Show on the Piggy monitor the micro sd connection. Android does not see the microSD memory card (flash drive)

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 hosted on this media is lost.

Why does the phone not see a memory card or USB flash drive that was working and being read properly yesterday? How to solve the problem on your own?

How to find the culprit

The source of the problem can be software and hardware errors both in the memory card itself (flash drive) and in the phone.

The reason is most likely in the card (flash drive) if:

It is not defined or defined, but not read by different devices.
It stopped being read immediately after being used on another device.
It has visible mechanical damage.
When the card is inserted into the slot (flash drive is connected), 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 detect but does not read any microSD card or flash drive.
When you install any card or connect any flash drive, it turns off, reboots or freezes.
The card slot (USB connector) has visible mechanical damage.
The failure was immediately preceded by any actions with the phone: installing applications, updating the firmware, antivirus scanning, resetting to factory settings, etc. Or incidents - blows, falling to the floor, etc.

When connecting flash drives with a full-size Type A USB connector to mobile gadgets, OTG cables and adapters are used, which are also often the causes of such situations.

Unfortunately, in many cases there are no obvious signs of the “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 reads all drives correctly, except for this one.

Because of what memory cards and flash drives are 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 have another one - education. oxide film on a surface 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 of a software 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 under Windows control and formatted to NTFS. Or she was in another smartphone and was formatted in exFat. In order for removable media to be read normally on any android versions, it should be formatted in FAT32.

The removable drive is infected with malware. The reason for the lack of access to it may be blocked by the antivirus that runs on the phone, or the actions of the malware itself.
The file system of the memory card or flash drive is damaged. The reasons are incorrect shutdown (for example, during recording), use on a faulty device (including connection to a faulty reader or adapter), unstable power supply, viruses, and so on.

Why the phone does not detect or read memory cards and flash drives

Causes on the part of the phone can also be hardware and 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 will most likely not recognize any SD card. And if the USB socket is broken on it, 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 any drive is installed in the slot, the phone freezes tightly, reboots, etc. Or a seemingly undamaged slot and a working card are not detected in the system in any way. Or are defined 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) occur only when connected together with a failed device.

Software reasons:

Incompatibility with microSD cards of a certain type or volume (lack of driver). In such cases, maps may be detected, but incorrectly and without access.
Crash in the operating system. Manifested by errors "SD card does not work" and other similar ones. Either removable media is not defined at all.
Install blocking apps.
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 service center or buying a new drive). If the previous action did not give the desired result, go to the next one. Recommendations for flashing devices are given more for reference. 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) are easy to fix with your own hands if you know how to use a soldering iron.
Clean the contact group of the memory card with an eraser or alcohol. This will remove the oxide layer from their surface and restore signal transmission.

Connect the media to the computer (if you are using a reader or adapter, make sure they work). 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 HDD PC.
Scan the media with an antivirus program.
Check it for file system errors. To do this, you can use the standard Windows tool (the chkdsk utility, which is used to find and fix disk errors): open the properties of the drive in Explorer, go to the "Tools" tab and click "Check". In the next box, check "Automatically fix system errors" (by the way, in Windows 10, auto-correction of errors is enabled by default, so this box does not appear).

If the probable cause is a failure of the firmware (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, no data will remain on it. In addition, in case of unsuccessful firmware, the drive may completely fail.

If the phone is the likely culprit:

Check for mechanical damage to the memory card slot or USB socket.
If slot for a long time has not been used, 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 that it is normally defined, the reason is in something from the disabled one.
Scan your phone for malware infection.
Remove apps that you installed shortly before the crash.
Temporarily uninstall 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.

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 internal memory devices. 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 the file system of the card by selecting the “Wipe cache partition” item.

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 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). 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.

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

Why does the phone not see the MicroSD flash drive?

Needless to say, there can be any number of reasons for such failures. Here are software failures of the system itself, and the 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 may look twofold. On the one hand, this may concern the newly purchased new card, and on the other hand, the problem may lie in the fact 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 that stated in the device's support. So in this case, the map will not be determined.

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

If there are problems with already installed card memory, no matter how it sounds, the cause may be the usual contamination of the device, say, dust ingress. Agree, not every user constantly cleans his phone.

Here the way out is the simplest: pull the card out of the phone, wipe the contacts on the flash drive itself and on the card reader, and then insert it again. By the way, this option is also suitable for new cards. Well, you never know, the contacts just didn't work. Therefore, do not rush to run to the service center or throw away the card you just bought.

Using Recovery Mode

If the simplest manipulations with contacts do not help, you can use the special recovery mode (Recovery) provided in any Android device, although you can start with 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 another combination himself. That's not the point. After starting the device, a special service menu, where you need to select the Wipe cache partition item, after which you just need to reboot the device. If after that the phone does not see the MicroSD, we proceed to more effective measures. They will be radically different from the previous steps.

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

Well, firstly, it is worth noting the generally exceptional situation when both the computer and the phone do not see the MicroSD flash drive. It's already worse. On the phone, this problem is almost never fixed.

First you need to insert the card into another device or computer and make sure it works. If it is found, the problem is only with the phone or 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, for starters, you should use which in Windows is called quickly enough. You can use the combination Win + X and then select Disk Management, or enter the command diskmgmt.msc in the Run menu bar.

This method is good because absolutely all connected disk devices, even unformatted ones, will be displayed in the main window. It is very possible that the letter of the removable card, such as "F", is the same as the designation of the optical drive. We right-click on the map and select the command to change the letter.

However, after such an operation, a situation may also appear when the phone does not see the MicroSD flash drive. What to do, because it is already recognized on the computer? by the most simple option Correcting the situation will be partial or complete formatting of the media. However, full 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-clicking calls where and selects the format string. In a new window, you need to uncheck the quick format, and then specify the creation. But, in principle, FAT32 is installed by the system by default. Now it remains to confirm the start of the process and wait for its completion. After that, you can safely insert the card into the phone.

Restoring the MicroSD Card

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

First, you should again connect the card to a computer and laptop and carry out a standard check of the device for errors. We use the same "Explorer" with the subsequent transition to the properties menu. There we select the service section and with the obligatory indication of automatic error correction. Also, although not necessary, you can use a surface test with automatic recovery of bad sectors.

Another option involves fixing access to the memory card on computer terminals, as well as normalizing the 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 that, the problem should disappear.

Finally, if the card has minor physical damage, which is usually associated with microcontroller malfunctions, you will have to look for special formatting utilities, after knowing 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, a program is downloaded from the Internet for each card of a certain manufacturer in accordance with known parameters, after which formatting is performed.

Conclusion

If for some reason the removable device is not detected, you should not panic. First you need to determine the root cause of the failures. As practice shows, any of the proposed methods helps to solve the problem. If we talk specifically about phones, here, rather, cleaning the device from dirt, formatting the card or restoring performance, 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.

In spite of current version the Android operating platform in your smartphone, as well as regardless of its other technological indicators, it is possible that a situation will come when your gadget will no longer recognize the memory card.

Of course, the problem may be in the flash drive itself, which may simply burn out or its free space has been exhausted, but the problem may lie in the health of the flash reader. But, do not immediately panic and carry the phone to the nearest service center for help.

Ways to solve the problem

To start try restarting your smartphone. Perhaps the problem lies with the operating system itself. Traditionally, rebooting the OS helps fix minor system glitches that immediately disappear when a new session is loaded. If the reboot did not help, then the option with the system can be safely thrown aside;

Now you can try pull out the card directly, carefully wipe all contacts and put it in its original place. The problem may be in the banal clogging of the contact surface, due to which your Android the phone does not “see” the removable media;

You can also test your memory card on another smartphone. This will help to discard the option about the breakdown of your device. If another gadget can't see your cardmicroSD, - means the problem is in it;

In most cases, flash drive failure due to incorrect formatting. To restore the optimal functioning of the memory card, you need to reformat it using a PC (best of all - from a laptop). To perform this operation, you must:

Put your flash drive into the card reader;

Wait until map will not become available on the computer (perhaps, its status will be reflected as unformatted);

Right-click on the name of the built-in drive;

Check the box "Format";

The file system must be designated as FAT32, because the Android system does not see formats like NTFS;

Mark the item "Start";

Then disconnect the memory card from the PC system, insert it into your mobile gadget, and check whether it started working or not.

If it was not possible to solve the problem, then the problem is in the physical state of the card, and this problem can only be solved in a service center.

Problems with internal memory

In practice, there is another way to solve the problem when Androiddoes not see external memory devices. The failure could occur if the operating files responsible for optimal reading and playback of data from removable media are accidentally deleted.

In most rooted devices, the built-in media can break when an inexperienced user accidentally confirms the deletion of system files.

Of course you can try turning it off. device and turn it on again. If this does not help, then you should open access to the Recovery mode.

