Memory cards (microSD) are often used as additional data storage on mobile devices. Losing access to this storage can be a real disaster for the user, because many people keep photos and other personal files on them, which often exist in a single copy. In addition, access to applications that were located on this media is lost.
Why can’t my phone see a memory card or USB flash drive that was working and read properly just yesterday? How to solve the problem on your own?
How to figure out the culprit
The source of the problem can be software and hardware errors both in the memory card (flash drive) itself and in the phone.
The reason is most likely in the card (flash drive) if:
- It is not detected or detected but not read by different devices.
- It stopped being read immediately after using it on another device.
- It has visible mechanical damage.
- When inserting a card into the slot (connecting a flash drive), the phone freezes, reboots or turns off. Provided that it reacts normally to other removable media.
The culprit is most likely the phone if:
- It does not detect or detects but does not read any microSD card or flash drive.
- When installing any card or connecting any flash drive, it turns off, reboots or freezes.
- The card slot (USB connector) has visible mechanical damage.
- The failure was immediately preceded by some actions with the phone: installing applications, updating firmware, anti-virus scanning, resetting to factory settings, etc. Or accidents - impacts, falls on the floor, etc.
When connecting flash drives with a full-size USB type A connector to mobile gadgets, OTG cables and adapters are used, which are also often the cause of such situations.
Unfortunately, in many cases there are no obvious signs of “guilt” of one or another device. For example, when a card or flash drive is not detected by a specific phone, while others read it normally, and the phone regularly reads all drives except this one.
Why are memory cards and flash drives no longer detected and read?
In about half of the cases, the cause of the failure is a drive failure. I already talked about the site. The same thing can happen with a card. In addition to the problems described, they often encounter another one - the formation of an oxide film on the surface of the contact group, which creates an obstacle to the exchange of data between the card and the phone. In addition, being small and fragile, micro SD cards are easily broken mechanically, much more often than flash drives.
Another group of reasons is programmatic in nature, that is, it is associated not with the drive, but with its contents. Among them:
- Unrecognized file system. This can happen if the card or flash drive was previously used on a PC running Windows and formatted in NTFS. Or it was in another smartphone and was formatted in exFat. For removable media to be readable on any version of Android, it should be formatted in FAT32.
- The removable drive is infected with malware. The reason for the lack of access to it may be blocking by the antivirus that runs on the phone, or the actions of the malicious program itself.
- The file system of the memory card or flash drive is damaged. Reasons: incorrect shutdown (for example, during recording), use on a faulty device (including connection to a faulty reader or adapter), unstable power supply, viruses, etc.
Why doesn't my phone detect or read memory cards and flash drives?
Reasons on the phone side can also be hardware or software. The first group includes:
- Mechanical failure of the memory card slot or USB connector. Often easily identified by eye. In this case, the phone most likely will not recognize any SD card. And if the USB socket on it is broken, then there will be problems not only with reading flash drives, but also with charging.
- Malfunctions in the electronic components of the board. A failure can manifest itself in the fact that when installing any drive into a slot, the phone freezes, reboots, etc. Or an apparently intact slot and a working card are not detected in the system in any way. Or they are identified and disappear.
- Malfunction of devices connected to the phone (SIM cards, etc.). It manifests itself in the fact that problems with recognizing a memory card (flash drive) arise only when connected together with a faulty device.
Software reasons:
- Incompatibility with microSD cards of a certain type or size (lack of driver). In such cases, cards can be detected, but incorrectly and without access.
- Operating system failure. It appears as errors “SD card does not work” and other similar ones. Or the removable media is not detected at all.
- Installation of blocking applications.
- Virus infection of the phone.
How to fix the problem yourself
Below is a sequence of actions that will help you fix the problem in about 80% of cases (in the rest, only a service center or buying a new drive will help you out). If the previous action did not give the desired result, move on to the next one. Recommendations for flashing devices are provided for reference only. They are performed at your own risk.
If the likely culprit is a card or flash drive:
- Make sure there are no mechanical failures of the drive. Some of them (the connector blade) can be easily removed with your own hands if you know how to use a soldering iron.
- Clean the memory card contact group with an eraser or wipe with alcohol. This will remove the oxide layer from their surface and restore signal transmission.
- Connect the media to your computer (if you are using a reader or adapter, make sure they are working). Make sure its file system is supported by your phone. If not, format to FAT32. Do not forget to first copy the information from it to another medium, for example, to a PC hard drive.
