simple methods Recovery by signatures.

A good result of rough recovery can give in the case when the files on the drive are located sequentially, without displacements and fragmentation. For example, when recovering files from memory cards, cameras, video cameras, etc.

Algorithm of data recovery

Algorithm we give on the example free program which is available for non-commercial use on the territory of the former CIS. It is compact, easy to use and does not require installation. Uses commercial software algorithms, gives results at the level of professional utilities. NTFS, FAT and EXFAT file systems are supported.

You can download it from the support page on the official website :.

The archive with the program must be unpaved on a section other than which recovery will be carried out. In case the system is only one partition better decision There will be a disk connection with data recovered to another computer. If there is no such possibility, you can unpack the program on an external drive (if it is sufficient to save the data recovered).

Selecting section

After unpacking the program, it must be launched. On the left side of the main window you can see the drives connected to the system and partitions on them. If the desired partition was automatically found and displayed in the list - select it and go to the next item.

If the desired partition is not in the list (for example, a drive formatting or changing partition sizes), you can run the search for a lost partition or set it yourself (only if you know the exact partition parameters). You can choose these functions in context menu Drive either on Tulbar.

Consider the function of finding a lost section. Read more:

After it starts, a new window will open, in which you want to click on the "Find Now" button, which will start the search on the disk of known file systems. As they find them, the list will be complemented by information on the found sections. Most probable options There will be a blue icon, which means a good partition state. If the icon of yellow or red colors, then the partition found is either very damaged, or found erroneously (some types of files can give such an effect).

From the list of partitions it is necessary to mark with ticks those that most comply with the parameters of the desired section: the beginning (in sectors), the size (in sectors and megabytes), the label, the type of file system.

If the value in the "Size" column is less than the value in the "Start" column, then most likely, this section is not valid. Typically, these "incorrect" partitions are images of discs stored on the drive.

To continue, click the "Use Selected" button.

Scanning

If a partition with the NTFS file system has been selected, you will be offered a selection: run full or fast scanning.

Scanning scan area - search for files remote by standard tools of the operating system. With such a scan, only reading service entries in the file table and their analysis are performed.

Full scanning is used in most cases. At the same time, it is searched for removal of service entries in the file table, the virtual reconstruction of the file system and the sectoral scan using IntelliRaw technology. Gives an excellent result, but takes more time.

For FAT16 / FAT32 and EXFAT file systems, only the full scan mode is available. This is due to the fact that due to the features of the specified file systems, in many cases, quick scanning is not enough to effectively recover data.

Saving results

After the scan is complete, the program will show the result of the reconstruction in the form of a file tree and folders that managed to find.

Blue icons displays elements that are visible by standard tools of the operating system, the red - those that have been deleted or lost and are not available to standard tools for the operating system.

Also, service folders will be available:

Contains files and folders whose location failed to tie to the root catalog
Contains files sorted by type found by recovery by signatures (with IntelliRaw technology)

To save the recovered data either in the context menu of the item, select "Copy in ...", or click the "Mass allocation" button on Tulbar, then mark all the necessary items and click the Save Selected button.

Recall that it is necessary to save the recovered data only to a section other than which recovery is being conducted - otherwise the data may be damaged.

Looking for a program to restore damaged files? After recovering remote data, the necessary files do not open or open with an error message? Do not know how to restore the structure of damaged photos?

Restore damaged program files

Use the program to restore the damaged RS File Repair data. The program will quickly correct errors in the file structure and restore them in its original form. Step-by-step recovery wizard and interface in the MS Windows Explorer makes work with a utility light and understandable, not requiring special skills. Thanks to this, each user can quickly find and restore the desired files even after serious damage.

Download Log in Screenshots

With RS File Repair, you can "correct" files in two ways.

If you restore the data using the wizard, you can work immediately with multiple files, even if they are in different folders. The program will eliminate damage and save the files to the folder you selected.

If you do not use a wizard when recovering damaged files, you will be available to the preview function, and you can view the corrected files before saving.

Restoring damaged files using the wizard

To use a convenient step-by-step wizard to correct and save damaged files, select the "Master" item in the File menu.

In each new wizard window you will find detailed step by step instructionsthat will help you easily recover damaged files. If every time you start the program, you wish to start working with a wizard, use the "Display Wizard when starting the program" option.

In the "File Select" window you need to specify the damaged files that you would like to fix and save. Here you can add to the list of any number of files from various folders, delete files from the list or fully clean the list. You can also select a way to display a list of selected files ("icons", "list", "Table") and use sorting files.

Then select the type of analysis of the data being recovered. In most cases, it will be enough to use the "Analysis" function, which allows you to quickly eliminate damage to the logical file structure.

The second type of data processing is "Study" - is used if you need to analyze the file structure in more detail. It takes much more time, but allows you to restore even badly damaged data by saving the maximum amount of information source files.

In the next window, the wizard will prompt you to choose the path to save the recovered data (the folder to which they will be saved), and also identify some more principles for saving fixed files on the selected media.

Restoring damaged files with preview

If you decide "manually", without using the wizard, select the folder in the left part of the main window of the program in the left side of the main window in which files you need. On the right will display all the contents of the directory, and you can select the desired files in it.

If the file is damaged, the program will not be able to display its contents. To restore its structure, use the "File" menu - "Analysis" or "File" - "Study" of the main program menu. After performing these functions, the files will be available for preview.

Damage to important data on flash cards - the phenomenon is not rare and at the same time extremely unpleasant. We are accustomed to assume that flash cards are a more reliable tool for storing files than a computer or laptop, because they are often subject to breakage and loss of documents due to viruses and any other malicious software. However, flash cards are not protected from file loss, fortunately, they can be restored.

