Does not read the microsd flash drive what to do. Why the phone does not see the SD or microSD memory card - all solutions

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. The problems of obtaining data from the DVR, 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

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 clogs up, there is no place left for recording service information of the OS, and the gadget loses performance and starts to freeze.

As a result, if the internal memory is low, it becomes impossible to work without a memory card.

To fix the problem, you need to establish the causes of the breakdown. Very often it turns out to eliminate the defect with one's own hand, without going to the workshop.

The phone does not see the flash drive due to formatting problems

The partition table can be damaged in 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 a card with a different file system is inserted, for example, from a camera. You can restore the card's performance by formatting it again. This can be done either by the phone itself or by another Android device, or by 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 the “Recovery” mode and format file system cards by selecting “Wipe cache partition”.

Important: errors when working with the device in the “Recovery” mode can lead to the loss of all data and even the inoperability of the OS. Therefore, inexperienced users should not adopt 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). It is necessary 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 start to “see” the flash drive. If this does not happen, the problem is more serious.

Memory card is out of order

Flash memory has a limited number of read-write cycles. In addition, the device may be damaged due to microcracks in the board or static electricity. In this case, after installation in the card reader, the computer does not detect the flash drive. It is also unreadable on other devices.

It is impossible to recover a damaged memory card or the data on it. This cannot be done either from the Android device itself, or by connecting it to a computer as a USB flash drive, or from a computer via a card reader. It remains only to purchase a new flash card that is compatible with your device.

Important: sometimes, due to a malfunction of the board, phones and tablets can “burn” memory cards. Therefore, if through a short time after replacing the flash drive, it will fail again, it is necessary to diagnose the android device.

Memory card and android devices are incompatible

A smartphone or tablet may not see a 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 it is worth trying to read it on a computer with a memory card adapter. If the gadget does not see the card, but the computer sees it, the reason is incompatibility.

All gadgets have limitations on the maximum memory card size: 16 GB, 32 GB, 64 GB, 128 GB. This happens if, for example, you bought a 64 GB card, and the limitations of a smartphone (tablet) are 32 GB.

Another option is that the flash drive is made according to a technical specification 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 in order to buy an SD card of the appropriate size and type.

In addition to incompatibility, the device may be damaged or a 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 that the card is empty, although it shows that the place is occupied, the problem is in the settings or performance of the OS and software of the phone (tablet). If the android does not see the SD card in applications, but sees it in recovery, try looking at the settings first. Perhaps for applications, the save path is set not to the card, but to the internal memory. Fix it.

Another solution when only one application does not see the map is to reinstall or update it, and also check its own settings.

Important: often the phone's OS starts to see the inserted card only after a reboot. If the flash card is not visible without a reboot, and then it works fine, nothing else should be done.

When the above does not help, it is worth trying to update the tablet (phone) firmware. Often after flashing the OS for more new version the device starts working correctly with the SD card.

Damaged SD card slot

If the smartphone does not see a flash drive installed from another smartphone, while it corresponds technical requirements devices, 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 snugly into its tracks. To do this, you should try to clean and bend them a little. If it's not about contacts, but about damage to the controller or card slot, it remains 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.

SD cards are a type of storage used in phones, cameras and camcorders. In some cases, a problem arises when the computer or card reader does not see the memory card of the camera or phone. The user inserts it into the appropriate port, but it doesn't show up in Explorer.

Check if the card is supported by the card reader

Users often confuse different types storage, on this moment there are only three of them: "microSD", "miniSD" and "SD". At the same time, a specific format is required for each device. requirements for speed, memory size are different.

Briefly about the types and characteristics of memory cards:

Working with a card reader, checking compatibility:

• microSD with the help of card readers can be used as an SD card. But it is not always recommended to do this (due to different data exchange rates);
• SD card readers are backwards compatible: i.e. if you take a device that reads SDHC, then it will read SD cards of 1 and 1.1 generations, but will not be able to read SDXC. Pay attention to which drives are compatible with the adapter.

Checking the flash card and card reader for serviceability

To check the flash drive for serviceability, just install it on another device. If there is another card of the same model, check if it is recognized by the computer. There are several reasons that affect the operation of a memory card: improper removal of the device, physical wear, or damage. In the first two cases, you can try to restore the media to working capacity using special low-level formatting utilities.

We use the SDFormatter program to recover a flash drive in SD, SDHC and SDXC formats:

If the problem lies in the card reader itself, then in this case you will need to contact the service center. If you need to use the drive immediately, purchase a special USB adapter equipped with a card reader, you can connect it to your laptop.

