How to download information from a damaged memory card. Data Card Recovery is a program for data recovery on sd and microsd. Free programs for data recovery from memory cards

Having problems with your SD memory card? Can't read all the data from it? Or does the phone not see them at all? You can try to recover a damaged SD card using a computer - check it for errors and completely format it.

Problems with SD memory cards are not uncommon. If a lot of data is recorded on it and you actively use it, for example, on your phone, then there is a possibility that after some time there may be problems reading the content. However, this does not mean that it can be immediately thrown into the trash.

There is always a chance to restore it. It does not always come to problems with the memory card controller - sometimes the solution may be, for example, checking for errors in saved files, repairing bad sectors, formatting, or completely clearing the partitions (structure) and creating them again. Consider the listed solutions.

What will be needed to restore the SD memory card

To perform data recovery from a memory card, you need to connect it to a computer. Therefore, we should have accordingly:

• computer or laptop with Windows system;
• an affordable option for connecting an SD card to a PC.

You can connect it to your computer in several ways. Can be done through the card reader built into the laptop. If not, you can purchase a USB card reader. In appearance, it is no different from a regular flash drive, with the only difference being that there is an additional input, into which we first insert a memory card, and only then we connect via USB to a computer.

Method #1: Repairing a Corrupted File System with Chkdsk

The first and easiest way is to use the system hard drive repair tool Chkdsk. This is a utility from Microsoft, that is, it is only available on a PC with a Windows operating system. Of course, this program is not always enough to recover data from SD cards, but you can check for damage in the file structure without losing data. In this method, we will restore the SD card through the command line.

To get started, insert the memory card directly into your laptop or PC and click on the "My Computer" or "This PC" icon (Windows 8 and above). In the list of disks, find the connected SD card and remember which letter was assigned to it. For example, let's assume that the letter "E:" is assigned to it.

Press the keyboard shortcut Windows + R to open the Run window. Type the following command to open Command Prompt:

In the Command Prompt window, you need to enter the appropriate command that will scan the drive and fix errors on it. The command looks like this:

chkdsk E: /f

Of course, instead of E: we enter the drive letter that your system assigned (not forgetting the colon). After pressing Enter, the scanning process will begin. Please note that the /f parameter is added at the end of the command, that is, Chkdsk not only finds problems, but also tries to repair them.

After scanning, we check the memory card again and see if it works properly.

Method #2: Format SD Card

In this method, we will try to restore the drive using formatting, during which all data will be deleted. This operation may solve the problem if repairing the memory card through Chkdsk did not bring a positive result and problems still occur (for example, errors in reading individual files). Of course, we will lose all the data, but there is a chance that restoring this way will prevent damage to new data that we will later copy to the SD drive.

Consider simple formatting that doesn't break the partition structure. Connect the memory card to the PC, and then open "My Computer" on the desktop. In the list of disks, find the SD card and right-click on it.
Select "Formatting" from the drop-down menu. Click on the Default Cluster Size button and make sure the file system is set to FAT32.

The operation can be performed with the "Quick Format" option. But for the best effect, we recommend unchecking this box - it will take more time, but it will be done more carefully and possibly solve the problem.

Once completed, reinsert the SD memory card into your phone, tablet, digital camera, or other device, and check if it now works properly.

Method #3: Deleting Partitions or Low-Level Formatting

An SD memory card is not much different from a regular disk - it can have one or more partitions. By default, there is always one partition. You can format the device in such a way that this partition will be completely removed and there will be unallocated space. This is the so-called low-level formatting.

Important! Like normal formatting, low-level formatting will delete all data from the SD card and there will be no way to restore files. Therefore, before restoring, copy to the PC the data or part of it that is still being read by the system.

On the unallocated space that will appear after formatting, you can create a new partition again. Very often it helps in a situation where, when an SD card is connected, it is displayed as “RAW” and partitions that can be entered are not shown. One of the best is the HDD Low Level Format Tool.

Connect the recoverable SD drive to your computer and run the HDD Low Level Format Tool. A list of installed hard drives will be displayed. Find the SD drive in it and mark it.

