SD card (Secure Digital Memory Card) is one of the most popular devices for storing information. It is compact and can hold tens of gigabytes of information. Most mobile devices store data on MiniSD and MicroSD.
Unfortunately, SD cards are not protected against loss of photos, videos and documents. Scenarios for deleting files on an SD card are varied. This includes erroneous formatting, damage as a result of unsafe removal from a card reader or phone, and accidental deletion of files and folders. Basically, users of Android mobile devices lose videos and photos from the Gallery, and less often, documents (text notes). This review presents best tools to recover data from SD cards.
Review participants:
7-Data Card Recovery - a program for recovering information on sd and microsd
7-Data Card Recovery is included in the 7-Data Recovery Suite. It will help those users who have lost files on the SD card as a result of formatting or unintentional deletion. All standard are supported file formats Android for audio, video, images. Considering the features of Android, the list is not so wide, but this is more than enough for an SD card recovery program.
7-Data Card Recovery recovers data only from external memory mobile device. The most popular types of cards are SD Card, SDHC, Compact Flash, xD Picture Card, MicroSD, Memory Stick.
The 7-Data Card Recovery application is installed on a computer running Windows XP >. To search and restore a microsd, you need to connect it to your computer via a card reader. After connecting, a list of removable storage devices will be displayed; you need to select an SD card from the list. By the way, the program also works with local disks, so the scope of this tool is much wider than it seems at first glance.
The cost of a 7-Data Card Recovery license is $49.95 (home edition), a yearly subscription is $39.95. The trial version can be downloaded for free.
Note. In addition to Card Recovery, an Android Data Recovery edition is available. She works with internal memory tablets and smartphones. The program is compatible with popular mobile brands like Google, Samsung, Lenovo, Fly and others.
Card Recovery is a highly specialized program for recovering photos and videos on an SD memory card
Although there are dozens of programs for recovery from memory cards and flash drives, not many can boast of a good track record and real, not marketing, recovery functions. The CardRecovery program is considered a “veteran” in the recovery application market. If you examine the list of deletion scenarios, user cases, supported cards, digital camera manufacturers and file types- in general, it becomes clear that this is a professional tool for SD resuscitation.
The latest version of CardRecovery is v6.10. The product has not been updated for quite a long time, yet it works without problems under Windows 10 and reads all known types of SD memory and connected removable devices. Generally speaking, Card Recovery specializes in data recovery from SD cards of digital cameras, phones, tablets. The main types of data are video and photo. If you need to recover files from hard drive or specify specific file formats to search, it is best to refer to other products.
The key feature of CardRecovery is the SmartScan function, thanks to which you can find photos and videos by signatures. This can be especially useful if the SD card's file table has been destroyed after formatting or corruption. There is a deep search function in Recuva program, but CardRecovery performs a quick analysis of multimedia formats.
Disk Drill is a recovery program with a simple interface and wide support for storage devices
DMDE – professional recovery from memory cards, flash drives and HDDs
We included this program in the review, despite the fact that the free version is limited. DMDE is used in professional circles as a convenient and effective recovery tool. The program is cross-platform - you can use it under Windows, Linux, Mac OS and DOS - via the command line.
Let's talk about the restrictions right away. The free version of DMDE allows you to recover up to 4000 items.
Other versions of the DMDE program (Express, Standard, Professional) remove the restriction on the file limit, the license cost starts from €16.
In addition, basic tools are available in the free edition:
- Disk editor - allows you to manually change the disk structure, file tables deep search deleted files,
- Creating a disk image for subsequent recovery from a complete copy of the original.
The list of compatible storage devices includes HDDs, RAID arrays, usb flash drives, sd and microsd cards. File system – almost any of the known ones. As a rule, for memory cards we are talking about NTFS, exFat or FAT. Linux and Mac OS FS are also supported.
Which SD card recovery program should I choose?
- Recuva is a free recovery application that works fully without paying (we hope it will always be this way). Therefore, this program is the most popular on the market.
- EaseUS Data Recovery Wizard in free version limited to 2 GB of recoverable information - which is quite enough at first. The program is convenient and contains a step-by-step wizard.
- 7-Data Recovery and DiskDrill are now the same program. It has some nice additions like pausing scanning and searching by signatures.
- Glary Undelete – quite simple program. It is quite suitable for restoring files on a memory card, but it lags behind all those listed in terms of functionality.
