The SD card in the phone does not work. Why doesn't the phone see the SD memory card or USB flash drive? What to do

Modern phones often have a fairly small amount of internal memory, and that is why owners have to buy a memory card with the required number of gigabytes. There they store photos and videos taken, all kinds of working documents and study materials. It’s not even worth mentioning the amount of music that fits on one standard 4 gigabyte memory card. Of course, in this case, a situation where the phone no longer sees the memory card can bring many minutes of mental anxiety.

But don’t rush headlong to look for the nearest service center or open the online store catalog to look for a replacement for the breakdown. Perhaps the situation can be resolved on our own. The first step is to rule out the possibility of a problem with a loose contact. To do this, the memory card is removed from the phone and then returned to its original position.

Next, you need to restart your phone. Since it is quite possible that it was just a software glitch. Also, older phones may have a problem with large-capacity memory cards or devices with increased access speed (SDHC), so when purchasing them, check with the seller about compatibility with your phone.

If the situation (the phone still does not see the memory card) has not changed, then you will definitely need a card reader. So, you can insert a microSD or miniSD card into the card reader, and it into the USB port of the computer. After this, you need to find “My Computer” on the desktop; if a line with the name of the memory card appears there, then right-click its context menu and select the “Properties” line.

In the window that appears, go to the “Service” tab, and there we look for the “Check disk for errors” item and click the “Run scan” button (here in the settings you should set the “Scan and repair damaged sectors” option). After completing the check, you need to return the memory card to the phone and make sure that everything is in order.

If restoring damaged sectors did not help, and the phone does not read the memory card, then you can turn to drastic methods and format it. In this case, all the data contained on the flash drive will be lost (if the microSD was opened on the computer, then you should transfer the information to the hard drive). Just use the card reader again and select the “Format” line in the context menu of the flash drive.

The main reasons why the phone does not see the memory card

Alas, if you have done all this, but the media still does not become visible, your path will have to go to a certified service center. Only a master will be able to determine what exactly happened, as well as what to do in a particular case.

Most often this happens precisely because the media and device are not fully compatible. Each manufacturer has its own standards for internal phone card readers and memory card contacts. Therefore, for example, Nokia phones do not work very well with Apacer carriers. Therefore, when purchasing, we repeat, be sure to check whether they will be compatible.

In addition, a fairly common cause of this incident may be simple damage to the media. Do not expose it to adverse physical influences such as sudden changes in temperature, excessive pressure or contact with liquids.

Quite often, owners of Android devices encounter an unpleasant problem when the phone has a MicroSD. What to do in this case, what methods to solve the problem to apply? First you need to determine the root cause and analyze possible situations.

Why doesn't my phone see the MicroSD flash drive?

It goes without saying that there can be any number of reasons for such failures. Here there are software failures of the system itself, and a banal lack of contact between the memory card and the card reader, and violations in the file system of the USB drive, and even physical damage.

However, the situation can look two ways. On the one hand, this may concern a new card that you just purchased, but on the other hand, the problem may be that over time the phone has stopped seeing the MicroSD flash drive. What to do in this case will now be considered.

By the way, the issue of compatibility between the card and the phone itself will not be discussed here. This is worth paying attention to separately, since outdated gadgets are not able to detect the latest generation SD cards. Moreover, it may be that the card’s memory is larger than what is stated in the device’s support. So in this case the card will not be detected.

The phone does not see the MicroSD flash drive: what to do first?

If problems arise with an already installed memory card, no matter how it sounds, the cause may be ordinary contamination of the device, say, dust. Agree, not every user constantly cleans their phone.

Here the solution is the simplest: remove the card from the phone, wipe the contacts on the flash drive itself and on the card reader, and then reinsert it. By the way, this option is also suitable for new cards. Well, you never know, the contacts simply didn’t work. Therefore, do not rush to run to the service center or throw away the card you just purchased.

Using Recovery Mode

If simple manipulations with contacts do not help, you can use the special Recovery mode provided in any Android device, although you can first perform a normal reboot.

