Help with recovering deleted data from an Android phone. Recuva program: how to use, how to recover files, why the phone doesn’t see Recuva doesn’t see

Who among us hasn’t torn our hair out after rashly pressing the “Delete” button? Probably only those who have never dealt with a computer. Sometimes, months of work and tons of valuable files can go down the drain due to an incorrect finger movement. It’s good if you realized it right away - a program for recovering deleted files can help you..

How data recovery programs work

The fact is that, like nature, the computer file system does not tolerate emptiness. If you delete a file, then, as a rule, from file system Only the file header is deleted, that is, information about its location on the disk. The file appears to be there, but it is as if it is not there, since it is “without documents”. And, as long as nothing else is written over this file, it is possible to restore its rights. This is what they were created for special programs like Recuva, which we will consider further.

Installing Recuva

It is better to install this program before "lost loss" is discovered, since there is a possibility of installing the program on top of lost files. That is, it turns out that the doctor came and sat down on the patient’s sore. But, if the files are already lost (as usually happens), you can only pray that the program is not installed on them.

So, let's move on to the installation Recuva. Download the archive with the program from the official Piriform website

and extract the folder with the name Recuva. Go to the folder and run the Recuva.exe file. A window will appear asking you to select the program language. Russian is offered by default. If there are no objections, click “Ok”.

A window appears with a greeting from the program:

Click "I accept", confirming that we agree with license agreement(otherwise the program will not be installed). The next window will ask you to create icons for quick launch program and enable automatic checking for new versions:

Having selected the necessary checkboxes, click "Install". Once the installation is complete, a final window opens asking you to run the program after installation. Click "Ready", and here we have the recovery wizard:

Working through the recovery wizard

If you wish, you can skip it and go straight to manual recovery, but for the first time, it is still better to use its help. Click "Further" and the wizard asks what type of files are we looking for?

Let's say we're looking for lost photos. Choose "Images" and press "Further". A new window asking about the estimated location of the lost files:

As a rule, we remember exactly where they were (at least approximately). We indicate this place and click again "Further". Now the master is ready to begin the search, which he tells us:

Click "Begin", we observe the search process and as a result we obtain a list of found files. The output will be something like this (although, depending on the settings, it may also be in the form of a list, as in the photo below):

Here some of the pictures will be replaced by the inscription "Viewing unavailable". This means that some new information has already been written over them, and it will no longer be possible to restore them. To restore those that were saved, mark them with checkboxes and press the button "Restore" in the lower right corner of the window.

The Recovery Wizard will prompt you to specify the folder where you want to place the recovered files. We indicate the folder to it and click "OK". Now, if you open this folder in Explorer, you can find the recovered files there.

Advanced file recovery mode

Let's see what's hidden behind the button "Go to advanced mode":

Here we see a list of recovered files in the form of a table. In this window you can view the contents of each file (tab "View"), parameters (tab "Summary") and title.

From here you can start a new recovery session, specifying the same parameters that the wizard requested.

Recuva settings

Now let's press the button "Settings" and let's see what you can customize here. There is no point in describing them, the pictures speak for themselves.

The process of searching and restoring files is organized very simply, as is the program interface itself. Search results deleted files you can sort by type (graphics, music, documents, videos, archives) and immediately view the contents.

If you need to restore many files and at the same time preserve the folder structure, then you need to check this option in the settings.

To restore, select the files we need by checking the boxes and click on the button "Restore"

In addition to recovery, Recuva can also completely erase files so that they cannot be recovered by similar programs. To do this, you need to select a method for overwriting the magnetic surface of the disk on which the file(s) to be overwritten is located.

After selecting the method, you need to mark the files to be deleted and select the appropriate item in the context menu (right mouse button).

The program is actually quite simple and intuitive, you should not have any complications.

Sometimes people ask why the program was unable to recover some of the lost files? The point is that on hard drives Something is always erased and something is written down, some temporary files, some background Internet downloads, etc. AND, Since files on a disk are usually stored not in order, but in small fragments, the less free space on the disk and the more time has passed since deletion, the greater the likelihood that the necessary fragments will be overwritten by new ones. And the loss of any piece of a file is usually equivalent to the loss of the entire file. Therefore, small files are also much more likely to remain intact than large ones.

Do not install this program On the disk from which you want to recover deleted files, it can be written over the deleted files.

Modern smartphones and tablets are used to store information and process information no less frequently than computers. Accordingly, the problem of accidental data loss is no less relevant here: valuable photographs, videos, important documents - sometimes the loss is irreplaceable.