Before you know how to restore files from a damaged flash drive, first of all it should be understood that it causes this damage. Prevention is better than treatment, moreover, these knowledge will help you learn more about how to recover a damaged flash drive.

Causes of breakdowns and loss of files from a flash drive:

These reasons are the most common, but besides them there are other, less common, for example, blast furnaces. Numerous recording and reading cycles, download and removal can damage the flash drive. One way or another, you can not worry about this, since it is extremely difficult to use the drive to its wear. There are more serious factors that worsening the state of the flash drives, this is an elevated temperature and humidity.

Restore accidentally deleted or damaged files

Unlike the removal of documents from the desktop of the computer when you delete documents with flash cards, they do not fall into the basket, but are removed to be removed. You can restore such files using a special program to restore USB data.

Important! Remember what software Restores only deleted files that are not yet overwritten.

To understand this, you need to know how the flash drive works. When you delete the file, it is not erased from the drive itself, but it remains on it, but when you download new files, they occupy the place of previous ones. Therefore, if you accidentally deleted an important file, try to temporarily use a flash card to avoid overwriting.

The same method is also suitable for recovering data lost after quick formatting or after unsuccessful copying. Like removal, it does not erase the data, but only makes them possible for overwriting. Again - the sooner you will take the restoration, the more data you can.

Program	Description
Piriform Recuva.	The main advantage of this program is a lot of ways to use it. For users who feel that they need help in using software, there is a wizard that provides a guide to scan and recover.

Restoring files using Easeus

Step 1. Download and install the selected program, work with EASEUS will be considered as an example.

Note! Many of the programs presented above work in the same principle, so having familiarized with one of them, you will most likely cope with others.

Step 2. Select a location to start searching for data. Run Easeus Data Recovery Wizard, select the location where your data has been stored before deletion - on the flash card, and start scanning.

Step 3.. To start scanning, click on the SCAN Orange button.

Step 4. View and restore lost files. Easeus Data Recovery Wizard allows you to view files before recovery. Press the "Recover" button to restore the file, or "Cancel" to cancel the process, and close the preview window.

On a note! After previewing and filtering files, you can configure targeting to track files and click the Restore button to return all your files.

Restoring files damaged by viruses

Damage to files on the flash drive can be caused by worms or trojans. One of the common actions of a malicious software is to conceal files and folders, transform them into a small label that cannot be opened.

To restore files, you will need:

PC with Windows OS;
infected removable storage medium, i.e. USB drive;
antivirus program and / or software to remove malicious programs;
file search program;

Step 1. Check, hid your files or not. First, open the command line application through the search in the Start menu.

Then enter this command "ATTRIB -H -R -S / S / D F: *. * "Just as shown in the screenshot.

We enter the ATTRIB -H -R -S - S - D F- command in the field " Command line", Press" ENTER "

Important! This team implies that "F:" This is the name of your flash drive. Do not forget to replace "F" if the letter of the desired disk is different.

Now press the Enter key and check whether the files and folders are displayed on your disk. If so, then the problem is solved, if not, then go to the second step.

Step 2. Scanning and removing malicious programs.

Run Safety Safety. McAfee 2018 Antivirus, Kaspersky or any other antivirus installed on your computer are well fit. Open the program and do thorough check hard disk your PC and flash drives.

Now check the items on your device, see if labels disappeared. If yes, it's great. Otherwise it is possible that the virus or malicious software deleted your files. Go to step 3.

Step 3. Data recovery and disk formatting. First of all, you will have to format the USB flash drive, that is, "delete" all files. There is nothing terrible in this. After formatting, you can restore them in the same way as with random formatting, which was considered above.

Video - how to recover damaged files

In case of damage to the files, there is no need to immediately delete them, especially if they represent the value and there are no backups. First of all, you must restart the PC and re-open the file. At the same time, it is advisable to defragment the disk. If it does not open, then it is necessary to check whether the object expansion is correct. There are often cases when this is what the problem lies (this is especially true for novice users). In the event that the methods described above did not help, you can try to restore damaged files using the software.

Restoring graphic files

One of the most popular programs for recovering damaged graphic files is RS File Repair. With the help of the wizard built into the program, even a beginner can cope with her. The application is designed to restore files in JPEG formats (JPG, JPE, JFIF), TIFF, TIF, PNG. RS FILE REPAIR work is possible at all file systems and versions of Windows.

MSOFFICE file recovery

If it is impossible to restore the documents with standard MSOffice tools, the Easy Office Recovery program can come to the rescue. It pretty successfully restores the damaged and deleted documents of MSOFFICE: from MSOffice 95 and to recent versions. There is support for XLS, XLSX, DOC, DOCX, PPT, PPTX, PST formats. The wizard built into the program will make it quite easy to navigate in it and fulfill the task.

Restoration of archives

As you know, for transmission large number Files on the Internet and reduce the amount of stored information use archives. All this in the complex increases the popularity of their application, but at the same time the archives are very susceptible to damage. To restore them, you can use the means of the WinRAR program itself. In case of launching such an archive, a window appears in it, which reports that "the archive is damaged or has an unknown format."

To correct the archive, you must open the WinRAR program using it to find it and allocate. Then click the "Fix" button in the top menu. In the window that appears, select the directory for saving and the file type, then click OK. It remains to wait for the completion of the process.

In completion, it must be emphasized that best way Ensuring the safety of important files is to create their backup copies and saving on external media or online.