The problem can also occur due to incompatibility, at the moment there are several types of flash drives: SD with byte addressing and SDHC with sector-by-sector. To rule out incompatibility, it is better to use USB SD-MMC adapter. With it, you can use several types of memory cards.

Operating system errors

In some cases, a computer or laptop does not see the SD card due to errors in operation. operating system, we list common failures:

Viruses on the computer

The reason why the SD card is not detected may be the presence of viruses that can interfere with the USB ports. Install an antivirus program, such as Kaspersky Antivirus or Dr.Web Cureit and scan the system. If malicious files are found, it is recommended to delete them.

Important! To prevent deleting files from a flash drive, perform a backup.

Checking drivers

When MicroSD is not detected, you can use programs to detect outdated drivers and update them to the latest version. DriverPack Solution is a utility that allows you to check the system configuration and update drivers. Download the utility, install it on your PC and run it. After starting the program analyze the system and check if the drivers are up to date. Select the tab " Set up components automatically” and wait until the required files are installed.

Check if the card is defined on the computer

Check if the system was able to determine the drive:

• open the explorer through the shortcut " My computer» on the desktop;
• select menu " This computer"and expand the section" Devices and drives»;
• if a new disk appeared, the flash drive was determined.

Second way:

Computer hardware problems

If it does not open or is not detected when connecting the Micro SD through the adapter to the computer, it is worth checking the card reader for operability. First try insert into adapter a known working flash drive, if it is not detected, then reinstall the drivers on the card reader.

Checking the drivers:

File system conflict

In some cases, the flash drive may be detected, but it cannot be opened. The cause is a file system conflict or a corrupted file system on the media itself. If the data stored on the flash drive is not important, you can format the card to the NTFS file system:

Partition letter already in use assigned

This situation occurs when an SD card is connected to a computer, when the system assigns it the letter of an existing drive. Because of this, a crash occurs and the flash drive is not displayed in the explorer.

Instruction:

Why does the phone not see the memory card? To begin with, it is worth deciding on the type of problem and trying to solve it yourself. Although in this case it is easier for many people to contact the workshop so as not to waste their time.

We are talking about a small device for digital technology, allowing you to increase its memory. Such devices can be: mobile phone, computer, tablet, digital camera etc. Modern technology has a fairly large built-in memory, but only for basic tasks. Someone likes to watch movies on the phone, someone needs music on the phone. If the phone does not see the flash drive, what should I do in this case and how to fix this problem?

There are 3 main types:

MicroSD (11 x 15 mm). It is the most popular and widespread type. Micro SD are used mainly in mobile phones, but can also be used in other technical devices due to a special adapter. Thanks to the versatility microSD memory give the most preference.

MiniSD (21.5 x 20 mm). It is an obsolete type due to the greater popularity of other formats, it is used in portable technology.

SD (32 x 24 mm). It is used in the technique where it is fundamentally important fast speed data exchange and a large amount of information storage. This includes a camera, camcorder and similar equipment.

All of them come in different sizes of data storage, but SD is divided into 4 generations:

SD 1 (8MB-2GB).

SD 1.1 (up to 4 GB).

SDHC (up to 32 GB).

SDXC (up to 2 TB).

There are many storage media and adapters for them. Through the adapter, you can see a flash drive that has not been read before. It can also look like a USB flash drive.

Therefore, if the DVR does not see the memory card, then the matter may be in its type, so you just need to replace it. After all, video recorders need storage media with a high data exchange rate.

Phone: Solutions

If the phone does not see the memory card, what should I do in this case?

This means that the selected flash drive does not fit the phone model. If the phone does not see the drive, although it is inserted, this does not mean that it is suitable and should be opened. The fact is that each manufacturer of cellular devices and flash cards has its own characteristics. Most often, the instructions contain a list of SD cards that fit the device. The criterion for incompatibility can be size, data transfer speed, drive version, etc. If the smartphone does not see the memory card, then the problem may simply be their incompatibility.

You need to purchase a card that the cell phone supports, but if there is important data on the media, you can use other devices for data transfer, such as adapters and card readers.

How to be, there is no contact with the drive? Nothing is exactly the same, there are minimal errors everywhere, including production. This can happen over time. How to make the map visible? If the phone has stopped seeing the memory card for no apparent reason, then you just need to pull out and reinsert the drive. When doing this, it is important that the machine is turned off, otherwise the media data may be damaged.

The card has a bad sector. In this case, you should check the card for errors on the computer using the adapter. If it doesn't help, then format it. These actions are acceptable provided that the flash drive is visible to the computer.

Blocking on the card itself. Sometimes it may not open on the computer even because of such a trifle. With the help of programs, you can remove the lock, but in some cases it can be removed manually on the storage medium itself.

System glitch, crash or freeze. In this case, you need to restart the device.

If after all the manipulations the carrier stubbornly refuses to be detected and the phone does not read the memory card, you should take the drive to the master. Solve the problem yourself this case not worth it. In addition, damage may not be visible to the naked eye. It may also be that the flash drive is not displayed just after the repair, so you should check all this on the spot.

Laptop: Solutions

Why does the laptop not see the memory card? The computer can also be attributed to this issue - there are actually not so many main reasons. As with mobile, some causes can be fixed on your own.

The same name for a flash drive and other storage media. In this case, the flash card is not recognized as a separate drive, and crashes occur instead. If the memory card has the same letter in the name as the built-in logical drive on the computer, you should change the name of the flash drive. This can be done by standard means through the Disk Control Panel. How to get there depends on the operating system.

There are no required drivers to read. It happens that the computer is not equipped with the proper software. But it depends on how efficiently the machine will serve. Here you need to download drivers from the Internet, disk or other storage media.

The reason that the computer does not see the memory card may be physical damage to the computer itself, laptop or drive. Therefore, it is better to take it to a specialized center or to a master.

One possible reason is viruses. Here you need to install an antivirus and conduct a full diagnosis, followed by cleaning the system. It is not recommended to install several antiviruses, as there is a load on the system.

Card reader: solutions

Why does the card reader not see the memory card? A card reader is a device for writing, reading and formatting flash cards. The card reader may not work normally for some reason: these are either physical damage or incompatibility with the flash drive.

The device can be external or built-in. The names speak for themselves, and the possible reasons why the device does not see the SD card are the same for them. It is worth emphasizing that the card reader ignores the card in case of errors that may occur when formatting it on a computer. If he does not see the camera's memory card, then the matter may simply be incompatibility of the models.

Camera: Solutions

Why does the camera not see the memory card? What is the problem?

Blocked flash card. On the side of the drive there is a small prominent lever that you just need to move.

Very common cause, according to which the flash drive cannot be read, lies in the incompatibility of the amount of information on the card for this camera model. Only changing the card itself to another type will help here.

Banal physical damage. What to do if the problem is in the camera? It is best to take it to a diagnostic center. If the problem is in the flash drive, then it's wiser to just change the card.

Tablet: Solutions

Why does the tablet not see the memory card? All the above reasons also apply to the tablet (hanging, bad contacts, breakage, incorrect formatting, etc.). The same remains the way to solve them.

Conclusion

Above, all the main reasons why a flash drive does not function, and ways to solve these problems were considered. The PSP has not been considered here, since PSPs are not as popular and have similar problems to the computer. In addition to the methods described above, it is worth mentioning that flash drives can be restored using various programs. If the computer makes a flash drive detection sound, and the memory card is not visible, then the HDD Low Level Format Tool program can help in this case.

It is also worth considering that if the drive is readable on one system, then it is impossible to say for sure whether it will be viewed on another. If something does not work for unknown reasons, do not be upset. Sometimes you just need to be more careful with equipment and accessories for it. Then she won't stop working. Many problems can also be avoided by reading the operating instructions in advance.

Situations with damage to the memory card are quite common. This article will discuss in detail the issue of recovering a damaged drive using third-party programs.

The loss of SD performance can occur as a result of many reasons - this may be damage to the drive itself, or the result of a malfunction in the device on which the card is installed.

Why crashes may occur

There are several most common causes, due to which damage to the memory card may occur:

• physical damage;
• Availability beaten sectors;
• wrong extraction drive;
• failure in the operation of the device;
• unknown mistakes, leading to a malfunction in the SD.

In what cases is recovery possible?

physical breakdown The SD card may be connected directly to the chassis damage. It can crack, and the microcircuits inside are at risk of being damaged. The most common case is retainer loss lock. In addition, the interface controller may fail. In this case, restoring work and saving data, fortunately, is still possible.

The presence of broken memory cells is no less common. In this situation, the flash drive is not recognized by devices. This kind of failure manifests itself over time, because the drive memory has several read / write cycles. When they run out, the flash drive fails. It is possible to restore work using specialized software.

Other than that, there are bugs that cause the SD to crash. These errors include the following system notifications:

• the media is detected, but its size is 0 KB;
• is not detected, read or opened on any device.

Mistakes:

• insert the disc into the device;
• USB device not recognized;
• flash card is damaged;
• this device cannot be started (code 10);
• error when connecting a USB device (code 43).

Each case will require analysis to find the cause of the failure and recover the data.

Failure of the device is quite common. In this case, the card is recognized on another device. It is connected with connector damage on the gadget itself. In this case, the device itself will have to be repaired, and not the USB flash drive. The same applies to damage to the SD card on Android.

Incorrect extraction is primarily due to the inexperience of the user. If the card incorrectly extracted, the flash memory is damaged. Unfortunately, this error cannot be fixed. In this case, only buying a new SD will solve the problem.

Formatting with special programs

Some problems can be fixed by software that performs low-level formatting of the drive. The most popular are HDD LOW Format and SDformatter. They are also used when the micro SD is not formatted.

HDD LOW Format

An effective program that will help format SD. HDD LOW Format has in its arsenal special formatting algorithms that will help restore micro SD performance in a few mouse clicks.

Process:

SDformatter

SDformatter is a small free and functional utility that allows you to perform low-level formatting of a flash drive. Among other things, the program allows you not only to clear the card, but also recover bad sectors. The simple interface of SDformatter will allow even a novice user to cope with the task.

The process looks like in the following way:

Using iFlash

To restore a memory card, you can use a special online service iFlash. This resource is a database of flash devices with the most suitable utilities for them.

Search process the desired utility on the iFlash resource:

Kingmax (Super Stick and U-Drive)

To recover media from Kingmax, you will need the Super Stick and U-Drive utilities. The principle of operation for both programs is the same.

You can restore the drive in a few minutes:

• open one of the versions of the Super Stick or U-Drive utilities;
• then a window will open (the interface of both utilities is identical);
• click " update” and wait for the process to complete.

Sandisk (Formatter Silicon Power)

• install and open the program;
• in the utility window, select the module " Recovery” and wait for the end of the recovery process.

A-Data (Paragon Partition Manager Free)

For drives from A-Data, Paragon Partition Manager Free is best suited.

The drive recovery process using it looks like this:

• open the program and in the main window use the module " Format Partition»;
• then you need to create a new disk partition, for this we select " Create new partition».

There is another useful program - HDDScan, consider the process of working with it on the video:

other methods

If the above methods do not help or it is not possible to use them, you can try to restore the memory card using other tools.

Letter change disk:

Let's move on to installing the drivers. To do this, you will need DriverPack Solution to automatically install the necessary software. You can also do this action manually and download the driver package from a specialized site.

In addition to using programs and other tools, it is better to start check map on another device. If it is recognized, then the problem is hidden in your gadget (android phone, tablet, camera and computer).

How to check a memory card for performance

In case of failures and errors, it is worth checking the performance. To do this, you do not need to use special tools, standard operating system tools will suffice.

The check can be done as follows:

How to handle the SD card

To avoid data loss due to a memory card failure, you must adhere to set of rules when using it:

• try to keep the map in protected place, avoid getting water on the interface connector, drops and other troubles that can cause damage to the case;
• not worth it touch with hands to the contact connector;
• necessary defragment drive and use it as often as possible. If it is not used, then degradation of memory cells occurs over time;
• do not forget make copies files on a flash drive and transfer them to a PC;
• not worth keeping there are a large number of files on the card, you need to leave some free space;
• at extraction from PC, you must use Safely Remove.

In some cases, the phone does not see the microSD, but not all users know why this happens and how to fix the problem

Moreover, this problem is serious, since it does not allow access to all the information stored on the flash drive.

For users whose phone is a player, a device for Internet surfing, such a problem can be a serious problem.

The essence of the problem

How does it manifest this problem? How to understand that the phone really does not see the device? This is quite simple and becomes clear immediately after installing a memory card.

The device does not reflect that it was installed. At the same time, there is no memory card icon on the panel on the home screen, nor is removable media displayed in the Memory section in Settings.

Accordingly, in all directories of the phone (for example, Music, Gallery) there are no corresponding files, before .

Sometimes, after installing external media into the phone, the device does not immediately display a message about its installation, as it usually does.

Sometimes, while working with microSD, it may suddenly turn off, and a message will appear on the screen like "Memory card disabled".

In the most rare cases, the device reports damage to the memory card.

A problem can occur both on a new device and on an old one. And also as with old map memory, and with a new, empty media. Regardless, the causes are often the same for all cases.

Possible reasons

There are several reasons for this phenomenon. Conventionally, they can be divided into two large groups: problems with the phone and problems with the drive itself. The first group includes:

1. Direct damage to the memory card slot;
2. Other hardware problems in the device;
3. Problems with the functioning of the software, due to which the device does not see.

From the side of the memory card itself, there may be the following problems:

1. Device failure (especially when a previously working card suddenly ceases to be recognized or the device reports its malfunction, which is typical for old memory cards with great wear);
2. Physical damage to contacts on the card or other problems;
3. File system mismatch (some newer file systems don't "see" old phones, then it shows that the drive is missing).