Just like when recovering lost data on a computer, the key to successfully recovering deleted files on Android is to exclude further writing to the media. Simply put, as soon as you discover that the files you need have been erased, you need to immediately remove the memory card or completely turn off your smartphone. These precautions help prevent memory cells from being overwritten.

Using a computer

The easiest way to recover files deleted on an Android device is from your computer. Special programs like Recuva or 7-Data will help you do this. Android Recovery. But to take advantage of their capabilities, you first need to enable USB debugging on your phone or tablet - this is necessary so that the device is recognized in the system as a removable drive.

Enable debugging:

If there is no "For Developers" section, follow these steps:

1. Open Settings.
2. Scroll down the menu to the About Phone section.
3. Find the item “Build number” and tap on it 7 times. As you click, a notification will appear telling you how many more times you need to click to become a developer.

After enabling debugging, the smartphone connected to the computer will be detected as external storage, from which you can recover almost any deleted data.

7-Data Android Recovery

7-Data Android Recovery, like Recuva, works without root rights, restoring files deleted from storage media. The only unpleasant thing is that you have to pay to use the 7-Data software.

Save the found data to your computer, not to your phone's memory. When the recovery is complete, simply transfer the files to your smartphone.

Recuva

The Recuva utility allows you to recover data from any media, incl. With microSD cards And internal memory smartphone. The procedure is no different from the recovery algorithm via 7-Data Android Recovery:

After scanning, you will receive a report of the data found that can be recovered. Next to each file there is a circle, the color of which you need to pay attention to:

• Green – information can be restored without problems.
• Yellow – file may be damaged.
• Red – data cannot be returned.

All you have to do is select the files and click “Recover” to get back the lost information.

The EaseUS Mobisaver and Undelete for Root Users programs work in a similar way, but they require root access to work, so it is better to first try to solve the problem using Recuva and 7-Data.

Using Applications

If it is not possible to recover files on Android via a PC, you will have to resort to using special applications. The main disadvantage of this method is the need to obtain root rights - without them, the application will not gain access to memory.

As an example, let's look at the Undeleter program, which can recover files from an external flash card and internal memory. Sorry, no purchase full version Only the image return function is available, but if you are satisfied with the application, then a small financial investment should not be a problem.

The application interface is friendly to novice users. You need to specify the folder in which the deleted data was stored, after which the memory scan will start. As a result, the program will issue a full report containing files that can be recovered from the phone.

It is often easier to prevent a problem than to deal with the consequences later. Removal important information is definitely one of those unpleasant situations that is best avoided. That's why:

Let's take the Dumpster application as an example. After installing it, you specify what types of files are sent to the Trash and how long they will be stored there. If necessary, you do the same as with the Recycle Bin on your computer - empty it or restore accidentally deleted files.

Surely every user has at least once encountered a situation when unnecessary file was deleted permanently, and later turned out to be necessary, or was erased accidentally - for example, during a system failure. What to do in such cases? One of the simplest and most accessible tools for recovering previously deleted files is the Recuva program, which is not at all difficult to use.

Recuva - what is the program and what is it for?

Recuva is a program for restoring permanently erased files from the British software developer Piriform, known to Russian users for the CCleaner and Defraggler utilities. It is produced in three versions:

• Standart - designed to work on PCs, laptops, netbooks and all-in-one computers;
• Portable - does not require installation on a computer, as it is used to work with removable media information.
• Professional - version with automatic updates, designed for in-depth recovery of damaged or lost files on PCs and virtual disks.

Standard and Portable are available for download for free. The Professional version costs 800 rubles. It is also sold as a set of four professional versions of the company’s products: , Defragler, Speccy and Recuva for 1,190 rubles.

Advantages and disadvantages

According to numerous ratings from ordinary users and professional magazines, this program has been the leader among utilities for recovering deleted files for several years now. However, like any program, it has its advantages and disadvantages.

The advantages of the product include:

• Russified, intuitive interface;
• availability of a fully functioning free version;
• interaction with any types of information storage devices - from hard drives to memory cards;
• the ability to manually select places to search for lost files;
• search for system and hidden files;
• the ability to restore the structure of previously erased folders and archives;
• work with most of the most common formats, types and types of information: text documents, tables, presentations, photographs, audio and video files, folders, archives, etc.;
• the ability to manually set the degree of depth for file recovery and the level of reliability of information deletion.

The disadvantages of the product include:

• duration of work - from several hours even with a simplified search;
• the ability to restore only those files whose condition was rated as excellent after data search - if their quality is average or worse, then they cannot be restored.

The program can recover different types of files, but only if they are erased in the standard way, by moving and then emptying the recycle bin or formatting the disk. If you previously used any other utility to permanently delete files, then Recuva will not be able to restore them.