To access the mode we need, we use the simultaneous holding of the power and volume down buttons. This is the most common option. But, in principle, each manufacturer can prescribe a different combination. That's not the point. After the device starts, a special service menu will appear, where you need to select the Wipe cache partition item, after which you simply reboot the device. If even after this the phone does not see MicroSD, we move on to more effective measures. They will be radically different from the previous steps.

Problems with the MicroSD card on the computer: what can you do?

Well, firstly, it is worth noting a generally exceptional situation when both the computer and the phone do not see the MicroSD flash drive. This is already worse. This problem is almost never fixed on a phone.

First, you should insert the card into another device or computer and make sure it works. If it is detected, the problem is only with the phone or the drive names on the computer. If the card is not detected, the problem is either with the file system or with the memory card itself.

So, first you should use which is called quickly enough in Windows. You can use the Win + X combination and then select Disk Management, or enter the diskmgmt.msc command in the Run menu bar field.

This method is good because absolutely all connected disk devices, even unformatted ones, will be displayed in the main window. It is quite possible that the letter of the removable card, for example “F”, matches the designation of the optical drive. Right-click on the map and select the command to change the letter.

However, after such an operation, a situation may also arise when the phone does not see the MicroSD flash drive. What should I do, since it is already recognized on the computer? The easiest way to correct the situation is to partially or completely format the media. However, complete formatting with deleting all data and re-creating the file system still looks preferable.

It can be produced either here or from the standard “Explorer”. In both cases, right-click calls up where and selects the formatting line. In the new window, you need to uncheck quick formatting, and then specify creation. But, in principle, FAT32 is installed by the system by default. Now all that remains is to confirm the start of the process and wait for it to finish. After this, you can safely insert the card into your phone.

Restoring the MicroSD card

Now a few words about another situation when the phone does not see the MicroSD flash drive. What to do if it is detected on the computer, but not on the mobile gadget?

First, you should again connect the card to your computer or laptop and perform a standard check of the device for errors. We use the same “Explorer” and then go to the properties menu. There we select the service section and with the obligatory indication of automatic error correction. Also, although not required, you can use a surface test with automatic recovery of bad sectors.

Another option involves correcting access to the memory card specifically on computer terminals, as well as normalizing parameters and system registry keys in the HKLM branch. You should find the SYSTEM folder in the directory tree, in which the StorageDevicePolicies directory is located. On the right side, the defining parameter must be assigned a zero value (usually 0x00000000(0)). After this, the problem should disappear.

Finally, if the card has minor physical damage, which is usually associated with malfunctions of the microcontroller, you will have to look for special utilities for formatting, having first learned the VID and PID parameters. This can also be done using special programs, such as USBIDCheck, or by disassembling the card (where the data is indicated on the internal chip).

Then, for each card of a certain manufacturer, a program is downloaded from the Internet in accordance with known parameters, after which formatting is performed.

Conclusion

If for some reason the removable device is not detected, there is no need to panic. First you need to determine the root cause of the failure. As practice shows, any of the proposed methods helps solve the problem. If we talk specifically about phones, it’s more likely that cleaning the device from dirt, formatting the card, or restoring functionality, as described in the last version, is more suitable.

By the way, the issue of compatibility between the card and the phone itself was not considered here. This is worth paying attention to separately, since outdated gadgets are not able to detect the latest generation SD cards.

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

  1. 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.
  2. Then, using a card reader, you need to connect the memory card to a personal computer.
  3. Launch the program and, following the assistant's prompts, recover deleted data.
  4. 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, 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, of course, is 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:

1. Download the program. We launch and continue the actions with the “Next” button.

2. Select “Drive Letter” in the special section, and then select the device type “Camera brand and...”, where we check the required boxes next to them and specify the folder for data recovery. "Next".

3. Wait for completion and “Next”.4. We look at the list of recovered files. Check the box next to the ones you want to save. "Next" again. The restoration is complete.