- DMDE is perhaps the best professional tool, the price is low for such a list of features. It fully searches for files on a memory card, although for the most part it is used to recover data on a hard drive.
- Photorec is best for finding lost photos and recovering them on any desktop platform. Memory cards, as stated, are supported; you can work with them through a card reader.
It's no secret that quite often many users mobile devices are faced with the problem of failures when the memory card in the device is not detected or the data on it is either damaged or destroyed for some reason. This is where the search for a solution to how to restore the memory of a memory card begins. At the same time, naturally, everyone wants not only the card to work, but also the files to remain on it. Doing this is not as difficult as it might seem at first glance.
Why does the memory card malfunction?
Unfortunately, there can be many reasons for failures in the operation of removable memory cards of any type. Not to mention some incorrect actions of the user himself, such as accidentally deleting data, there may also be physical damage to the card, normal wear and tear after the end of its service life, and even problems in the operation of the control microcontroller.
And how to restore the memory of a memory card? For any variant of the problem, you can find universal solutions using either hardware or software methods.
Is it possible to recover a memory card?
In general, you should clearly distinguish between situations when you only need to restore files or when you need to restore the functionality of the card. These are two different things. Accordingly, the solution to the question of how to restore a memory card on a phone will be different in each case.
Software method involving the use special programs, is simpler compared to hardware when malfunctions occur in the microcontroller. Nevertheless, we will begin to consider the problem with the second method, since without identifying the card on a computer or laptop, there is no need to talk about any data recovery.
The memory card is damaged: how to restore its functionality?
So, we assume that the microcontroller has “flyed”. In this case, you can forget about data recovery, since the card will have to be formatted.
Please note that special firmware from the card manufacturer must be used for this. There is no other way to do this. When a card is connected to a computer or laptop via an adapter (card reader), in the best case, the system writes that there is no space on the removable disk, or the disk space is defined as zero. In the worst case, the memory card is not recognized at all.
The easiest option when solving the question “how to restore” is to use regedit called by the command through the “Run” menu, where in the HKLM section go to the SYSTEM subsection, and then through the key tree find the StorageDevicePolicies directory. On the right in the window you need to set the zero parameter (usually 0x00000000( 0)). But this does not provide a 100% guarantee that the card will work.
How can I restore the memory of a memory card? You need to use the hardware identifier (PID) value and the vendor identifier (VID) value, and also take into account the Chip Vendor value (although in most cases you can do without it).
These values can be found on the chip itself, but the card will have to be opened. In principle, if the card is detected by the system, you can use utilities like CheckUDisk or USBIDCheck.
Now, using this information, you should find the controller’s personal firmware on the Internet and download it. If the search is difficult, you can use online services like iFlash, where you can use the data you enter to find the program you are interested in. Next, using the downloaded software, we simply format the card. Please note that each such memory card recovery program is universal and is intended exclusively for one model or one device manufacturer.
The simplest data recovery program Recuva
Now let’s assume that the card is detected by the computer and works without problems, but the required data on it is damaged or missing. Recover data from a memory card in the most in a simple way you can use the well-known Recuva utility.
After launching the application, select recovery either by file type, or check the “Other” option (to search for all content), and then specify the source (memory card). Next, we enable the in-depth analysis option and begin the scanning process.
At the end of the process, the result will be displayed. Red indicates data that cannot be restored, yellow indicates data that you can try to recover, and green indicates data that can be restored without problems. It’s probably already clear that you can only restore files on a memory card that are marked in yellow and green. True, for dubious data positive result not guaranteed.
R-Studio package
R-Studio package is more powerful utility. It allows you to recover data from a memory card even if the files themselves are quite damaged, file system or even device memory sectors.
After starting the program, select the media you are looking for and press the start scanning button. In the pop-up window that appears, you can set the data type, size of the scan area, etc. The results will show all physical and virtual partitions of this device with the files present on it and boot records. If the partition has been formatted, it will be highlighted yellow. Now all that remains is to select the desired directories or files, and then save them in any other location on the computer. As is already clear, in the future the information can be transferred to removable media without problems.
Auslogic File Recovery Application
Another quite interesting program for recovering a memory card (meaning the information part) is the Auslogic File Recovery utility.
Its main difference from R-Studio is that it has, so to speak, a simpler and friendlier interface, although it is paid. However, the application has a convenient search system and preview of scan results. And this, in turn, helps to restore only what is really necessary.
Hetman Uneraser program
A fairly simple, but no less interesting utility can be called the Hetman UnEraser package, which few people know about.
The application interface is very similar to appearance standard Windows Explorer. Deep scanning even with damaged file systems or partitions is carried out automatically. At the same time, removable cards of any type are supported, including those used in photo or video cameras.
SoftPerfect File Recovery utility
The small SoftPerfect File Recovery program is most suitable for inexperienced users in cases of minor non-critical failures. If formatting has been done, unfortunately, the utility turns out to be useless.
On the other hand, it is not without a number of advantages. First of all, this is the ability to work with compressed volumes and partitions. In addition, it is distributed completely free of charge and has no restrictions on the period of use. But this, as they say, is a last resort - to quickly eliminate minor troubles.
Magic Uneraser program
But the Magic Uneraser application, unfortunately also little-known to users, has quite interesting opportunities. The search and recovery algorithms are almost the same as those of the programs described above, but the advantages are obvious.
First of all, it is worth noting that the program is able to find even those files that other utilities miss, it allows you to restore files and folders while preserving names and metadata, but most importantly, the application can immediately package the recovered information into ISO images, which can then be used when recording to any removable media.
Conclusion
Here we briefly looked at the problem of how to restore the memory of a memory card. Naturally, it is simply impossible to describe all programs designed for these purposes, so the main attention was paid to the most powerful and popular utilities.
But here it is worth paying attention to the fact that they should be used only if the cards themselves are working. If there is a problem with removable media is that it is not detected or has zero volume, you will have to first restore its memory. But then you can use some of the utilities described above (in particular, R-Studio), which allow you to restore any type of data even after formatting, because the information you are looking for does not go anywhere, it is simply overwritten in memory sectors, and the name of the initial file with the assignment changes to him at the beginning of the name of specific unreadable characters.
Read, how to fix a memory card and recover data from it(regardless of the card manufacturer and model), and about the reasons for card failure. Losing images or crashing a memory card containing important photos makes you feel lost forever? Or have you already had the bitter experience of losing important data due to a damaged SD memory card? In our article we will look at the answers to these questions and show how to repair a memory card and recover data from it, regardless of the reason for its failure.

Introduction
Personal electronic computing devices are an integral part of the control mechanism information flow and are used daily in various industries. Their use makes it much easier for users to perform their business duties, process and store various information, create and exchange various projects, and these devices are also actively used for recreation and entertainment.
Personal desktop computers and laptops are widely used and are rightfully the most popular among other devices. Such successes were achieved largely due to the combination of characteristics of computer devices, firmly securing their leading position: ultra-fast processors and components random access memory, data storage of the maximum volume, instantaneous information processing speed, a high degree of device unification, multitasking, which allows you to solve a complex of different tasks without reducing the performance of the device, and overall high performance in general.
The main responsibility for managing, storing, processing and exchanging information is assigned to a specialized software, which should take full advantage of the computer's maximum capabilities, and have attractive and convenient functionality. The operating system is a leader in its field and fully complies with these conditions. "Windows", developed by the corporation "Microsoft". With a user-friendly interface and the highest speed capabilities, it easily copes with any kind of tasks that end users encounter in the course of their activities.
A separate type of computer device, which, especially in Lately, have become extremely widespread, are mobile smartphones and communicators. The catalyst for its extraordinary popularity was the creation and widespread dissemination of international information computer network "Internet". Possessing noticeably smaller internal characteristics and offered capabilities, they achieve recognition due to high mobility and a variety of communication methods available to users with their help: mobile communications, instantaneous text messages, video communication applications, access to social networks and other online communication platforms "Internet", messages by e-mail etc.
A separate element that has contributed to the increase in the popularity of smartphones is the ability to use them to create high-quality photographs and videos. Personal archive, instant photos for memory, pictures for sharing in social networks, funny videos and much more can be easily done with smartphones, especially since users always carry them with them. If it is necessary to capture high-quality photographs, professional high-resolution cameras are used, which, due to high competition between manufacturers and applications the latest developments, have significantly decreased in cost, and are freely available to every user for daily use.
Due to the fact that the volume of photographs is growing daily, and they were taken in high resolution, the internal memory capacity of the devices is insufficient to store them, and additional storage is required. In such cases, the main storage device for user data is memory cards. various formats. Having low cost and significant internal capacity, memory cards are widely used. The most common of them is rightfully considered "SD" memory card.
However, like any computer device, a memory card is subject to various influences and can be damaged by various reasons. Next we will look at possible reasons damage to memory cards and we will suggest ways to restore the information stored on them.
Memory card "SD"(English) "Secure Digital Memory Card") is a miniature storage device designed for repeated recording, storage and reading of various digital information. The main place of its application are portable electronic devices: mobile smartphones, digital cameras, e-books, "GPS navigators", some types of game consoles, etc.
The card has standard size 24×32×2.1 mm, which allows it to have its own controller and a special area, directly memory chips responsible for recording and storing user data, the operating principle of which is implemented using flash memory (a special reprogrammable semiconductor technology).
As development has progressed, the internal capacity of flash memory has changed, and today, it is available in sizes up to "128 TB". Memory cards have different information processing speeds, which are expressed in digital symbols on them. For a unified designation, a standard classification of card speed characteristics has been adopted, called "Speed Class", which reflects the data writing speed.
Download the program from the manufacturer's official website and run the installation executable file. The installation wizard will launch, which in a simple step-by-step mode will help you install on your personal computer or laptop. Installing the program does not take much time and does not cause any difficulties, even for inexperienced users.
Once the installation process is complete, launch the program. will perform an initial analysis of the system and display in its window all installed and additionally connected disks and data storage devices.
The program interface is as similar as possible to a file explorer "Windows", thereby allowing everyone, even a novice user, to work with it. Find your memory card in the list of partitions and double-click on it. The program activates the launch of the File Recovery Wizard, which, in a step-by-step mode, will offer to set certain parameters before starting the file recovery process.
Place an indicator (dot) in a cell “Full analysis (searching for all possible information)”. In the activated section, leave the cells unchanged "FAT (USB media, digital cameras, Windows 9x)" And “Deep analysis (search by file contents)”. These settings will allow the program to restore the file system of the memory card and conduct signature analysis "SD" card and restore all the information on it, even that which was deleted many months ago.
After selecting the analysis type, click the button "Further" to start scanning the marked card. The entire process will take place in real time and users will be able to monitor its execution using a status indicator.
Wait for the analysis process to complete "SD" memory card and press the button "Ready" upon its completion. Depending on the degree of damage to the memory card, its capacity and other parameters, the analysis may take from several minutes to several hours.
The window will display a list of all found files and folders that were recovered by the program. When you click on each file, its contents will be displayed in a preview window so that users can familiarize themselves with the final result before saving the required files, and make sure that they are fully functional. Mark the required files and folders and click the button "Restore", presented in the form of a lifebuoy and located on the main menu panel.
The File Recovery Wizard will open a pop-up window in which users will need to indicate the appropriate method for saving the marked files in this particular case. The wizard offers a choice of using one of four methods: save data to any hard drive or external drive, write files to an optical storage medium "CD/DVD - disk", create a virtual "ISO - image" or download data using "FTP protocol". Place an indicator (dot) opposite the cell indicating the method you have chosen for saving files, and click the button "Further".
Depending on the chosen method, in the next window of the File Recovery Wizard, specify the necessary options for saving files, and click the button "Restore" to complete. For example, when choosing a method "Save to hard drive" You will need to set the save path and check or uncheck additional settings.
Now all your files are recovered and saved to the safe storage location you specified. Open the files and make sure they are completely intact. Then you can carry out the formatting procedure "SD" memory cards for troubleshooting possible problems using one of the previously described methods.
You can fully explore all the capabilities of the program, get acquainted with its capabilities and advantages on our video channel in the manual: “Recovering files from a memory card of a camera, phone, tablet, video camera, recorder”.
Conclusion
With development various types Computer devices have seriously increased the number of types of information storage that users use to create, exchange and store their data. Lightweight and miniature memory cards are widely used and deservedly recognized by users, especially when creating photographs and images.
However, memory cards are not durable and can become unusable for various reasons, limiting the user's access to them or completely losing their data. Knowing some of the main signs that serve as a harbinger of a breakdown, as well as having knowledge of the reasons that caused damage to memory cards, users can, following a certain procedure, repair damaged cards and restore all the data stored on them.
Also, to increase data security and save yourself from additional costs, loss of time and effort, users should regularly back up their data and use alternative storage sources.
It often happens that all the important information that is on the flash drive disappears due to some circumstances. All you can do is look at the empty folder and hold back your tears, because it will take many weeks to restore a huge amount of important work information. However, do not despair and write a letter of resignation, because you can recover data from an SD card or a regular USB drive.
Why does information disappear?
It would seem a primitive question. In fact, there are many more reasons for data disappearance than banal formatting.
- The flash card is infected with a virus. Often virus programs“eat” information on the data storage or damage separate files. At best, they change the encoding of documents, which is why incomprehensible hieroglyphs are visible. To avoid this, you just need to have an antivirus on your computer and not give the media to just anyone.
- The memory card was not removed correctly. Safe removal they didn't just come up with it. With this function, the information is guaranteed to remain intact. If the flash drive is roughly pulled out of the connector, there is a chance that it may be damaged or stop working altogether.
- Formatting. The simplest and most common way to lose information. It’s also the most offensive, because the information disappeared due to one’s own stupidity.
There are many more reasons for data loss, but these are the most common.
What's really going on?
During deletion or formatting, files are permanently deleted and the space they occupied is freed up. You can easily verify this by going to properties. Actually this is not true.
A memory card, in essence, resembles a tray with many cells of a certain size into which information is placed. During deletion, information about the location of files and the weight they occupy is deleted from the memory card, which can be seen by going to properties. But physically the documents remain in their place. And, in fact, there is no deletion, since new documents are overwritten over old ones. This is why data recovery from SD card is possible.
The main thing is to fulfill one condition: under no circumstances should you write new information onto a formatted flash drive, because the files will be completely or partially overwritten, and it will no longer be possible to return them. If this condition is met, you need to use a special recovery program.
R.saver
A free utility for the countries of the former USSR (as the manufacturer himself writes), with which you can recover data from an SD card. The program is simple, and even a beginner will find it quite easy to understand. It works with FAT, NTFS and exFAT systems. Installing it is easy, just unzip and run the r.saver.exe file.
In the window that appears, we see a list of sections. Select the one on which you want to restore files. In the window that appears, select the desired folder and click “Scan”. In this case, the program will display confirmation of sector-by-sector scanning. It is necessary if the information has been formatted. In this case, click “Yes”. If it was simply deleted, a quick scan will suffice. You need to click "No". After scanning we find the necessary damaged documents, click on them right key and select “Copy to...”. That's it, data recovery from the SD memory card is complete.
Recuva
Quite a powerful and completely free, easy-to-understand SD card data recovery program for those who are doing it for the first time. Downloads and installs without problems. The wizard opens quick launch and, after several consecutive transitions, the program itself scans the disk. But if you need to recover data on an Android SD card, click on advanced mode in the right corner.
Disk selection buttons will appear. Having selected the disk, click “Analyze” and wait for the scanning to finish. You can immediately notice that all files are divided into colors. Files marked in green are “excellent” in condition. They can be restored without problems. Yellow - “medium”, which is difficult to restore. Red ones are “lost” and cannot be restored. Select what you need and click on any file right click mouse and select “Restore Selected”. We choose where to save, and data recovery from the SD card is complete.
PC Inspector File Recovery
Same free utility, which will recover data from an SD card after formatting and return lost information. Downloading and installing it is not difficult. After launch, you will need to select a language (by the way, Russian is present). Next, we are given an overview of all the functions and capabilities that it is capable of. this utility. After reviewing this information, we find ourselves in the program panel. Here you can see many different buttons and tabs, but in this case the most interesting is the top one.
Once there, select the “Logical Disk” section, where you need to click on the one you need to highlight. To start scanning, click on the green checkmark. We wait for the scanning to finish and see a list of lost documents. Mark the ones you need and right-click “Save to...”. Select the future location and click on the green checkmark. Now you can enjoy the restored data.
Hidden files
There is also a virus walking around the network that makes all files hidden, and the antivirus does not help. In this case, the files remain in place. You can verify this by looking at the properties. You can return files in the following ways:
What should I do so that data recovery from the SD card is not required?
It’s best not to take things to such an extreme and save time and a couple of million nerve cells. To do this, you just need to be a little more careful and remember simple recommendations:
- You must have an antivirus on your computer, because without it you can easily catch something. In addition, it is worth installing an extension in your browser that will show unwanted sites as a result of searches.
- Try not to give the flash drive to anyone, as the virus can be caught on someone’s computer.
- Always make a backup copy of your card.
- Watch where you click. Everyone has deleted it at least once by accident or stupidity. required file. Therefore, you need to watch what you select and click.
- Before you go through the trouble of restoring, check your recycle bin. Perhaps the deleted document is there.
- Create a clear structure on the disk and keep information strictly in the appropriate folders. Individual folders are much easier to scan than the entire disk.
But it’s still very nice that data recovery from an SD card is possible.
Epilogue
Once again, it is worth emphasizing that if information has been erased, you should under no circumstances overwrite it with new information, as restoration will become impossible. It’s better to avoid losing it altogether by following simple recommendations.
Now almost every mobile device has information storage in the form of memory cards of various formats. And the most popular are SD cards. They are widely used in photographic equipment, mobile phones, Mp3 players and electronic books. And it often happens that when downloading or uploading a file to the device, a failure occurs, and all the data on the card disappears somewhere. But this is not scary if you know how to recover data from an SD card. This is exactly what this article will talk about.
Why do you need to restore?
Lost data can be very valuable. For example, a family photo archive or video, and perhaps also important documents or music. And losing such information is quite unpleasant, especially when backup copy No. This is where data recovery from an SD flash drive is required.
For this procedure you need:
- universal card reader, in order to read the media;
- memory card with missing data;
- Internet access;
- computer or laptop.
Reasons for data loss
There are many reasons for the loss of information, here are some of them:
- unscheduled memory formatting;
- accidental deletion of files;
- violation of the file system structure;
- malfunctions leading to damaged areas of the storage medium.
Understanding the main cause of the problem, it will be possible to select the optimal recovery option and return all the information back.
When the computer or mobile gadget formats the drive, the file system layout table is cleared and repartitioned. The same thing happens with the boot area. This process causes the SD card to appear as blank media on the device. But this does not mean that the files are destroyed. Knowing this, we can come to the conclusion that it is still possible to recover information on a formatted flash drive.
However many gadgets are capable of overwriting data when formatting, in which case returning files will be more difficult. This happens because the device, after re-partitioning the card, begins to replace zeros in all areas of its memory with OxFF. Which, of course, completely destroys all traces of previous data.
After accidentally formatting the media, you should immediately stop using it and try not to write any more data there. If new files are written, they will be superimposed in place of the old ones, overwriting them. This deprives you of the chance to restore everything back.
Next, of course, you can contact service center to perform data recovery from the SD card. The price for such a service in some workshops can be quite high, so it is better to familiarize yourself with this procedure and try to restore the information at home.
As soon as it becomes clear that the drive has problems, that is, it is not detected by the device or shows the wrong volume, then you should immediately try to copy all the available information from it. Next, you need to format the flash drive and check for viruses and bad sectors.
If the data on the SD card is unavailable, then you need to recover the missing files. To do this you need use the software intended for this purpose or carry out hardware repair of the media, if the first does not help, and the flash drive is not detected at all.
The first option, using programs, is more accessible and uncomplicated. And knowing how to do it, anyone can handle it. Thanks to this method, it is possible to recover data after accidental failures and formatting.
The sequence of actions to restore information will be as follows:
- You need to download and install the application for resuscitation. Such programs are paid and freely distributed.
- Turn off the gadget and remove the memory card from it.
- Insert the flash drive into the card reader and connect to the PC.
- Launch the program and search for lost files.
- Save the found information to HDD computer.
- Format the drive and check for errors.
Hardware repair occurs due to mechanical damage to the storage medium. In this case, the final outcome of the repair will directly depend on what exactly is broken and how badly damaged the flash drive is. This procedure is not easy, and requires the intervention of a specialist and special equipment for repair.
Applications to recover lost files
The successful resuscitation of deleted data is influenced by what software is used. There are many solutions to the problem on the Internet. But not all are convenient and give good results. Here are the ones that perform their functions best:
- PhotoRec for photo recovery.
- Recovery-studio.
- R. Saver.
PhotoRec
This program makes it possible to return graphic files after accidental deletion or formatting. Application allows you to recover more than 150 digital data formats. This is a multi-platform program. For each operating system you can download your installation package and use it in almost any OS.
This application fits well with the additional TestDisk utility, which can return a deleted partition on a memory card.
R-studio
This is very popular app both among specialists and ordinary users. The program allows you to work on any file system. In some cases she can return information even if hardware damage occurs.