- Scan the media with an antivirus program.
- Check it for file system errors. To do this, you can use a standard Windows tool (the chkdsk utility, which is used to find and fix disk errors): open the drive properties in Explorer, go to the “Tools” tab and click “Check”. In the next window, check “Automatically correct system errors” (by the way, in Windows 10, auto-correction of errors is enabled by default, so this window does not appear).
- If the probable cause is a failure of the firmware of the flash drive, in some cases it can be restored using service software, which can be found on specialized web resources. However, after this procedure there will be no data left on it. In addition, if the firmware is unsuccessful, the drive may completely fail.
If the likely culprit is the phone:
- Make sure there is no mechanical damage to the memory card slot or USB socket.
- If a slot has not been used for a long time, dust may have accumulated in it. If possible, remove it with a brush or dry cotton wool wrapped around a toothpick. If the slot contacts are accessible, remove the battery from the phone and clean them with alcohol.
- Disconnect all external devices from the phone, except for the problematic drive, and restart the system. If after this it is detected normally, the reason is something disabled.
- Scan your phone for malware infection.
- Uninstall apps that you installed shortly before the crash.
- Temporarily remove your antivirus (it may block removable media).
- Do a factory reset.
- Reinstall your phone's operating system.
If the likely culprit is not identified, use the recommendations from both groups that best suit your situation.
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 quite good.
As for the possibility of repair, it’s the other way around. In the case where there is physical damage, then there can be no talk of repairs. And it’s not even about this specific case, but about the situation as a whole. The microSD card production technology does not provide options for repair, although there are exceptions, but this is the exception to the rule. You can find out about repairing flash drives in my blog blog..
Memo:All -micro and -mini SD are monolithic flash drives, with all that it implies. You can read more about data recovery from monoliths in this publication.
Important:If there is important data on the card, but the microSD (microSD) does not work, 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 have had cases when clients brought me such memory cards with, well, “childish” problems. Below I will give a couple of examples.
Case No. 1
A client calls, saying that I had an SD card in the camera, but one day it was no longer detected in the device, and there were “mega-important photos” lying there. The first thing I thought was that there was a problem with the card controller, but everything turned out to be banal and simple.
Solution. It turned out that the client did not have an SD card at all, but a microSD inserted into an 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 normal mode (without any “unknown” manipulations) and copied the data to the client’s flash drive. I was even embarrassed to take money for this. Such cases happen.
The thing is that SD adapters are a very unreliable “device” and should not be trusted. The strangest thing for me is that even some professional photographers use such a crutch technique, which I still cannot understand.
Case No. 2
The contacts have oxidized. There are also cases when oxides appear “commonly” on the card connector. In such cases, the microSD is not detected by the phone or any other device it is connected to.
Solution. The solution here is very simple, and for this we need a regular rubber band and a cotton swab with technical 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 carefully (without using brute physical force, but also without gentle rubbing) rub an eraser over the contacts until they become shiny as in the photo below. After you are sure that the connector contacts are well cleaned, you need to apply a little alcohol to the ear stick and clean the contacts and wait until the alcohol dries.
At this point, perhaps, the article about what to do if MicroSD memory cards are not detected can be considered closed. I wish you all a good mood and life without breakdowns that could not be fixed.
If you have any questions about this topic, write in the comments under the article.

Most users of mobile phones and smartphones are faced with a situation where the phone does not see the memory card. Sometimes this question arises immediately after purchasing a device, but most often it breaks down later, having already become an integral part of everyday life and accumulating important files. There are many reasons why a flash drive is not displayed on the screen and, with some effort, the owner can always eliminate them.
If the phone does not see the memory card, it may be a software problem; this is the factor that is detected in half of the situations. Just as often, defects are the result of a banal flash drive failure; here only a replacement will help, although modern capabilities allow you to recover data from damaged media.
If you lack time and desire, there is always the option of turning to the specialized services of a service center, but they cost money and will cost more than the flash drive itself. Instructions for restoring the browsing function apply to all generations of mobile devices, including older versions. In these cases, in response to the question: why doesn’t the phone see the memory card, one can only throw up one’s hands: he’s tired, he’s leaving. But! Data can always be reproduced in full!
In extreme situations, a reading device will help, from which they can all be easily transferred to a PC.