PC Inspector Smart Recovery

The program is superior to the previous one in its functionality; it will restore all required, available file types. It can also work to restore fixed and removable hard drives. It's easy to use: 1. Loading Smart Recovery;2. In the start window, select the desired item, in our case it is “recovery of logical files”. 3. Select the required disk.

On the forums and the official website they write that this software is the most “comprehensive”, and it will restore most of the files intact. Users agree to this. To recover data using R-Studio, you need:1. Download R-Studio to your PC.

2. Select the “Drivers” section, where you will need to select the media from which the data will begin to be recovered. The Properties section should now start displaying the properties of the object being restored.

3. The next section “Folders” shows the folders, and the other “Contents” shows the data (files) of this folder. To restore them, you will need to click on the “Recovery” item.

Many professional users praise the program and its file recovery capabilities. There is only one way to check the functionality of file recovery from Easy Recovery: 1. Install it before downloading.

3. Click “Continue” again. Next, go to “Data Recovery”, and check the box under this item.4. “Continue” again. Now all that remains is to wait for the process of scanning all deleted files and compiling a list to complete. Each file can be recovered separately. Select it, right-click on it and select “Save as...”.

Flash Memory Toolkit

Functional file recovery program. It can perform a variety of functions, including testing and destroying any information, backing it up and obtaining additional data. To restore data, select the desired flash drive in the “Device” section, look for the “File Recovery” item on the left and follow the software instructions. This may happen so that the restoration of microSD using the programs provided above is not always successful.

2. Possible problems with MicroSD recovery

MicroSD not defined

It happens that the MicroSD card needs to be restored, but the PC simply does not see it. If this happens, there are three options to solve the problem at once: 1. If the flash drive is designated simply by a letter when connected. Then you need to open the “disk management” program, to call it you need to enter the command in a special execution field called up by the Win + R key combination, and enter the command diskmgmt.msc into it. Select the flash drive, and then click “Change the drive letter or path to it.” After which you will need to select any other letter of the alphabet and save the changes.
2. Lack of drivers. In some cases, a new PC may simply not have a special driver for the media. The solution is to install them. This is best done through off. Website. Of course, a special Driver Pack “DriverPack Solution” may be a good option. It can independently detect all devices connected to the PC and install or update drivers for it. This method is very attractive and convenient, since in this case there is a minimum of user actions.
3. The last option is simply to disconnect this flash drive and connect it to another device, which will give you a chance to read the files on it, or restore them using software.

The computer does not see files on the MicroSD flash drive

This means that the computer does not see the flash drive in its entirety, but only partially, that is, some files are there, others are not. Often, users immediately come to a simple conclusion - the problem is in the flash drive and it needs recovery, but the problems are most often much simpler. The solution to this popular problem is as follows: viruses, most often Trojans, need to be removed. Indeed, the Trojan may hide some or all files. Therefore, just turn on the flash drive in your PC and scan it with an antivirus.

3. MicroSD cards. Restoration from different manufacturers.

MicroSD Transcend recovery

For such cards, manufacturers have created their own original software for recovering lost files. The software is called RecoveRx. The provided software takes into account all the features of the map, and is also capable of performing a number of functions better than any other programs. RecoveRx can format the microSD and also set a password on it.

MicroSD Transcend Recovery

1. Naturally, download the program from the official website.2. Select the desired file types.3. Wait for the end of the process.

MicroSD Kingston recovery

The problem with this manufacturer is the Phison controllers. Which means that only low-level restoration can be done. Other methods simply will not bring results. 1. Determine the Product ID and Vendor ID parameters to find the best utility. This is done using another program - USBDeview. Open the software and find the required card on the disk. Right-click and select “html report: selected elements”. Scrolling the window below, we see the two required IDs.
2. Go to the website flashboot.ru/iflash, then enter special parameters into the required fields. As a result, you will see all the problems that have ever occurred with a specific card model. MicroSD Kingmax recoveryKingmax has acquired its own software. In general, there are two programs - one is PD-07 and U-Drive, and the other is Super Stick. Their use is as simple as possible: start - select a drive.

MicroSD Sandisk recovery

Users note that in case of any problems, Sandisk will only help with full formatting. After which the flash drive works as if it was just purchased. The program is also very easy to use.

MicroSD Smartbuy recovery

This is a very interesting manufacturer with “unique” flash cards. In the case of SmartBy, if the flash drive suddenly stops working, then after some time (a day, a week, a month, up to a year), it can independently start working again. But if you don’t want to wait, you can try to restore it with special programs. There is a program called “DiskInternals Uneraser” specifically for such flash drives. The application looks like a regular folder. Select the desired media and click on the “Recovery” button, also known as “Recovery”, you can restore files at the end of the process.

MicroSD Qumo recovery

Qumo flash drives are notorious for stopping working out of the blue. They just don’t work anymore and there is almost nothing concrete to identify signs of their “life.” Some experienced users suggest using “R-Studio” or “CardRecovery” programs for Qumo flash drives. But this may not always be effective. MicroSD A-Data recovery In this case, little helps. Only “Paragon Partition Manager Free” works most effectively with flash drives of this format. First, the program will ask for formatting, and then create a new partition.

MicroSD Oltramax recovery

For them, regular full formatting using a special SD Card Formatter is best.

4. Restoring damaged MicroSD

It happens that when using the drive, an alarming message “Memory card is damaged” or something else may appear on your screen. The following programs will come to the rescue:

Smart Data Recovery – will help you select the media and click the “Find” button, after which it will search for the necessary files that can be recovered.


- Recuva – after launch, click “Analysis” and wait for the process to complete.
- BadCopyPro – select Memory card, and click “next” twice.
The same operations can be performed on a tablet or phone on the Android platform. Other applications will come to the rescue here:

GT Recovery for Android – select the desired item in the program and wait for completion;

-Wondershare Dr. Fone for Android – launch the program, select the required files.

5. Prevention

It is best to start using the flash drive correctly so that no bad problems occur with it. Here are some tips that will help you avoid breakdowns:1. Try not to drop the flash drive, hit it, bend it, or generally subject it to harsh physical impact.2. Avoid various types of radiation, including X-ray machines and exposure to direct sunlight.3. Do not touch the contacts with your fingers and try to keep them closed at all times.4. From time to time, completely defragment the flash drive and use it as often as possible - flash drives do not like to sit idle.5. Create backup copies of the flash drive so that in case of malfunctions you can restore it.6. Leave free space on your storage device.

7. If the card is installed in a smartphone, tablet, or speaker, try to remove it from there less often.

In a phone, a memory card is an important accessory that helps unlock the potential of the gadget. Thanks to it, users do not worry about the amount of free space on the device; they download tens of gigabytes of data, photos, videos and movies that take up a lot of space. However, flash drives sometimes fail for various reasons. In this article we will help you find out why your phone doesn’t see the memory card and look at options for solving the problem.

The main reasons why the phone does not see the memory card

The flash drive may not work for one or more reasons:

  • mechanical damage to the storage device;
  • incorrect file system formats;
  • incompatibility with smartphone;
  • poor connection on the contacts;
  • the cable tracks are worn out;
  • incorrect settings;
  • reading failures.

The reasons and instructions are relevant for all phone models with flash drive support, so they will especially help those who have important data on the card that needs to be restored. However, remember: it is not always possible to get removable media to work. It happens that it completely fails, so we will look in detail at the symptoms of a particular problem.

What to do if the phone does not see the memory card?

To begin with, it should be said that sometimes this is a software bug that can be easily fixed by rebooting the device. But if not, no problem! Most of the problems that cause the phone to stop seeing the memory card can be solved. Let's look at each of them step by step.

Reason #1. Breaking

A flash drive can fail due to mechanical damage, exposure to extreme heat or cold, or water ingress. As a result, it will no longer be detected on any device, even through a card reader.

Alas, nothing can be done; memory cards cannot be restored. Therefore, all that remains is to buy a new one and protect it from factors that can cause irreparable harm to it. Before purchasing, make sure it is compatible with your device and test it just in case.

Attention! If the damaged memory card was under warranty and there are no signs of mechanical damage, then return it to the store. If the cause of the failure is internal, you will be given a new data storage.

Reason #2. File system error

Sometimes the file table crashes, so the flash drive is not recognized. It also happens that its formatting or failure breaks the file system.

There are several ways to correct the situation, for example, through recovery.

  1. Reboot the device in Recovery mode (read on the Internet about how to do this specifically for your phone).
  2. Select the “Wipe cache partition” menu, which will launch the card formatting service in FAT32. It is very compatible with Android devices.

Attention! Make sure that you are cleaning the flash drive and do not confuse it with permanent memory, otherwise you will delete everything from the phone. Don't format this way unless you're sure about it.

Let's look at a safer method, which is done using a PC.

After this, it will be formatted and recognized by the device again.

There is also an option to try low-level formatting, but this is not always possible. Check out the special software for this on the SD card manufacturer's website.

Reason #3. Incompatibility

Most often it appears in the first minutes of installing a storage device. Before purchasing, you need to check whether the flash drive is compatible with the gadget, since it may not accept storage above a certain volume. There are also special SD cards that, for design reasons, are not suitable for a phone.

If you have already made a purchase, but it does not function, then try to exchange it or trade it in, provided that it is in perfect condition. Instead, choose a flash card that is compatible with your smartphone.

Reason #4. Sent contacts

Sometimes, after shaking or improper installation, the contacts come off and the mobile phone stops accepting the flash drive. Fortunately, this is quickly resolved. Just take it out of the tray, blow it out and then put it back in place. Reboot your phone and everything will work.

Reason #5. Wear of tracks and contacts

Over time, the contacts on the SD flash drive are erased, so it fails. This is a natural process, especially if you often take it out and rearrange it in different gadgets. They will be replaced for a small amount, so it makes sense to pay for repairs if important data is left on the card or it is very expensive.

In addition, the tracks on the Android smartphone wear out. There is only one solution: take it for repairs. Replacement will not cost very much.

Reason #6. Errors in saving settings

Some applications occasionally fail to read or write anything to the SD card, while others work fine with it. It may seem so at first glance, but in fact these are incorrect settings of these programs. They are simply aimed at saving data to internal memory. Therefore, dig into the settings, find the corresponding menu and indicate there “save to SD card”, and not to the phone. For example, this can happen in the camera application when, after shooting, it places photos and videos on something other than a flash drive.

Reason #7. Reading failures

If the card is unstable, then it may have accumulated a certain number of errors that prevent it from performing tasks correctly. To check it for errors, do the following:

  • connect it to your desktop;
  • in “My Computer”, right-click on it and go to “Properties” - “Service”;
  • press the "Check" button.

Upon completion, the program will display a message about the result and automatically fix any bugs found.

Now you know the reasons why the smart device does not read MicroSD. Fixing them is not difficult, so you can quickly figure out the problem and start using the storage device.

A memory card (not to be confused with a flash drive) is the most common storage medium. It has long eclipsed CD and DVD media, and the popularity of the drive is only growing. Engineers manage to endow a small piece of plastic with such an impressive amount of memory that soon even the need for bulky HDDs will disappear.

Today standard cards SD, SDHC And SDXC used in the following gadgets:

  • smartphones;
  • tablets;
  • cameras;
  • cameras;
  • readers;
  • VR glasses;
  • players and more.

But sometimes incidents occur during operation: the computer does not see a memory card that has just been removed from a device, although it previously worked properly. What is the reason? Let's try to figure it out.

Types and standards of drives

First, let's look at the purpose and specifications of the cards, and also consider the dimensions. There are currently 3 different standards on the market:

  • miniSD;
  • microSD

What is this gradation for? It all depends on the speed of reading and processing data by the drive itself. Let's say a mobile phone or smartphone, as well as a portable player, does not need high memory performance. Here the main criterion is the minimum size of the flash drive (the term is not entirely correct, but familiar to the average person).