The process of resuscitating files using R-studio goes like this:
- You need to install the application on your computer.
- Launch the application. IN open window All connected drives will be visible.
- Next, you need to select the desired flash drive, right-click it context menu and begin the process of scanning deleted information.
- A new window will immediately open in which you need to mark the area to search.
- You also need to tell the program where to save the recovered data and select the type of files that need to be found and returned.
- At the end of the process, the data will appear where you specified when setting up the scan; now you can save it to a more reliable medium.
R. Saver
This application has a Russian interface and is a very reliable and effective product from R. Lab. R. Saver also differs in that the application does not require installation and is launched immediately from the downloaded file.
The resuscitation procedure using the program goes like this:
Repairing an SD card with damaged firmware is more complicated than simply restoring files. But this method of resuscitating a host is also possible. If the flash drive was suddenly disconnected during the copying process, this could damage the firmware embedded in the SD card controller. This naturally leads to device failure.
To restore the firmware you need:
- Find out the microcontroller model, on which the memory card circuit is based. This information can be found on the chip itself.
- To do this you need to carefully open the case flash drive and find the markings on the chip.
- Then you need to go to the address and find the line there, which indicates the controller model.
- In the same line there is a link to download the flash driver program. You need to download it.
- Using this application, you need to load the firmware into the SD card controller.
This short description the process of restoring the functionality of a damaged flash drive. And it is written only to familiarize yourself with the procedure for repairing a storage device. More detailed guide you need to search separately for each flasher.
Restoring a file system using Chkdsk
The most accessible method to bring back to life a memory card with a damaged file system is to use the built-in Windows utility Chkdsk. It runs from command line And allows you to put the drive structure in order without losing data. This procedure is carried out as follows:
- The flash drive is connected to the computer.
- After appearing in Explorer, you need to find out what letter the system assigned to this medium (let’s imagine that it is the letter “F”).
- Next, you need to launch the command line.
- In it, enter the command “chkdsk F: (letter assigned to the flash drive) /f”, which will scan the memory card for errors and, having detected them, make corrections.
- Once the process is complete, you need to check the SD card again and test how it writes files.
Map re-partitioning or low-level formatting
Any flash drive, like a hard drive, can also have two or three partitions. Most often, after purchase, it is marked up for one volume, but this can be changed if necessary. In addition, it is possible to completely clean the media and remove all traces of information on it, as well as erase all sections, making it absolutely clean. This process is called low-level formatting.
Attention! Just like simple formatting, low-level formatting deletes files, but after such a procedure it will no longer be possible to restore them. Therefore, before using this method, it is better to copy all data to another medium in advance.
After this, you can create a new volume on an empty area of the SD card. This procedure often helps out when a flash drive connected to a computer is detected as RAW. Or when it shows that the device is connected, but the partitions are not visible. The most the best option for low level formatting is application "Low Level Format Tool". Next, let's look at how to use it:
- First you need to run the program and connect the USB flash drive to personal computer. After the application opens, all disks installed on the computer will be visible in the window. You need to allocate an SD card. Make sure you select the correct media before continuing, otherwise you may lose important information located on another disk.
- If you are not sure, then look at the Capacity column, it indicates Exact size selected drive. Once you are sure you can continue, click the “Continue” button. In the new window you need to switch to the “Low Level Format” tab. Next, click the “FORMAT THIS DEVICE” button. The long formatting process will begin and complete cleaning SD cards. The time of this operation depends on the speed and capacity of the memory card.
- At the end of the program, there will be empty unallocated space on the media that needs to be reinitialized and partitioned. To do this, call the context menu on “My Computer” and select “Management”. A new window will open, in the left section of which, go to the “Disk Management” line. This is a built-in disk utility that allows you to partition and format disks connected to a personal computer. Mark the processed card in it and right-click on the leftmost part of it. Select "Initialize disk" from the drop-down list.
- After completing the procedure, you need to call up the menu on the black area of the flash drive and click on the “Create a new volume” item. Following the wizard's prompts, you will need to specify the size (if the flash drive consists of one partition, then you do not need to change anything here) and the type of file system (NTFS or FAT32). After confirming the specified parameters, marking and formatting will begin, as a result of which a fully working SD card will appear. That’s it, now you can download the saved information back onto it and insert it into your smartphone or camera.