Make sure that the memory card is marked, and not, for example, the second or third hard drive on the computer. If in doubt, pay attention to the Capacity column, which displays the total capacity of this disk / flash drive or micro SD card.

After selecting, click on Continue and go to the "FORMAT THIS DEVICE" tab. The drive will be completely formatted, and the partitions will be deleted - only the unallocated area will remain. Exit SD card recovery software HDD Low Level Format Tool.

But that is not all. The SD card is not yet usable. Open the Start menu and search for Disk Management. Or type "Create and format hard disk partitions" in the search bar.

A window will appear in which all disks will be displayed - both installed on the PC and connected via USB. Find the connected SD memory card here, the bar of which will be highlighted in black.

Right-click on the black unallocated area and select Create New Volume." A partitioning wizard will appear on the screen to guide you step by step through the partitioning process. Pay attention to the "File System" field and make sure FAT32 is selected and not NTFS.

Confirm the creation of a new partition. This completes the SD recovery and now it will be displayed in the "My Computer" window with the drive letter automatically assigned. Then paste it into your phone or tablet.

Secure Digital Memory Cards(SD, SDHC) are designed for use with digital cameras and camcorders. Small dimensions, relatively high capacity and speed of operation; as well as the low price and absolute compatibility with almost any device made this type of memory card a leader in both consumer and professional devices.

Problems with SD memory cards

• Formatting, deleting files. The solution to the problem - in a few hours in the laboratory.
• Asks to format. It can speak of both a logical and a hardware malfunction. The solution to the problem - from several hours to several days. Most often - a day.
• Size 0 bytes. Hardware failure. Most often caused by damage to the translation of blocks due to the poor condition of the memory chips. It is solved by reading the memory on the programmer and assembling the image. 90% of memory cards are restored the next day after treatment.
• Not defined. Memory card hardware failure (controller failure). It can be caused both by damage to the memory card controller itself (or its "strapping" - voltage generators, matching devices), and memory chips. In the vast majority of cases, data can be recovered completely.

Restoring data from an SD memory card using an example
SDHC Transcend 16 Gb class 10

Condition upon admission to the laboratory: not detected by the camera or computer.

Inspection of the memory card: the case of the memory card is opened, there are two stickers with numbers from the services.

Diagnosis: memory card hardware failure (controller failure).

expert opinion: data can be restored within a day

Before entering the laboratory diagnostic procedures were carried out with the memory card, however, it was returned to the customer with the wording "can't do it due to lack of equipment". The laboratory "INTER" has all the necessary equipment for data recovery from memory cards of any configuration, including monolithic ones. This is one of the many reasons why you should go to a lab for data recovery, and not to the basement repair service for "any computers, laptops and phones."

Controller failure- the general name for all malfunctions of hardware origin in flash drives, the history of which begins with short-lived controllers and inexperienced specialists who made the "first diagnosis". In fact, almost all malfunctions of modern flash memory (both “controller malfunctions”, and “translation disturbances” and other fruits of the fantasies of specialists) are due to damage to the memory cells of NAND flash microcircuits.

During diagnostics it was found that the faulty SD card has two memory chips in the TSOP-48 package 29F62G08CBABA production Micron 8 GB each and controller SM2687BAA from Silicon Motion. To recover data from a memory card, it was decided to solder the chips and then read them. After soldering the microcircuits, their conclusions were cleaned of oxides: in the normal position, soldering of SMD components is carried out from below, and when installed in the programmer, the contact of the socket with NAND flash is made above, therefore, to prevent reading errors, all 48 pins are cleaned to a shine. To read the contents (dump files), the chips were installed in the data recovery complex from flash media PC-3000flash.

Memory Chip ID

The difference between memory chips of this type in terms of data recovery is that they use a slightly different power circuit than in older samples, in which it is necessary to supply additional 3.3 V power to 24, 34 and 38 pins (providing power to buffers ). PACK PC-3000flash allows not only to quickly change the configuration of the outputs, but also to change the value of the supply voltage. Reading memory chips was produced with a page size of 8944 bytes (this is the maximum size of the samples of flash drives encountered that fell into data recovery with such memory chips) - if necessary, the page size can be reduced to actually used by the firmware this controller. The remaining parameters for reading memory chips are taken from the reference book for NAND memory chips with id=0x2C64444B A9: SDR type, block size 4096 sectors. The timings at the first reading are left with a factor of 1, since there is no reason to believe that it is necessary to increase the duration of the pulses in this case.