MicroSD

Cards of this form factor are popular among developers of portable electronic devices. Dimensions of 11x15 mm allow the memory to be used in any device. A small piece of PCB can significantly expand the total memory pool of any device up to 128 GB (or even 256, if the device supports such capacity).

MiniSD

This standard has long lost its former popularity, but is also used in portable electronics. It was pushed out of the market by a “competitor” in the form of microSD. The dimensions are 21.5x20 mm.

SD

Cards of this type with dimensions of 32x24 mm are used in the dominant part of devices that require a large amount of external fast memory. Main scope of application:

  • video cameras;
  • registrars;
  • professional and consumer photographic equipment.

Such cards have several generations, characterizing the maximum amount of stored information and speed when reading/writing:

  • SD 1.0 – 8 MB – 2 GB (almost never used);
  • SD 1.1 – up to 4 GB;
  • SDHC – up to 32 GB;
  • SDXC – up to 2 TB.

Other important selection characteristics

Volume isn't everything. There is also “class” - the minimum speed of reading and writing information. Now the most common type is “class 10”, i.e. data transfer speed of at least 10 MB/s. If you record video in 4K resolution, then purchasing “class 6” and even more so “class 4” is simply useless - the delays will be enormous.

The second point is adapters and adapters. You can insert microSD into a special SD adapter (may be included) and use such memory in everyday life, but the speed delay will immediately come back to haunt you.

Since the basics have been studied, we will figure out why the computer does not see the memory card. Consider the following reasons:

  • compatibility;
  • incorrect volume letter;
  • drivers.

Compatibility issues

All card readers, whether built into the PC or laptop case, or an external device operating via USB, are backward compatible. In other words, if it is designed to read data from SDHC cards, it will work with SD 1.0/1.1 without any problems. But you won’t be able to “make friends” with SDXC - the technology is different, although the card looks identical to the others.

The problem is solved quite simply. It is enough to have at least one working connector in use USB 3.0(version 2.0 does not have enough speed) and an external card reader, which is sold in any electronics store for a penny price.

Drive letter conflict

An SD card is the same disk, only solid-state. It is detected by the system like a HDD, SSD and DVD drive, i.e. receives its “letter”. Often registration is automatic and you won’t even notice it. The problem can occur in two cases:

  • 26 logical devices are connected to the PC (the number of letters of the alphabet);
  • The system refuses to register the drive on its own.

In the first case, you will have to disconnect at least one disk/drive/flash drive; there are no other solutions. In the second, everything is a little more complicated, but fixable. If you are sure that the card is fully functional and visible on other devices, but is not displayed on the working machine, do the following. Press the Win+R combination and enter the command “ diskmgmt.msc»

We get to the Disk Management Manager. All drives and other “letter” devices will be displayed here. It is typical that you will not see A and B, since these letters are reserved for Floppy drives. Even those units that are not formatted and not recognized by the system will be shown. Have you found your card (which it is advisable to rename first)? We do the following:

We change the letter to a unique one by right-clicking on the device and selecting the desired item in the context menu.

We format the card if it is new or does not contain any important data. If there is important information, dump it on a PC/laptop that can read the information. Formatting removes absolutely everything from the surface - remember this.

Don't forget to change the file system to NTFS (reads files larger than 4 GB) and rename the disk itself (this makes it easier to recognize).

Drivers

Another popular problem that is also being solved. Most often, it affects new equipment that was just purchased in a store, or you installed a new version of Windows, but did not install all the components. Often the kit includes an installation disk with all drivers and utilities. What to do if you didn’t put it in, or if there is no disk drive at all?

In this case, look at the name of your motherboard (PC) or laptop model. In the first case, we go to the website of the “mother” manufacturer and select the software necessary for our OS. In the second case, we do the same, but on the laptop manufacturer’s portal.

The second option is to open the device manager using Win + R and write “ devmgmt.msc».

We look for “USB controllers” and see a yellow warning triangle saying that the drivers are not installed. We update and use it. If the card reader is external, try looking for a driver for it - this can also solve the situation.

But if nothing saves you, then the time for the card has come.