Depending on the cause of the malfunction, certain methods of its elimination can be selected.

<Рис. 2 Слот>

elimination

There are several ways to deal with such problems. They are selected depending on the cause that caused the malfunction.

If this reason is not clear, then you will have to try several methods.

Working with hardware

<Рис. 3 Контакты карты памяти>

First of all, you need to check what exactly the problem is. Install another memory card in the device, and if it is detected, then the problem is in the drive itself.

If not, then the problem is most likely in the phone.

What can the user do in this case? It is recommended to clean the card slot from dust, as well as wipe the contacts on the carrier itself. You can do this with a cotton swab.

Most likely, this does not solve the problem, but sometimes it helps. However, if it turns out that the card slot is broken, then the only way is to replace it.

Recovery

<Рис. 4 Восстановление>

Each has a Recovery mode. Its launch will allow you to “roll back” all questionable settings to factory settings.

Thus, if the device previously saw cards, but now it does not, then this method can help.

1. To get started, perform a normal reboot of the device (not turning it off and on, but just rebooting);
2. If this does not help, proceed to recovery;
3. Hold down the power and volume down buttons at the same time and hold for up to 10 seconds (most often, access to the recovery function is opened in this way);
4. As soon as the device restarts, a special start menu will open in Windows;
5. Go to the Wipe cache partition item in it (you need to do this with the buttons or by clicking on the screen, depending on the device);
6. Reboot the machine (rebooting may take much longer than usual).

The map should now be defined. If this does not happen, then you will have to work with it on a computer.

Formatting

<Рис. 5 Форматирование>

Insert a memory card into a computer using an adapter. Open it through the "My Computer" section in order to make sure that the device is working.

If the computer does not see the drive, then such a memory card is faulty.

1. Press Win + R and wait until the Run window opens;
2. In it, write the command diskmgmt.msc;
3. A window should now open showing all memory devices - external, internal, formatted, not formatted;
4. If the letter designating the card matches the letter of, for example, an optical drive, etc., then you need to rename the card;
5. In rare cases, renaming may solve the problem;
6. If the problem is not solved in this way, then you need to completely format the card and create a new file system (of course, it is worth remembering that the data from the media must be copied before this);
7. You can format the device from Explorer;
8. Click on the memory card with the right mouse button;
9. A menu will open in which you need to select the line Format;
10. A window will open in which you need to remove the marker from the box next to the inscription "Quick Format";
11. Specify below that you want to create a format file system (most often this option is set by default);
12. Click OK;
13. Wait until the end of the process.

Then install the memory card in your phone. It should be successfully recognized. If this still does not happen, then it is possible that there is still a specific hardware malfunction in it.

Restoration of work

<Рис. 6 Восстановление через ПК>

Restoring the operation of a MicroSD card is a specific case when a media that was successfully recognized earlier suddenly ceases to be recognized by the same device.

At the same time, there was no damage to the carrier or phone, no changes in software phone number was not entered, etc.

Also this method can help when the phone says that "Unable to access memory card", "The memory card is damaged, etc.".

This method is quite effective, but only for older cards. And only on condition that they worked properly before. For new cards, this method is useless.

1. Connect the memory card to a PC or laptop to make sure it is working;
2. Open Explorer and right-click on the map;
3. Select Properties from the drop down menu;
4. Go to the Service tab;
5. Run Check disk, having previously indicated the need for automatic correction of detected errors and malfunctions;
6. In the same section, you can Surface test with automatic recovery of bad sectors (although this is not necessary).

A more complex option is troubleshooting by working in the HKLM branch. This is done as follows:

1. Find the SYSTEM directory in the folder tree;
2. In it, open the StorageDevicePolicies section;
3. In the right part of the window, the parameters that need to be changed will appear;
4. Assign a zero value to the defining parameter (write the number zero in brackets in the combination 0x00000000(1)).

Now the card should interact normally with the phone.

File system

<Рис. 7 Файловая система>

There are microSD HC and microSD XC memory cards. The second option is typical for cards with a capacity of more than 32 GB.

They have a different file system, which has its own advantages (for example, recording speed and length of recording segments), but is not recognized by all phones, tablets and other devices.

Thus, some phones are simply not designed to support cards larger than 32 GB. Changing the file system in this case is almost impossible without special skills.

However, it is worth remembering that the type (HC or XC) of the card is written directly on it, so it is important to choose the right one.

WHAT TO DO IF THE ANDROID (PHONE) DOES NOT SEE THE MEMORY CARD?

The phone does not see the MicroSD flash drive: what to do, how to fix it?