Factors due to which the phone does not see the memory card
When wondering why the smartphone does not see the memory card, its owner needs to analyze the following points:
- Why did it fail;
- Find out the current state;
- Clarify the causes of failures;
- If they relate to software, then why does Android not see the memory card.
Then based on the results
- Format via PC;
- Format via smartphone.
It must be remembered that when installing a flash drive for the first time, difficulties are often caused by its capacity. This is especially true for outdated models that are unable to support modern products. 
If the new phone does not see the memory card, what to do will tell you the following list, which lists the main problems and ways to solve them.
- File system failures. The most common problem that can be resolved by reformatting the flash drive;
- Poor connection to flash reader. The flash drive must be inserted more tightly, and then the mobile phone must be rebooted;
- The phone does not see the memory card because the reading connector is completely faulty. Only contacting the specialized services of a repair center will help here;
- The flash drive simply burned out. It will no longer be possible to revive it, but there is still hope for data recovery. Modern capabilities make it possible to do this.
The phone does not see the memory card. Procedure
First of all, it needs to be rebooted. Usually this procedure is enough to fix software failures and other difficulties. If after rebooting the phone does not see the microSD memory card, you need to remove the outer cover and take out the battery, behind which the flash reader is located and check the contacts. In other models, the socket is located on the side, here you also need to try to press it more tightly to the contacts. The main thing is not to overpress, so as not to cause mechanical damage. 
When there are no positive results, the product is tested on another device. The ideal option is a card reader connected to a computer. Another mobile device would work just fine. If it and all the stored information are available, it means that the problem is in the smartphone and repairs are no longer possible. The main causes are caused by software flaws or damaged contacts. 
When another phone does not see the memory card, we are talking about either defects in the file structure, or the flash drive has simply burned out. In this case, it can no longer be restored, whereas file failures can be easily eliminated by simply formatting the product.
Format using PC
You must remember that during the process all information from the drive will be deleted. If you are not sure that the memory card is not visible on the phone due to software problems, and the stored information is important, it is better to take it to a repair service.
In another situation, you need to format the flash drive in the following sequence:
- It is placed in the reader and then in the computer connector;
- The launch should start automatically. If this is not the case, it means that the phone has stopped seeing the memory card due to its problems. You need to go to “My Computer” and look at the list of available connections. The absence of a storage device in it indicates that it has burned out;
- When there is a display, right-click it and activate the “Format” option;
- A menu appears on the screen where the user must select a format. It is represented by 2 types NTFS and FAT. The lion's share of flash drives belongs to the FAT standard, which is chosen from the very beginning. If there are no positive results, you can try NTFS;
- Having determined the format, the owner activates the “Start” option and waits for the operation to complete;
- Next, the formatted flash drive is checked again to see if it works. It happens that at this stage all questions are removed.
In the absence of a card reader, all actions can be easily performed using a mobile device.
Format without a computer
So, what to do if you don’t have a card reader, PC or laptop. It doesn’t matter, the product can be easily formatted using a mobile phone, you just need to go to Android “Settings”. They are located in the corresponding list, where the owner can use the “Disable” and “Remove” functions. Most current devices immediately prompt the owner to format the drive. You should not perform the operation right away, because, just like in the case of a computer, the operation completely erases all stored files.
Before this, you need to check the contacts again, eliminating the possibility of a weak connection. After making sure that the connection is sufficiently dense, the user begins the actual process.
– Select the “Clear” option from the menu. It takes little time and usually takes one minute. Then the “Connect SD card” function is activated in the menu and if there are no mechanical faults, it is ready for use.
When understanding the reasons, you should remember about different versions of Android firmware. The order of actions depends on this. In other operating systems, the procedure is performed in a similar way; just find the “Settings” category
Some smartphones do not have a memory card slot. As a rule, we are talking about flagship devices, where, according to the creators, there is no room for a flash drive. Still, most smartphones support a memory card. This is good, you say, and you will be right. But sometimes the device may not see this same memory card. Why and what to do in this case?
Restarting the device
The first step is to restart your device. For what? If your phone or tablet uses a tray where a micro SD card is inserted, that is, the procedure does not require rebooting the device, this problem can be attributed to the most common failure. Therefore, the first thing you need to do is reboot the device.
The problem is with the contacts
If you have another device at hand, be sure to insert the memory card into it and look at the result.