How to use the program - features and functions

Recuva is a utility that every technology user will need at least once, since no one is immune from accidental file deletion or system failures. How to work with this program?

Installation

Interface and Features Overview

After launch, the program will automatically prompt you to select the type of files that need to be recovered. To improve the quality of your search, it is recommended to check the in-depth analysis box.

Upon completion of the search, the program will display a list of files that have been erased but can still be restored. The color of the circles next to the file name indicates the likelihood of success. Green ones have the maximum chances, red ones have the minimum ones.

You need to check the boxes for the files that you want to return from “oblivion” and click the corresponding button in the lower right corner.

To make selection easier, there is a “Summary” tab on the right side of the screen, which contains detailed information about erased files.

Please note that regardless of the type of drive from which data will be recovered, the procedure for using the program is the same.

What media does it work with?

In addition to hard drives on computers, laptops, netbooks and all-in-one PCs, Recuva can be used to check the following types of drives:

• memory cards;
• flash drives;
• digital players;
• smartphones;
• tablets;
• mobile phones;
• cameras;
• video cameras, etc.

This program will not be installed on any platform - for Android, for example, its analogue, Undeleter, is suitable.

Possible problems

Recuva is not only easy to install, but also easy to manage. It does not require additional knowledge. However, Recuva does not guarantee the recovery of any previously erased file, even if it was highlighted in green - this is its main problem. You can try to solve this difficulty using the Professional version or other utilities for recovering permanently deleted files.

The second common problem is that the program may not “see” the connected equipment: flash drive, phone, video camera, etc. First, it is recommended to disconnect the device from the computer and try to connect it again. If this does not help, you should update the device drivers. To do this, go to the “My Computer” tab, select the device, right-click on it and select “Properties”. Go to the equipment tab and click on the “Properties” button.

The inability to recover after secondary deletion is the only problem that cannot be solved. If files were erased from the drive and after that new information was written to it or some other files were deleted a second time, then the utility will not be able to restore the originally erased ones - it simply will not find them.

The Recuva program is not overloaded with unnecessary functionality and unnecessary details. Having installed it, even a child will be able to figure out how to use the wizard of this utility. It helps to quickly recover permanently deleted files from any storage media.

7 Data Android Recovery is on this moment The most popular program for data recovery on Android smartphones. However, it does not work correctly for all users. In some cases, the software is completely . What to do if the program does not want to work properly? In this guide, we will try to figure out why 7 Data Android Recovery does not see the phone and how you can fix this problem.

Causes of the problem and their solution

The program may not detect a smartphone or tablet computer for one of several reasons. It all depends on the type of device, the hardware used to connect it, as well as the operating system settings.

Below is a list of reasons why connection problems may occur and how to solve them:

1. USB debugging disabled

This is probably the most common problem. It's easy to solve, you just need to do it. To do this, you need to go to the settings of your Android phone and find the “For Developers” section there, it will have the “USB Debugging” item.



2. The smartphone is not put into standby mode

No matter how strange it may sound, in some cases, turning on the phone lock helps solve the problem with detection.

3. Drivers for connecting your smartphone are not updated

Outdated or uninstalled drivers for device identification in Windows system, may cause the 7 Data Android Recovery program to not work correctly. To try to fix the situation, download the latest version of drivers from the website of the smartphone/tablet manufacturer or update it yourself through the device manager.

4. Incorrect operation of the computer's USB driver

Check if all drivers on the system are updated to latest version. It often happens that in order to use some USB connectors on motherboard installation of an additional driver is required (for example, this often happens if the laptop uses the 3.0 standard).



5. Incorrect connection mode

Please note that the smartphone must be connected in storage mode, and not in modem or charging mode. In these modes, the program will not be able to see the SD card.



6. The phone is not rooted

Even if debugging mode is activated and disk drive mode is enabled, recovery is impossible without root rights (since by default the user cannot make changes to the file system). You can find out more about how to obtain these rights on your device on specialized forums.

In some cases, there may be problems with the USB cable, due to which any file transfer operations, as well as working with the device through programs on a PC, become impossible. The phone simply will not be visible to your PC. The only thing that will help is replacing the cable with a new one or connecting a memory card through a card reader.

Conclusion

In case everything possible reasons the problems described above are excluded, but the program still does not want to detect the device, perhaps it is not supported. In this case, you can try using more old version program or one of its analogues.

Recuva – free utility for file recovery from developers from the British company Piriform. Fully functional version programs can be downloaded for free, but there is also a paid edition of Recuva, which adds the function automatic update and support for recovery from virtual disk.
