How to recover information from a damaged sd card. How to recover photos from MicroSD memory card or USB flash drive

Many have encountered the disappearance of files from microsd memory cards installed in cameras, tablets and other gadgets. This can happen when the storage media is physically damaged, software problems, a virus attack, or accidental deletion of information by the user. Knowing the cause of the failure, you will be able to recover the missing data with maximum efficiency.

Attention! If even the slightest malfunction of the flash drive is detected, it is recommended to immediately perform backup important data and only then deal with the problem.

If you didn’t have time to save the information in a safe place, you need to remove the micro SD media from the gadget and in no case write new information to it. This is due to the fact that when recording (resaving), new files can completely overwrite the remnants of old ones. In this case, the chances of their successful recovery are sharply reduced..

Ways to reanimate microsd memory cards

Depending on the reason for deleting data from a microsd memory card, the following can be used for resuscitation:

• special programs (R.Saver, R-Studio, Recuva, etc.);
• hardware intervention;
• mechanical recovery of the memory card itself.

Programs for resuscitation of lost information

The success of recovering a micro sd flash drive largely depends on the resuscitator program used. There are a lot of such programs on the Internet. Most of them work on the same principle. Therefore, having dealt with one utility, you can easily master others. As an example, consider how to recover data lost from microsd using the popular R.Saver program.

This utility is considered one of the best of its kind, due to its versatility, efficiency and ease of use. R.Saver allows you to restore access not only to accidentally deleted or infected files, but also to a fully formatted micro SD card.

To recover data lost from a flash drive, you must:

Data recovery by hardware

The R.Saver program and similar utilities are suitable for resuscitating data from healthy microsd media. But what to do with damaged cards? Restoring lost files and folders from a faulty micro sd memory card will be much more difficult, but if you follow the instructions exactly, there is a way out even from this situation.

All micro SD flash drives are equipped with microcontrollers, the operation of which is controlled by special programs. Over time, they begin to fail and may even fly off. This causes the card to fail.

In this case, to reanimate the storage medium (rewrite the control program), you will need:

To correct mechanical damage to a micro sd memory card, it is better to take it to a workshop, since it will be very difficult to repair at home without specific equipment (a soldering iron with a thin tip for microcircuits, a magnifying glass, etc.). However, the services of a specialist are paid, so consider whether the information posted on the flash drive is really worth paying for.

For the average smartphone user, the data stored on the phone and memory card is more important than the device itself. Therefore, if the microSD drive is damaged, people are more afraid for the safety of data than for the performance of the flash drive. So let's take a look at how to fix SD card corruption on Android and recover data.

Causes of damage

Nothing is eternal. This statement is also true for removable media. Perhaps your card has exhausted its resource and has gone to another world. But there are still a number of reasons why this problem occurs:

1. Error in the smartphone OS. Invisible android processes or any other mobile operating system more or less often lead to errors that leave a certain imprint on the performance of flash memory.
2. Legacy file system. If your SD card uses FAT, this may cause errors as some modern applications no longer work with this standard and interact incorrectly with the device.
3. Emergency shutdown of data transmission. If you disconnect the USB cable while copying files from a PC to the phone's flash memory, with a probability of more than 50% damage to the SD card is irreversible.
   

   Attention! Never turn off the device before the end of the data transfer process. Cancel the operation if necessary!

4. Incorrect removal of the drive. When removing the flash drive without first disconnecting, there is a risk of data corruption and loss of SD card performance.

How to recover an SD card

To recover data and disinfect a flash drive, follow these steps:

But there are situations when the memory card does not open on the computer. This is a bad sign, and in this case, you should turn to third-party data recovery utilities.

For this you need:

1. Repeat steps 1-3 from the previous instructions.
2. Download the Recuva app.
3. After starting the program, a wizard will appear to help you. Press "Next".
   
   
4. Select the type of files you want to recover (images, documents) and click Next.
   
   
5. In the new window, click on the option "In the specified location" and select the SD card. Click next.
   
   
6. Wait until the end of the operation.
   
   
7. After the "return" of the long-awaited content, repeat steps 5-8 of the previous instructions.

The above actions will help to return some of the valuable information.

Advice! To prevent such situations, it is recommended to back up important files regularly!

If the removable media is not detected by the computer, it will not be possible to independently access the data without certain skills and resources. Therefore, if necessary, contact service center removable media repair. Now you know how to fix SD card corruption on Android.

Software failures, viruses and improper operation are the main causes of microSD card failure. However, most drives can be restored at home. You will need a computer, a card reader - a card reader, a careful reading and a choice of how to restore an SD card or micro SD flash drive.

Method 1: Format the Drive

A software glitch, virus attack, or file system markup corruption is usually fixed with a simple format. This action allows you to recreate the markup, remove malware, or hide damaged memory blocks. The card is formatted in one of the following ways:

1. Inside a mobile device.
2. Standard Windows tools.
3. through specialized applications.

Method 2: use a flash drive recovery program

If the memory card is damaged - the firmware has flown from the controller or the memory has worn out, in this case specialized recovery programs will help. For example EzRecover or D-Soft Flash Doctor, as well as others.

Method 3: Restoring with Service Utilities

Some drive manufacturers develop proprietary utilities for analysis and recovery. Such programs are downloaded for free on the official website.

The principle of recovery is based on formatting the media. At the same time, the memory is analyzed in the process, damaged cells are hidden, and the operation of the controller is also restored.

JetDriveToolbox only works with Transcend flash drives. The program will not see other drives.

Method 4: changing the controller firmware

Conclusion

The methods described above will tell you how to restore a micro SD flash drive. Use media formatting as this method is effective in most cases. If there is no result, use flash drive recovery programs or proprietary utilities. Also try to reflash the controller if other methods did not solve the problem.

I received a request on the topic "MicroSD memory card is not detected." The full text of the request is below in the screenshot.

As you already understood, the client was interested in the possibility of repairing a damaged memory card. After carefully reviewing the sent pictures with damaged memory cards, I came to the conclusion that there are chances to recover data from a damaged microSD, and they are pretty good.

As for the possibility of repair, the opposite is true here. In the case when there is physical damage, then there can be no talk of repair. And it's not even about this particular case, but about the situation as a whole. MicroSD card production technology does not imply repair options, although there are exceptions, but this is an exception to the rule. You can learn about repairing flash drives in my blog blog ..

Reminder:All -micro and -mini SD are monolithic flash drives, with all the consequences. You can read more about data recovery from monoliths in this publication.

Important:If there is important data on the card, and the microSD (microSD) is not working, then you should think about the need for repair. Repair can destroy all data, without the possibility of further recovery of information.

What to do if MicroSD is not detected

The fact is that almost all memory cards, for the most part, cannot be repaired, but there are some nuances. So, for example, I had cases when clients brought me such memory cards, well, completely with "childish" problems. Below I will give a couple of examples.

Case #1

The client calls, they say I had an SD card in the camera, but one day it was no longer detected in the device, and there, well, “mega important pictures” are. First of all, I thought that there was a problem with the card controller, but everything turned out to be trite and simple.

Solution. It turned out that the client did not have an SD card at all, but a microSD inserted into the SD adapter (photo example below). After removing the microSD from the adapter and connecting via a card reader, I was able to access the contents of the disk in the normal mode (without any "unknown" manipulations) and copied the data to the client's flash drive. For this, I was even ashamed to take money. Here such cases happen.

The thing is that SD adapters are a very unreliable “device” and you should not trust him. The strangest thing for me is that even some professional photographers use such a crutch, which I still cannot understand.

Case #2

Contacts are oxidized. There are also cases when oxides appear “banally” on the card connector. In such cases, the microSD is not detected by the phone or any other device to which it is connected.

Solution. The solution here is, well, very simple, and for this we need - the usual stationery gum and a cotton swab with industrial alcohol. In general, you can do without alcohol, but how can we do without such a “device”. To eliminate oxidative processes, you need to take an eraser and gently (without the use of brute physical force, but without gentle rubbing) go over the contacts with an elastic band until they become shiny as in the photo below. After making sure that the connector contacts are well cleaned, you need to apply a little alcohol on the ear stick and clean the contacts and wait until the alcohol dries.

On this, perhaps, the article on what to do if MicroSD memory cards are not detected can be considered closed. All good mood and life without breakdowns that could not be fixed.

Data loss is an annoying problem that can happen on any digital device, especially if it uses a memory card. Instead of getting depressed, you just need to start recovering lost files.

It should be noted right away that 100% of deleted information cannot always be returned. It depends on the reason for the disappearance of files: normal deletion, formatting, error, or failure of the memory card. In the latter case, if the memory card does not show signs of life, is not detected by the computer and is not visible in any program, then the chances of recovering something are very small.

Method 1: Active File Recovery

One of the most powerful utilities for recovering data from any media, including SD and MicroSD cards.

It is extremely simple to use:

Method 2: Auslogics File Recovery

This tool is also suitable for recovering any type of lost files. The interface is made in Russian, so it’s easy to figure out what’s what:

If nothing was found in this way, the program will offer to conduct a deep scan. In many cases, it is effective.

Tip: Make a rule for yourself at regular intervals to dump the accumulated files from the memory card to the computer.

Method 3: CardRecovery

Designed specifically to work with memory cards used on digital cameras. Although in the case of other devices it will also be useful.

File recovery involves several steps:

In the specified folder you will find the deleted contents of the memory card.

Method 4: Hetman Uneraser

And now let's move on to such underdogs in the world of the considered software. For example, Hetman Uneraser belongs to the little-known, but in terms of functionality it is not inferior to its counterparts.

A feature of the program is its interface, stylized as Windows Explorer. This makes it easier to use. And to recover files with it, do this:

As you can see, Hetman Uneraser is a rather interesting and non-standard program, but, based on the reviews, it recovers data from SD cards very well.

Method 5: R-Studio

Finally, consider one of the most effective tools for recovering portable drives. You won't have to figure out the interface for a long time.