Format the card
But often everything is much simpler and the problem is related to formatting. You need to format the micro SD card. To do this, insert it into the card reader and connect it to the computer. When the card appears in the list, right-click on it and select Format.
In the new window, select the FAT32 file system and click on the “Start” button.
Unfortunately, this will delete all your data, so we highly recommend moving it to another location if you need it.
After formatting, insert the memory card back into the device.
Another option is to format the card on your phone (if possible). Please note that in this case all data will be deleted.
Go to the "Memory" section.
Then select "Empty SD Card".
Confirm the action if you agree.
The memory card will be formatted.
The problem is in the phone
If the card works on other devices (for example, the computer sees it), but does not work on one device, then the problem may be related to the device itself. For example, something was damaged when the phone fell. In this case, the only thing that needs to be done is to repair the device, having previously diagnosed it.
Memory card problem
This makes it even easier. We insert the micro SD card into other devices and check its functionality. If it shows no signs of life or shows errors, it may have reached the end of its life cycle. And the only thing that remains is to try to “get” important files from it, if there are any on the card.
Incompatibility of the memory card with the phone
It could also be that the memory card is incompatible with the phone. Such cases are rare, but still occur, if you believe the reviews. In case of incompatibility, the phone simply cannot read information from the card. There is only one way out - replace the memory card.
You can ask your questions using comments.
Hello, dear friends. In this article we will look at how to recover a memory card and how to restore an sd without much difficulty. This is a very pressing issue nowadays. Now almost any new electronics has a slot for a memory card of some type. The most popular formats are microSD, miniSD, SD.
Progress of memory card resuscitation
- To recover various data from SD, you need to install special software on your personal computer. It can be either free or cost some money.
- Then, using a card reader, you need to connect the memory card to a personal computer.
- Launch the program and, following the assistant's prompts, recover deleted data.
- Finish by saving the data to your hard drive.
This is not difficult. To transfer files from SD, various software will help you. It is recommended to have it on hand in case of data problems. This way you don’t spend a lot of time and you don’t need special skills. It is best to try to revive the card using the software suggested below.
SD Card Recovery Software
The most common program for recovering data from micro SD and SD is SD Card Recovery. This is a free program and it won't be difficult to find. It allows the user to recover deleted information from various flash cards. Files will be restored quickly.
SD Card Recovery is a modern utility, it is easy to learn and does not require special knowledge in the field of computer technology. It supports the following formats - micro SD, SD, MS, M2. Another feature of this utility is the recovery of information from damaged flash drives. It can recover files in mp3, mp4, jpeg, etc. formats. The recovered file will be returned to you without distortion. Restoring a micro SD flash drive using this utility is not difficult. Absolutely everyone can figure this out. To date, SD Card Recovery software has received many positive reviews from various users.
R-Studio program
Also, another free software that can help you with SD resuscitation is R-Studio.
On the official web resource they write that this program is not difficult to learn, but is capable of restoring a large number of files intact. It is an excellent substitute for SD Card Recovery.
Easy Recovery
Another means of returning files from a card is Easy Recovery. Some professional users praise its file recovery capabilities.
There are some problems that may arise when recovering data. Each of us can face them. Let's look at several ways to solve such problems.
If MicroSD is not detected
There may be several options.
Option 1. Sometimes your PC does not see the memory card, but how will you restore it then? There are 3 ways to solve this problem. Sometimes the flash drive is displayed with a letter. To solve this, you need to open Disk Management. To quickly open this window, you usually use the Win+R key combination. There you need to enter the command diskmgmt.msc. In the window that appears, select the flash drive, and then you need to select “Change the drive letter or path to it.” Then select another letter and save the changes.
Option 2: Often, after purchasing a new computer or updating the software, it may lack the necessary drivers. You need to install them. You need to go to the corresponding official website and find this driver there, and if you have a distribution kit on any medium, then use it. Drivers will help you identify connected devices on your computer. This is one of the easiest ways to fix the problem.
Option 3. The easiest way is to disconnect the flash drive and connect it to another device. This is not the best method, since you need to solve problems on the main computer before restoring the flash drive, but this method is the least time-consuming.
What to do if the PC does not see the flash drive or entire files? This means that your PC does not see the flash drive only partially (some files are present, but others are not). Many people think that their flash drive is broken and are trying to restore it. There is no point in drawing hasty conclusions. You can try to solve this problem by running a virus scan. Viruses can interfere with the normal operation of a flash drive. You need to insert it into your computer and check it with any antivirus.