After reading the memory chips for this type of SD card controller, you must immediately do ECC correction, since it makes no sense to restore data from uncorrected memory dumps: all restored photos will turn out to be “broken”. Additionally, according to the ECC status map you can judge the health of the memory chips and try to subtract information that matches the content as closely as possible. In this case, the ECC code corrects the page in the following way: an ECC code of 70 bytes in size protects 1024 bytes (two sectors) of user data and itself, with 8 such ranges, and after them another 26 bytes of service information with ECC. After the ECC correction, we received information about the areas that cannot be adjusted due to the ECC code - sections containing damaged(worn out) memory cells, and for the first microcircuit, the size of these sections is a little more than 1 GB, for the second - almost half. It makes no sense to restore data from dumps with such severe damage, since bit errors that occur when reading bad cells modify information in such a way that instead of useful data, garbage appears in the results, and this garbage can also occur in the service information area.

Service Information Areas– ranges of NAND-memory pages that do not contain user data, but contain service data: ECC codes, translation tables, block markers, etc.

Uncorrected pages.

To reduce the amount unadjusted pages, the method of reading uncorrected pages with ECC control and using various algorithms (the Read Retry algorithm, increasing the pulse repetition periods - timings, increasing / decreasing the temperature and supply voltages) is used. In this case, the algorithm Read Retry, which consists in changing the internal parameters of the memory array by external commands, developed specifically for data recovery stored in such memory chips. Rereading process with ECC control- one of the longest processes when recovering data from flash cards running on heavily worn TLC memory, sometimes lasting several days. As a result, we have memory chip dump files corrected by more than 99%, which will allow us to collect a reliable image and restore all data with virtually no loss. The result of the reread can be seen on the map of uncorrected pages: in this case, each dump contains no more than 10 KB of uncorrected sections.

Some data recovery systems (and the people who work on them) are not capable of ECC rereading with the Read Retry mechanism. In such complexes, these microcircuits are called Problem chips and cannot be restored.

Considering the fact that almost all controllers SM use XOR transformation in their work to recover data from a memory card before eliminating the so-called "mix"(mixing data between parts of the memory chip and individual chips), it is necessary to choose a mask with which modulo 2 addition (XOR) is performed. Mask applicable to this memory chipset and controller XOR 247(from the XOR library of the complex) with dimensions (1024+70)*8+26, which in total will give a page size of 8778 bytes. Since the page size with which we read the microcircuit is larger than the XOR mask, we will not lose data, but the page will have to be “cut” a little, however, this will pass absolutely “painlessly”, because unused areas in the pages are filled with the number 0xff. For the convenience of the complex, we will choose a slightly larger required page size, multiple of 0x10(or 16 in decimal): 8832 bytes, of which we use 8778 for XOR conversion, and just leave the rest as a "stub". After applying the XOR mask in the dumps, you can find headlines files and pieces of the file system, but the size of these fragments will not exceed 1024 bytes due to the fact that the useful data is still mixed with service data. For branch custom data from ECC codes and service information apply the "page designer" method, with which we cut out the used ECC codes, divide the ranges into sectors and indicate service information for each sector.

Preconversions

Sector– minimum unit of disk space addressing. Flash drives, like most media, have a sector size of 512 bytes. However, for data recovery, the sector size used in the complex is 512+SA (said area size). For ease of calculation, an SA size of 16 bytes is often used, even if the actual size is smaller.

In our case, the size of the service area corresponding to each sector is 26 bytes (this value is determined by the manufacturer at the production stage of the memory card), so we “discard” the part of the page that contains error correction codes and assign 26 bytes of service information to each sector of the page . As a result, we get a page “cut” as follows: ((1024 bytes of user data in a row)) -70 bytes of ECC code) * 8, and after them 26 bytes of service information follow (which in the editor will be “glued” to each sector ) and “stub” (appointment - see above). One of the reasons why to recover data from a memory card it is forbidden just subtract the contents of the chips with a programmer (even if there is no XOR conversion, which is a rarity for modern media) and scan with a program like R-Studio and the like, just that there is useful information inside the memory chips mixed up with a service one and in this example, it would not be possible to get a fragment of a file larger than 1024 bytes.

Small file fragments

At data recovery from memory cards(and any devices with NAND-flash memory) it should be remembered that all transformations can be conditionally divided into two stages: elimination of mixing in blocks and assembly of blocks in order of priority. Primary Conversions(the so-called "mix") depend not only on the controller firmware, but also on the device directly on the memory chips. So, looking into the directory of memory chips, we will see that chips with id = 0x2C64444B A9 can have more than one plane inside the physical part. In practice data recovery this feature manifests itself in the form of fragmented data the size of an interleaving block (the size of a block written in a row in one plane). By analogy with, this feature represents blocks that were originally located on different drives, placed one after the other. The presence of such mixing can be checked by the method "rough restoration" in PC-3000flash: running the method on any dump, we will see that the maximum checked file size is too small to build blocks, which tells us that there are some transformations (in our case - Interleave). The characteristic interleaving is eliminated by the method block pair: we divide the dumps into blocks of the same size (the size of an interleave block) and combine them in pairs, thus “gluing” the blocks that followed one after another, but were written in different planes.

Given the presence in the SD memory card two chips(and, accordingly, two files - dumps), it is necessary to determine relationship between them: in any case, there is another similarity RAID, or RAID0 or JBOD (depending on controller firmware settings). To check the type of relationship between memory chips, we use the view service information for a pair of sectors located in different dumps at the same address. Keeping in mind that for SM controllers characteristically position at 514 and 515 token bytes with block number, we conclude that information from one block is located in different memory chips - just like in RAID0. To eliminate this transformation, let's merge the "semi-blocks" located in the dumps in pairs, and on the resulting merged dump, we will start the "rough" recovery. The appearance in the results of "draft" files with a verified size of more than 1 MB indicates that all transformations inside the blocks have been performed correctly and you can start building the blocks in sequence (assembling the image).

Comparison of service information of memory dumps

final stage when recovering data from a memory card, image assembly(translator), which involves building blocks in order and distributing them among banks (blocks with the same numbers must fall into different banks and follow with a period that is a multiple of the bank size). Given the presence in the service area of ​​pairs of bytes with the block number, you can try to apply translation algorithm"Block number 0000".

Build image by block number

Master Boot Record

Image builder settings

Analyzing service information recoverable memory card, we determine that during assembly it would be logical to highlight the sequence 514 and 515 bytes for numbering block, however, the service information of the first (in computer numbering - zero) block will contain a pair 00 08 , second ( first by computer) 01 08 etc. that not quite right: firstly, the older part of the number comes before the younger one, and secondly, the older one starts from 08, not from 00. solved this problem is quite simple: in the settings of the assembler algorithm "unfold" marker (marker type 3412) and "move" it (mask 70FF). Block size for the assembler, we calculate according to the advanced methodology of the second grade of high school: the size of the block of the memory chip (reference value, equal to 4096 sectors) is multiplied by 4 (this number is due to the transformations performed) and we get 16384 . We start the collector, look at the log and expect to see the root directory, data, etc. But it was not there: root directory is empty, the data is not visible. We start the “draft”, we see the following picture: a lot whole files (which means that the conversions are correct), the MBR is set in place, which means that the collector parameters are also defined correctly.

Whole files

Probably a build issue. It is worth noting that markers for the assembler, these are by no means reference points for the operation of the controller, but pieces of debug information, they may not be contained in all blocks or not contained at all. Therefore, let's try to apply a different assembly algorithm (specialized translator).