Operations in mode Recovery

With the gadget turned off, hold down the power button and volume down (as a rule, each manufacturer of mobile gadgets independently sets the combination of buttons);

In the special menu that appears on the display, click on the line Winecachepartition;

Reboot your device;

This method should solve problems with the maximum SD carrier.

If our article helped you solve the problem with a memory card, share it with in social networks with your friends.

Nowadays, it is much easier for users to store the information they need. It is absolutely not necessary to load the PC memory, since there are many third-party elements - flash drives, CDs and DVDs. Micro and miniSD, as well as regular SD, are also very popular.

Each of the proposed tools may malfunction. This manifests itself in the fact that as soon as the user removes the removable media directly from the mobile, camera and other device and inserts it into the PC connector, the computer simply cannot detect the SD.

There may be several reasons for this development. In some cases, this is the result of the action of viruses. Also, banal errors may occur during the user's work. Often the reason lies directly in the inoperability of removable media.

Species diversity of SD cards

It is worth paying attention to the most common causes of problems. But before that, it is worth finding out exactly what types of flash cards exist. Almost all users confuse one card with another. Manufacturers have developed several types of SD.

There are special elements for mobile devices. There are also cards for photo and video equipment. So for everyone separate species devices provide their own tools. This is due to the different requirements for the amount of stored information and the speed of operation.

microSD cards are very popular. Such elements are inserted into mobile devices, tablets and players. With the help of these objects, it is possible to significantly increase the memory. This makes it possible to save much more audio and video recordings, photos.

Complete with such devices, users are encouraged to purchase special adapters. With their help, you can connect SD cards to a laptop. Not so relevant, but still often used - miniSD. These assistants are also suitable for portable equipment.

SD cards are excellent devices that have free memory from 8 MB to 2 TB. Such a large amount of size is necessary for users for DVRs, cameras. At the same time, the cards are able to function at speed with excellent performance.

Features in the process of working with flash cards

Each such element contains information about the speed of the object and the class of the instrument. When selecting a card, it is necessary to take into account which class is required for a particular device. You also need to pick up a special adapter. It can be several assistants in one set.

In many "weak" personal computers, developers have provided for the presence of built-in card readers. But these assistants are not able to recognize the new types of SDHC cards being used. But even in this situation there is a solution. Users will need to purchase a card reader that will connect to a regular USB port. Such connectors resemble standard flash drives.

Reasons for not recognizing flash drives

In some cases, just one drive letter can prevent the detection of removable drives, including flash drives, external hard drives. Anyone hard drive and flash drives, the letter F can be spelled out. For this reason, it is impossible to recognize the connected device.

To quickly fix this, you will need to go to the panel to manage all disks. This path for different versions operating system is different. If Windows 8 is installed, then you need to simultaneously click on the Win + X buttons and hold down. In the context menu that appears, select Disk Management.

For OS version 7, you need to click on Win and simultaneously press R. Next, you need to enter a simple command "diskmgmt.msc". Immediately after that, a new window will open. All disks and other connected devices will appear in it. You can also see formatted devices.

The desired flash card will be shown in the same list. Immediately after that, you should change the original version of the letter to a unique version. It is necessary to make adjustments to the context menu that appears immediately after right-clicking on the desired object for storing data. Next, we carry out formatting, during which the drive will be completely cleared of information.

The next common cause is the lack of drivers. Even if the user is working with a new device and is constantly updating necessary components, then this is not a guarantee that the device will work in normal mode.

If by chance it was discovered that at least one driver was missing, then you can use special assistants. Thanks to the utilities, it is possible to detect a package of the necessary drivers for each device. It is enough to enter a request on the network to search for a utility to update drivers.

Once these actions are implemented, it will be possible to immediately proceed to the next stage. In some cases, users try to insert an SD card into any device. Only after that we connect a mobile device, a camera with a flash card directly to a personal computer. To do this, use a special USB cable.

In some cases, users try not to use additional utilities. Only owners of new versions of the operating system can afford it. Windows systems. Then the process of installing the necessary drivers and the subsequent configuration of the PC parameters is performed without user intervention.

In other cases, the very first time you connect a device to a special port, you will need to download an additional software. There are unique drivers for all device models. Users need to pick them up and install them. Only after that the used memory card will be visible on any computer.

So users can solve the problem in several ways. Rodin of the proposed options without fail will be effective. It is only necessary to carry out all the steps correctly to ensure an excellent result.