Formatting SD and microSD memory cards
If it was not possible to recover data from the memory card, then it needs to be formatted for further use. There are times when, while using a flash drive, there is not enough space, and you urgently need to load files onto the flash card. When solving this problem, it is advised to copy all the files that were on the card and then format it.
There is also a situation when your personal computer or mobile device does not see the memory card and requires formatting it for further use of the flash card. If your memory card cannot be read after this procedure, then it is most likely broken. What to do if the memory card is damaged? Is it possible to restore it? A damaged memory card can be taken to service. There, with rare exceptions, they will help you restore a damaged flash card. Repairing a memory card can cost a lot of money, and there is no guarantee that all data will be restored. In the next paragraph we will look at how you can restore a microSD card at home.
Restoring a memory card can also be done at home. How to recover a flash drive? To recover a microSD memory card, the Hetman Partition Recovery program can help you. This is a program for recovering an SD card. This software allows you to find previously created disk partitions that were subsequently deleted. If your flash card cannot be read, then you can try this method. This program for microsd and sd recovery is suitable for use even by inexperienced and novice users of modern technical devices. Now you should not have any questions about how to recover an SD memory card.
Devices that will help with formatting
A personal computer is the most reliable device. It can be used to perform various actions with portable devices. To connect various types of cards (SD and microSD) to a computer, we need a card reader that will help the PC identify the memory card as a regular flash drive.
There is another way to connect and identify SD and microSD on a PC. This can be done using a cable that needs to be connected to your tablet/phone. For example, you have a memory card in your tablet and you want to open it on your computer. Connect your tablet and PC. The flash card will appear as a regular additional storage medium.
If your device (phone or tablet) does not have the function of formatting a memory card, then in this case you can use separate programs on your PC.
How can you format a flash card?
There are many programs that have this function. One good program is SD Card Formatter. She, like the others, will not be difficult to find. Let's figure out what SD Card Formatter is.
This formatter is free. The program will help you format various types of flash cards. The most common function of SD Card Formatter is SDXC and SDHC formatting. This program has many useful features, one of which is formatting flash drives by connecting Android devices to a computer. This flash drive recovery program is easy to learn.
How do you format microSD cards? Formatting a microSD is no different from formatting a regular SD, as is restoring a microSD memory card from an SD. This is done either using a computer with a microSD-SD adapter, or using your portable device that supports microSD.
Knowledge that will definitely come in handy
To avoid problems with SD, you need to take proper care of it from the very beginning. If you follow these points, then there should be no problems. Let's consider simple rules:
- There is no need to subject the flash drive to physical impact (do not drop it);
- Try to defragment the SD card;
- Periodically copy the contents of the drive to another medium, such as a computer. In the event of a malfunction, you can format the card and transfer the data back;
- There is no need to fill your memory to capacity. You must have at least 10-15% free space;
- You should try to remove the memory card rarely, and only using a special function that is available in new smartphones (Settings>Memory>SD Eject);
- Your flash drive should not lie idle; try to use it periodically.
Restoring a microSD card is, of course, not difficult. But the main thing is to take care of your storage media so that such problems do not arise in the future.

Android does not see the microSD flash drive (memory card) September 2017
What to do if Android does not see the microSD flash drive? This question often worries owners of smartphones and other gadgets, regardless of manufacturer and cost. Problems of obtaining data from a DVR or installing software on a tablet or smartphone can be solved independently if you know the main causes of the malfunction and how to solve them.
How the problem manifests itself
Virtual reality glasses
The most modern VR glasses for iPhone and Android smartphones, as well as for computers.
The malfunction manifests itself as follows: after replacing the micro-SD card, after rebooting, flashing or simply turning on the device, the gadget does not see the flash drive or its contents. As a result, data or installed software is lost, the camera and programs begin to write information to the internal memory of the device. The latter quickly becomes clogged, there is no space left for recording OS service information, and the gadget loses performance and begins to freeze.
As a result, if the internal memory is small, it becomes impossible to work without a memory card.
To fix the problem, you need to determine the cause of the breakdown. Very often it is possible to eliminate a defect yourself, without going to a workshop.