Assembly EN2683B BA

Algorithm selection

Complex for data recovery from memory cards PC-3000flash is able to determine the type of block translator (assembler) by indirect signs(structure of service information). Often assembly according to translation tables (translator application) gives a much more complete result, since almost completely simulates the algorithm of the controller. Automatic selection (algorithm auto-detection) offered a translator for our memory card EN2683B, so we apply this translator with autodetection its operating parameters. As a result, we have the result similar to the first collector: no file system, but whole files. I.e the problem is not in the parameters and hardly in the type of translator. Of course, it could be on this stay, to tell the customer "the microcircuits are badly damaged, they did everything they could, but they can no longer be restored", but this not in our rules We will look into the reasons.

Filling in missing blocks

Analyzing service information the resulting image and see that in the image do not fall some blocks (filled with a characteristic pattern DEAD). Cause lies, as is often the case in the data recovery industry, in the device and how a memory card works. Many modern controllers for speed up work(and for multimedia storage media, speed is one of the most important characteristics) blocks are used different size(almost like ZFS), for rarely changing data (user files directly) – big blocks, for often changing data (file system elements) – small blocks (or additions) that cannot be processed by some assemblers (for example, those discussed above) and it is impossible to get a complete file system. Absence working file system will cause not only the absence titles for files (which, in general, is not particularly critical for photos from the folder DCIM), but also by the absence in the image large and fragmented files(for example, videos).

Assembly EN2685

From libraries of additional methods choose a specialized algorithm designed for data recovery from memory cards for cameras with controllers that use in their work additions. The operation parameters of this translator are calculated at the stage of elimination of transformations: block size 16384 sectors, the size of additions is determined at the last step of transformations by changing markers in pages containing elements of the file system ( 32 sectors). Having assembled the memory card image using a translator with the necessary parameters, we get access to user data: in the root directory of the DCIM folder (with a green mark that indicates that the folder header is correct) and the files inside.

Root directory

Recovered data

Memory card data restored the next day after applying. Take care of your nerves and money: contact professionals who will take care of all your worries. Avoid contacting those who see the difference between NAND and BGA chips, offer data recovery with a price per megabyte, as well as field craftsmen and home craftsmen.

The holiday season is coming soon and, accordingly, everyone will want to leave a dozen or two pictures or videos as a keepsake. But no one is immune from accidental loss of memory cards from photo and video devices. Even the most important information, no matter how carefully you store it, tends to get lost. For various reasons. Methods for recovering files from memory cards will be discussed.

Causes of data loss from memory cards

1. Crash in the file system;
2. Drive controller failure;
3. Mechanical damage;
4. Removing the memory card while the device is running;
5. Accidental deletion of the wrong files.

The highest probability of complete data recovery will be only if you did not write information over the lost files. Do not rush to insert a memory card into all kinds of devices for reading information.

Ways to recover files from memory cards

Nowadays, there are a huge number of different devices for storing data, but I would like to pay attention to memory cards. Most devices use the following cards:

1. SD, SDHC
2. Micro CD, Mini CD
3. compact flash
4. Sony MS.

Many cards are restored like USB sticks. At home, it is almost impossible to recover information on Micro CD cards. Even if your camera fell into water, you can restore some of the files yourself, but immediately after removing the device from the water, be sure to dry the memory card and wipe it with alcohol. Do not overwrite data that needs to be recovered. If your card has everything in order with the electrical circuit, then try to immediately create an image of the card.

Free programs for data recovery from memory cards.

Let's focus on the simplest program from the user's point of view. Recuva is the brainchild of Piriform and the sister of CCleaner, you can learn more about it.

So, after you have downloaded the Recuva program, run it and connect your memory card to your computer through a camera or card reader, and if the computer does not see your memory card, read. Then select the type of files you need to recover :( Other- universal version).

And we see a window with the inscription " Thanks, Recuva is ready to start searching for deleted files." Below, check the box " Enable in-depth file analysis" and then press the button To begin«.

In the next window, the program will require you to select files to restore. The preliminary result is marked according to the traffic light principle (red - it cannot be restored correctly, yellow - you can try, green - it will be restored in the highest possible quality). After selecting the desired files, feel free to press the button "Reestablish".

And finally, you can choose a location on the disk (just not on the one from which the files were restored!) To save the recovery results.

If you decide to recover data with your own hands, then the main thing is not to panic and be 100% confident in your abilities, otherwise it is better to turn to professionals for help. Remember that it is easy to find utilities from the manufacturers of your particular memory card on the Internet, the only question is how badly your card was damaged. Do not forget that each memory card has its own physical resource, after which the card cannot be restored.

Often there is an urgent need to return photos erased by mistake. Data is stored on a compact memory card or USB flash drive, and for some reason we treat these storage devices irresponsibly, which we later regret very much.

Since such questions often come to the site, we will share one of the recipes on how to recover deleted files from a memory card. By the way, if after reading the material you still have incomprehensible moments, ask us your questions.

What is a memory card? This is a type of removable flash memory created by Sony in 1998. When designing the storage device, it was taken into account that the memory should not only be convenient for storing multimedia information, but also for sharing and universal storage on devices other than digital cameras. Lightweight, easy to use, the memory card contained photos, documents, music, pictures and more. The original size of the flash drive was about 128 megabytes. In 2006, the memory called Las Vegas ICES was introduced, it contained 8 GB of data.

The process of recovering photos on a memory card: step by step instructions

1. Download MiniTool Power Data Recovery

A memory card can store many photos and videos. They can just as suddenly disappear. Information can be returned, as is the case with other media - flash drives, hard drives.

For recovery on the sd card, it is recommended to download MiniTool Power Data Recovery. The program is suitable for recovering photos, images, pictures from a memory card. It takes up little space, is easy to use, and incorporates the latest technology to search and scan the surface of a memory card.

Limitations of Power Data Recovery. The free version of Power Data Recovery (Free Edition) allows you to recover up to 1 GB of any data. This is usually enough to restore favorite photos from a phone memory card or microSD camera.

Status bar displays recovery limits

2. Choose the appropriate media file recovery module

After launching MiniTool Power Data Recovery, five recovery modules are available in the main window:

1. Undelete Recovery (recovery of deleted files),
2. Damaged Partition Recovery (recovery of damaged partitions),
3. Lost Partition Recovery (reconstruction of deleted partitions),
4. Digital Media Recovery (recovery of multimedia data),
5. CD / DVD Recovery (removable media).

Selecting a recovery module in MiniTool Power Data Recovery

Each module is documented in detail: the help tells you how to work with a particular type of recovery.

For our needs, the type of recovery Digital Media Recovery is suitable, and we select it.

3. Specify a memory card / USB flash drive for recovery

In the list of disks and partitions, specify the memory card from which the recovery is performed. In this case, the storage device must be connected to the computer.

Connection via card reader

If you are dealing with a memory card, you need to connect it to the PC via a card reader and a USB cable. (Some laptops and Macbooks have a built-in card reader.)

Selecting a storage device / partition to scan

4. Specify the required file types for recovery

In the advanced settings (Settings button), available at the bottom of the Power Data Recovery window, there is a filter by data type. It helps to save time: for this you need to specify the necessary extensions of multimedia files (photo, video, etc.)

Limiting file types for searching on a memory card

In advanced settings - seven options to choose from: Documents, Archives, images / photos, email, databases and other information. Specify the file types Graphics & Picture (Images and pictures).

By clicking on the cross to the left of the file type, a narrower filter is available. There are many image formats here: dwg, psd, cdr, jpg, gif, png, bmp, etc. Again, you can only specify the required photo formats (most often raw / jpg) and click OK to confirm.

5. Scan the memory card

We are back to the main application window. Press the orange Full Scan button to start. In the window that opens, the process of searching for photos and the number of files found will be displayed.

Progress bar with information about found files

6. Save recovered photos to disk

In the sidebar in the Path tab there are five folders containing pictures in various formats.

MiniTool Power Data Recovery has a special filter that displays only the desired and available data types. You can set the filter through the settings (Settings button at the bottom of the Power Data Recovery window).

Preview and save found deleted photos

Select the recovered photos by checking their boxes and click the "Save Files" button.

Specify the save source and click OK.

Important: do not save the found photos on the memory card! It is better to specify any disk on the computer with enough free space. Otherwise, the data will be overwritten and, as a result, you will not be able to restore the files again during a subsequent search.

bottom line

We have described the process of recovering photos from a memory card using MiniTool Power Data Recovery. If you repeat the steps described in the instructions, you may be able to get back the deleted photos. If not, try another memory card image recovery software like Photorec. Here on this topic.

Question answer

1. Samsung S4 phone. Yesterday the photos disappeared from the memory card. At the same time, the rest of the information and videos remained, several photo recovery programs found a lot of photos, but among them were only those that I deleted manually. And those that are missing are not. How to recover deleted files from a memory card, is there anything else I can try to do? The phone saves new photos properly.

2. When copying files from the sd card, the laptop rebooted. As a result, the photo is neither on the memory card nor on the laptop. What to do? Help, dear, to recover data from the sd card! There are all the photos of the first year of my child! I'm desperate.

Answer. Try to recover files using Power Data Recovery according to this guide. If the photos are still not found, try the free PhotoRec or Recuva apps with the deep scan option.

By the way, it is not always possible to restore old media files. If a lot of time has passed and the files have been overwritten, the chances of recovering anything are significantly reduced.

I have a Philips phone. I got into the Gallery - it turned out that all the photos that I took with my phone were gone. He pulled out the card, inserted it into the laptop - the folder was also empty. Is it possible to recover photos from a memory card?

Answer. If the photos were really stored on the memory card, the chances of getting the data back remain. The main thing is not to use a memory card on your phone / laptop. Connect it via a card reader and start recovery immediately. Power Data Recovery allows you to save up to 1 GB of photos: others, such as PhotoRec, are not limited.

The sd card broke in half. Is it possible to restore photos from an SD card on an htc desire 620g phone, and if so, how?

Answer. Unfortunately, you will not be able to restore a photo after such a breakdown, even if you glue the memory card piece by piece. Such repair is impossible in principle, even the manufacturer of the card will not help in any way.

1. Phone Samsung J5 2016, flash drive (memory card) 32 GB is used for 4 months. The photos on the memory card began to deteriorate: half of the photo is gray or all gray (not all photos). I tried formatting - they still turn gray, but not all photos. Please tell me what to do?

2. On the Samsung Galaxy Tab E tablet, all data has disappeared from the flash drive. Android writes: "the memory card is empty or has an unsupported file system." What should I do and is it possible to somehow restore these photos, videos and applications?

Answer.

1. Check the memory card for errors.
2. Update your smartphone firmware and uninstall unnecessary applications.
3. Check your mobile device for viruses.

I dropped my phone in water. I immediately dried it and left it. Two days later I turned it on and all the data (photos and music) just disappeared. Help me please. I have a Samsung Galaxy Grand 2 SM g7102 phone. (The SD card worked for 3 years without error.)

Answer. Check if the memory card is detected by the mobile device. If not, try it.

Also remember if the files were on the memory card or still in the internal memory of the device. Based on this, restore photos.

Why is information lost from the drive?

Before moving on to the process of recovering data from a memory card, you should analyze the main causes of such a problem, as well as in what cases recovery is possible.

Types of problems with the card:

1. the user accidentally deleted the necessary files;
2. formatting has been done.
3. the card was removed from the device during operation, which caused damage to the logical data structure;
4. The SD drive is full, so the computer cannot recognize it;
5. there was a failure in the electronics, which led to the burnout of the card controller;
6. the drive has been mechanically damaged.

In the first four cases, photo recovery from a memory card can be done independently using special software. To eliminate the last two faults, one cannot do without knowledge in electronics, since it is necessary to carry out physical intervention in the card microcircuits. In this case, it is possible that mechanical damage to the drive can lead to a complete irretrievable loss of data.

Programs for recovering photos from a memory card

There are a large number of utilities, both paid and free, that specialize in recovering data from an SD card. Here is a list of the most popular ones:

1. R-Studio;
2. CardRecovery;
3. Active File Recovery;
4. Recuva.

You can select and download a data recovery program.

The CardRecovery utility deserves special attention, as it specializes specifically in recovering photo and video files from memory cards and flash drives, and is also easy to use. The only negative is that the program is paid.