The phone does not see the flash drive due to formatting problems
The partition table can become corrupted on any file system (NTFS, ExFat, Fat32). As a result, Android cannot read files written to SD. Most often this happens when the user tries to format the memory card himself and performs incorrect actions. Another option is to insert a card with a different file system, for example, from a camera. You can restore the card's functionality by formatting it again. This can be done either with the phone itself or another Android device, or using a computer with a card reader.
The menu of some phones allows you to format the SD card by selecting the appropriate item in the settings. If it is not there, you can reboot the phone, enter “Recovery” mode and format the file system of the card by selecting “Wipe cache partition”.
Important: errors when working with the device in “Recovery” mode can lead to the loss of all data and even inoperability of the OS. Therefore, inexperienced users should not use this method.
It is easier and safer to format flash drives on a computer. To do this, you need a card reader and a formatting program (standard, built into the OS, or any other). You need to remove the flash drive from the device, insert it into the card reader and format it in exFAT or FAT32 format. After formatting, Android should begin to “see” the flash drive. If this does not happen, the problem is more serious.
The memory card has failed
Flash memory has a limited number of read-write cycles. In addition, the device may be damaged due to microcracks on the board or under the influence of static voltage. In this case, after installation in the card reader, the computer does not detect the flash drive. It is also not readable on other devices.
It is impossible to restore a damaged memory card or the data on it. This cannot be done either from the Android device itself, or by connecting it to the computer as a flash drive via USB, or from the computer via a card reader. All that remains is to purchase a new flash card compatible with your device.
Important: sometimes, due to a board malfunction, phones and tablets can “burn” memory cards. Therefore, if a short time after replacing the flash drive it fails again, it is necessary to diagnose the Android device.
Memory card and Android devices are not compatible
A smartphone or tablet may not see the flash card if it is simply not designed to work with modern storage media. When there is a suspicion that the card does not correspond to a tablet or phone, then you should try to read it on a computer with an adapter for memory cards. If the gadget does not see the card, but the computer does, the reason is incompatibility.
All gadgets have restrictions on the maximum size of the memory card: 16 GB, 32 GB, 64 GB, 128 GB. This happens if, for example, you bought a 64 GB card, but the limits of your smartphone (tablet) are 32 GB.
Another option is that the flash drive is made to a technical specification that is unknown to your device. In this case, the gadget does not recognize it. Therefore, before buying a memory card, you need to study the documentation of your tablet or phone to buy an SD card of the appropriate size and type.
In addition to incompatibility, device damage or software failure may occur. In this case, the computer will also see the flash card, but the phone (tablet) will not.
Software error
In this case, the gadget either does not see the memory card at all, or certain programs do not see it. If you know - the card is empty, although it shows that the space is occupied, the problem is in the settings or performance of the OS and software of the phone (tablet). If Android does not see the SD card in applications, but does see it in recovery, try looking at the settings first. It is possible that the save path for applications is not set to the card, but to the internal memory. Fix it.
Another solution when only one application does not see the card is to reinstall or update it, and also check its own settings.
Important: often the phone OS begins to see the inserted card only after a reboot. If the flash card is not visible without rebooting, and then works fine, nothing else should be done.
When the above does not help, you should try updating the firmware of your tablet (phone). Often, after updating the OS to a newer version, the device begins to work correctly with the SD card.
Broken SD card slot
If a smartphone does not see a flash drive installed from another smartphone, and it meets the technical requirements of the device, the problem is in the smartphone itself. In this case, you can try to insert the card so that the contacts in the phone fit tightly to its tracks. To do this, you should try to clean and bend them a little. If the problem is not with the contacts, but with damage to the controller or card slot, all that remains is to send the gadget for repair or replace it with a new one.
For example, the HTC srochnyi-remont.ru workshop repairs all models of this manufacturer, as well as other brands. Look for a service center for your phone in your city.

Recovering a MicroSD memory card
The problem of MicroSD recovery is now more popular than ever, and is in great demand. Flash drives often break, but half the trouble is when it just breaks; the second “bad” part is that the information on it is also lost, which is undesirable. This is why questions are often asked on the Internet about how to even get information from a broken flash drive. 
The problems with this can be very diverse, some simply cannot recover the media, while others produce errors. Especially for recovery, there are special programs for restoring MicroSD cards. The user only needs to point to them.
1. MicroSD recovery programs
ColdRecovery does an excellent job of recovering photos, audio recordings, videos, and more. The program cannot recover regular files, so it is suitable only for those media that are used on cameras, phones and music players.How to use CardRecovery:
