The micro SD card helps to significantly increase the memory capacity of your Android device. Therefore, if Android does not see the microSD flash drive, users immediately need to understand the causes of the malfunction and eliminate negative factors.
This article is suitable for all brands that produce phones on Android 9/8/7/6: Samsung, HTC, Lenovo, LG, Sony, ZTE, Huawei, Meizu, Fly, Alcatel, Xiaomi, Nokia and others. We are not responsible for your actions.
Memory card problems
If Android does not see the memory card, then the cause of the problem may be on the side of the device itself or in the operation of the flash drive. Start diagnostics from an external drive. Common causes of failure include:
- Wrong file system (for example, NTFS or ExFat instead of Fat32).
- Formatting errors, file system failures.
- Incompatibility of the card and phone, unsupported volume (the device cannot work with cards larger than 16 GB, and you put a flash drive of 32 GB, 64 GB or 128 GB).
- Hardware problems of the memory card, physical damage to the contacts.
If the card from the camera or from the DVR is not readable when installed in the phone, then the first thing to do is to make sure that the mobile device supports this format and volume.
An incompatibility problem can only be corrected by replacing the drive with a suitable one. It is much easier to deal with errors in the file system (or the wrong file system). After formatting, the card will be detected without rebooting and other unnecessary actions:
Increase Formatting will delete all data on the memory card. If this is critical, save them to your computer before cleaning the drive, and after changing the file system, put them back on the card.
Phone problems
If the memory card is compatible with the phone, the file system is in a format that is suitable for Android, there is no hardware damage, then the reasons should be sought in the smartphone. If the smartphone does not see a flash drive installed from another smartphone, but the computer does, then the following factors can affect this:
- Incorrect drive installation.
- Damaged/dirty memory card slot.
- Android software glitch.
Try to pull out the memory card, and install it again, making sure that the slot is working. If you see that the contacts are dirty, clean them with a regular eraser or a damp cloth. If cleaning doesn't help, chances are the contacts are loose or damaged. Repairing them yourself is problematic, usually a component replacement is required.
If the device in Recovery sees a flash drive, while Android does not see the SD card in applications, although it shows that the place is occupied, then the cause of the problem should be sought in the system. If the error occurred due to a system failure, restarting the device will help fix it.
Increase Another solution is to reinstall the problematic application or transfer from internal memory to microSD. What to do for this:
- Open settings.
- Go to the "Applications" section.
- Select the application that is having problems.
- Click Move to SD Card.
Increase If difficulties with determining the external drive arose after flashing the device, you should reflash it again using the official Android build from the manufacturer. You can get by with a less radical method and simply reset the settings through the Android interface or the Recovery Menu.
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
Often users confuse different types of drives, at the 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 the operating system, we will 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:
A flash card is the most functional and popular storage medium in modern times. CDs have their positive aspects, but the amount of memory, ease of use and other factors are on the side of the flash drive.
You can also connect a USB flash drive to an Android smartphone, and even the cost today is on the side of the memory card, because cheap options will cost only a couple of times more than DVD-RW.
Only it's much easier to disable or lose a memory card
It happens that a person removes this storage medium from his own smartphone or digital camera, but the computer does not open it. This is due to virus infection, software failures, and breakdown of the device itself. In such a situation, you need to restore the micro flash drive by changing the partition letter or in other ways.
VARIETY OF DEVICES OF THIS TYPE
Before you restore a memory card, you should familiarize yourself with the varieties of this small but useful detail. People are not very versed in this issue, which also brings problems. Today, three types of SD devices are produced: micro, mini, SD.
It would seem, why divide one species into three more additional ones. But this is a logical decision, because SD is used in various technologies: camcorders, video recorders, smartphones, mp3 players, etc. Gadgets differ in size and requirements for the power and memory of the device. Therefore, there are three subspecies, which are worth familiarizing yourself with in more detail:
- microSD. The micro SD memory card, due to its format and storage capacity, is commonly used in smartphones, tablets and media players.
A small device allows you to increase the memory of the gadget several times
- MiniSD is already slightly larger than micro. They are used on players and phones that are already 5-10 years old.
Today gave way to the previous option
- SD. This is the largest type that is used in photo and video equipment, in particular, in car recorders.
This option is distinguished by a large amount of memory and good speed.
Interestingly, the first option, if necessary, can be turned into a third one using an adapter. A micro card is inserted into this adapter, and then the design is inserted into devices that work with SD.
But this combination will not be able to fully replace the large version, because the speed of work will be too low
IMPORTANT NUANCES IN USING THE MEMORY CARD
- In addition to the amount of memory, speed is also indicated on the surface of the product (to be precise, the class). So, if a flash drive has this indicator equal to 10, then you can transfer data to the device at a speed of 10 MB per second. It is worth considering which class is necessary for the normal operation of the gadget.
- A memory card for a phone can be used as an SD card using an adapter. But, as already mentioned, it is not advised to do this because of the mismatch in the class of parts.
- The USB card reader for flash drives must be selected based on compatibility. When a gadget that opens SDHC is used, it will be able to work with SD 1 or 1.1, but it will not work to read SDXC.
Before buying devices for reading, you need to consider this characteristic.
Notebooks that are 7 years old or older can be equipped with standard card readers, but they cannot open SDHC. A card reader that connects via USB will help solve the problem. It costs a couple of hundred rubles. You can also use an otg cable (it will help you connect a micro sd card reader or a regular USB flash drive even to a smartphone).
SAME NAME OF SECTIONS
Let's return to the problem of device unreadability. A flash drive will not appear in the "My Computer" menu if it is given the name D, and the operating system section works with the same name.
fig.1. Unlocking a USB flash drive in such a situation is not difficult, for this the Disk Management menu opens (the combination of the Win and R keys and the command diskmgmt.msc)
A menu will appear on the screen, where the folder of each disk and devices connected via the USB input is displayed. When a memory card appears in this menu, you need to reanimate the flash drive in one of the following ways:
- Put a unique letter in the name, under which there are no sections yet.
fig.2. This is done by pressing RMB and then selecting the operation to change the letter
- Format the SD card using regular Windows tools or using special utilities. But it is worth considering that all files from the storage medium will disappear.
PROBLEM WITH DRIVERS
If you can connect the USB flash drive to the tablet, but not to the computer, then the necessary driver may not be available.
It happens that employees of hardware stores forget or do not have the desire to install the necessary components and sell computers like that. Included with the equipment should be disks with drivers, the installation of which will not take much time. If the computer is not new, or the disk with the "firewood" is lost, then the almighty Internet will help. In such a situation, the recovery of a micro sd flash drive will be limited only to the search and installation of components.
Special utilities are available on the Internet to analyze the operating system and find the necessary drivers, they will greatly simplify the task.
CONNECT WITH OTHER GADGETS
If the flash drive connects to the phone without problems, but it is not visible on the PC, then why not use this smartphone as a conductor and connect it directly to the computer (you can use the otg usb cable)
Most users rarely pull out a memory card to work with files through a computer.
The only concern is whether special software is needed for this purpose. In new versions of the operating system, you do not need to install anything else, Windows 7 and 8 automatically install device drivers. If desired, you can also use the program from the manufacturer (for example, NokiaPCSuite).
As you can see, restoring a microsd memory card is a simple matter, sometimes you need to install drivers, change the partition letter, or use third-party devices.
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 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 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 after 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 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 to a newer version, the device starts to work correctly with the SD card.
Damaged SD card slot
If the smartphone does not see a flash drive installed from another smartphone, while 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 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.
What to do if the phone does not see the memory card? Since I often get asked this and similar questions, I answered them all at once in this article. It will be useful for owners of cameras, Samsung, Lenovo phones, laptops - in general, all those devices that support a memory card and refuse to read data on the card.
First, some technical details describing the problem. Let's say, as a result of some manipulations, a mobile device (phone, tablet, smartphone) has ceased to identify a memory card (sd card) even through a card reader. All data is written to, bypassing the actual memory card. This is inconvenient as the sd card is not being used while the mobile device's memory is rapidly filling up. Productivity decreases accordingly.
So, the problem is described in detail, let's move on to diagnosing a phone, smartphone, tablet. Consider the most common reasons why phones do not see a memory card (flash drive) and how to fix this defect on your own using a card reader.
The phone does not see the sd card due to an incorrect file system format or a corrupted file table
Cause of the problem. 1) The file table on the sd card was damaged, the markup fell off. 2) You formatted the memory card yourself, as a result of which the phone stopped seeing the flash drive. 3) The file system of the sd card is unknown (used in another operating system)
How to fix. 1. Find out the size of your flash drive. If the microSD capacity is more than 32 Gb, most likely it is formatted in exFAT. Not all versions of Android support this file system.
2. A quick way to fix the problem is to reboot the phone in recovery mode and select the Wipe cache partition option in the Android service menu. This command will clean the contents of the sd card and format the media in the FAT32 file system - it is best suited for storing files on the phone.
Note. We would not advise inexperienced users to perform this procedure: if you mistakenly format the wrong partition, you will lose all data on the phone, including files in the internal memory.
3. A safer (and more convenient) method to format an SD card is through a computer. You will need a card reader and SD Formatter software. It will help you format your flash drive properly.
4. You can try low-level formatting - however, not all manufacturers offer their own software for this (check the memory card website).
The memory card of the phone (tablet) is out of order
Cause of the problem. As a result of mechanical / thermal damage incompatible with life, the phone stopped seeing the memory card or the sd card stopped working. As an option, the phone stopped detecting the flash drive, on other devices the card is also unreadable.
What to do. Alas, nothing can be done with a damaged sd card. All you have to do is purchase a new SD card that is compatible in size and specifications with your smartphone or tablet. The most unpleasant moment is that all the data that was stored on the memory card of an Android or iOS phone disappears completely. You can no longer restore them - neither by connecting a phone with a USB flash drive, nor through a card reader.
If the flash drive still has a warranty and it looks like new (no visible damage), try returning it to the store. If you're lucky, you'll get a brand new replacement card.
Check for bad blocks (bad sectors) via HDDScan
The problem is doubly unpleasant, because the phone was bought a month ago. I decided to transfer some audio-video files from my old phone. The new smartphone is j7, and the old one is also Samsung Galaxy Grand Neo… The data transfer went smoothly.
About a week later I looked at sd, and the map did not appear from my native "my files". I looked through, through the xplore file explorer. There all the folders were displayed, but were empty. But it's important to add this: there were music and some video in the phone's memory. So, they were displayed, but they were not "empty", but refused to be reproduced - "playback error". On an old phone with any sd and different ages, this has never happened, so what it was, but not this. And this recorded map can be read normally on the old phone, no problem.
For me, the main thing, as you understand, is the phone, is it the reason? Such refusals in reading for a month were twice with the internal memory, and four times with the seat. Reboot - and everything is fine. But this is not the norm for the phone?
Answer. There may be several reasons for this behavior.
Perhaps the cause of the error lies in your way of copying files from internal memory to external. Try different ways and test: for example, through a card reader on a PC, through a file manager on a phone, etc. Do you see the described reading error in all cases?
However, since you noted that there are no problems with other flash drives, then there may be a problem with the memory card. Who is the manufacturer, is the sd card compatible with your phone model? Read user reviews.
Third - update the software on the phone and.
The fourth is the SD Formatter utility. Try different file system formats.
1. Last chance to find the answer to my problem. The Samsung galaxy not 5 (china) phone uses only its internal memory, and the flash drive is not detected. What I just didn’t do ... And I put a checkmark, and inserted it into another mobile phone, formatted it this way and that - it doesn’t help.
2. On the phoneSamsung Galaxy A3 memory card not workingmicrosd16 GB. For almost half a year she was in the phone, all the photos from the camera were automatically saved on it. The memory card has not been removed since the time it was put into the slot once. I have been using the phone for almost a year. Previously, there was another card, with a volume of 8 GB.
R.SI moved the card to another phone - he does not see it either. And the computer doesn't recognize it either. What to do? On the flash drive are all children's photos and videos taken in six months.
Answer. If the smartphone or tablet does not see the flash drive, the problem may be in the application that does not save files to the right place. Check in the settings where the files are saved - to an sd card, flash drive or to the internal memory of a tablet / smartphone. For example, in the Android Gallery settings, you can change the storage location for photos.
Re-read the article. If all else fails, then perhaps the phone does not see the microsd memory card, because it is out of order.
The phone does not recognize the memory card. Transferred everything to internal memory. When the card is disconnected, all files are read, but not when connected. Now, when you turn off the SD card, the internal memory is also turned off and there is nowhere to save information. Tell me what can be done if the memory card is not readable (if possible).
Answer. Until this time, the memory card worked? Your phone may not support this card model.
If the sd card worked before, you may need to format your card - and it will be writable again.
The question is formulated incorrectly: you write that when the memory card is turned off, the files are read, while you say below that the internal memory is turned off. So where are the files being read from then?
1. The phone worked with a memory card. They sent a congratulatory video. Delete it and it reappears. I tried to reset my phone, but it didn't work. It didn't find any updates. After some manipulations in the recovery menu, he became different, found updates, downloaded and installed them. The firmware shows its own, but with a fresher date.
After that, the sd card is not detected. Android does not see it and does not determine its memory. And other sd too. Without a card, the phone sees its memory and works fine. What to do if the phone does not see the sd card after the actions of the virus?
2. I put an sd card in the computer - everything reads well there, you can see. And in the phone there is an inscription: SAFELY REMOVING THE CARD. Why does the phone not see the memory card? What to do?
Answer. If the phone does not see the memory card, this may be due to damage to the file table on it. How this is connected with the recovery, it is not clear. Try formatting the sd card. If nothing changes for the better - change the firmware.
1. I bought a 4G micro flash drive in my phone, installed it in a computer via a card reader, wrote files and installed it in my phone (Microsoft Lumia 530). After a while, I installed it again in the card reader and connected it to the computer. Windows gave a message that the device is faulty and does not read the USB flash drive, but everything works fine through the phone. And this happens with all usb media and devices. I checked flash on many computers before installing it on the phone - everything is OK. After installation, the memory card does not work on the computer - only through the phone.
2. I ordered a flash drive forebay(flash drive universali- flash device). Yesterday I received it, inserted it into the phone - it works, it also works on the computer. Today I tried to transfer a video from my phone to a USB flash drive, copying began, I left the phone and went away. Upon returning, I found that the program was closed, and the flash drive was no longer detected on the phone, nor was its computer detected. What to do?
3. I bought a 32 GB flash drive in my phone from Aliexpress. It worked fine, then the photos that were saved to it were cut off halfway or instead of them there was a gray screen. In the end, it stopped being detected by the phone. The computer seems to detect it, but does not tear it off. Writes something like "insert disk". I tried a lot of things that were written on the Internet, a lot of programs. Some do not see the flash drive, some see it, but still cannot format it.Tell me how to make her feel.
Answer. Format the flash drive via phone or Recovery (we wrote about this at the beginning of the publication. If it doesn’t help, go to Windows Disk Management and check if the flash drive is mounted when connected to a PC, if the volume is displayed in the list. If necessary, you can create a new partition on the flash drive and format in FAT or extFAT using specialized programs.
I turn on the music on the phone, he writes: there are no music files. Phone nokia RM-1035 and mirex micro sd (HC) class 4, everything worked yesterday. Probably, the memory card is not readable! How do you know if it's working or not?
Answer. Check if other mobile applications see the contents of the memory card, for this you can install another player. Connect the microsd card to a computer or laptop through a card reader. If the flash drive is not available in both cases, try the other methods described in the article.
The Samsung Galaxy A3 2015 phone does not read the flash drive. I formatted it in all possible formats, but it did not help. Connected to a PC - everything works fine. Why does the phone not see the flash drive? Maybe something in the settings of the phone needs to be changed?
Answer. Go to Settings - Memory. Check the "SD memory card" section. Install a file manager and see if the files on the memory card are displayed on it.
In addition to standard formatting, you can try low-level formatting - however, not all manufacturers offer their own software for this (check the memory card website).
Another reason why the phone does not see the sd card may be the lack of contact between the memory card and the phone. Check if your device reads other flash drives. If not, take your phone in for repair.
Doogee x5 phone. The phone did not see the memory card, but it was there. Accidentally transferred data to external memory. For some reason, the transfer was made, but the map was still invisible. Pictures, videos, music, safely disappeared somewhere. How to get them back and why the phone does not see the memory card? Is it possible to restore all this somehow? Tried Android Recovery - to no avail.
Answer. If the phone does not see the sd card, then how did you transfer the files to it? Perhaps you just copied them to another place.
Try to connect the memory card through the card reader to the computer and scan it with the CardRecovery program. As for Android Data Recovery, this program is less functional.
After disabling the sd card to work in aparted and performing manipulations in it, the prestigio phone does not turn on the sd card again. By the way, the laptop does not see the memory card either. Actions in recovery did not help. What to do if the phone does not see the memory card?
Answer. Perhaps the operating system and the laptop see the sd card, but the markup has fallen off. You need to create a volume on unallocated space. Start - Run - diskmgmt.msc. Find the unallocated area and use the context menu to create a new volume on the sd card, assign a letter, apply formatting. The sd card disk after these manipulations should be determined as before.
I connected the camera as in the instructions (via the USB port), but the camera reads as a Portable Device, but it needs a Removable Disk. The camera does not see the memory card in connection mode or what is the problem? How can I change the display? Camera Nikon Coolpix S9400.
Answer. Your camera supports SD, SDHC and SDXC memory cards. The computer does not see the memory card as a drive. You need to remove the card from the camera and connect it to the PC via a card reader. If you have a card reader built into your laptop, it will be even easier to connect the card. After that, you will see the removable disk in the list.
mico sd 32G in android tablet. I will twist in the connector - everything is ok, but after a while the conductor does not see it and through the settings menu, the SD card memory does not turn on. if you pulled out and inserted a memory card, it appears. I cleaned the contacts, wiped them with a rectifier, but still Android does not see the sd card where the dog is buried?
Answer. Try testing another sd card with your phone. If the situation repeats itself and the smartphone does not see the flash drive (the memory card disappears from time to time) - most likely, the matter is in the contacts of the phone.
If another memory card works without errors, we advise you to format the problematic card in FAT32 or exFAT - in case the phone does not see the micro SD flash drive due to errors in the file table.
The phone (Samsung Galaxy S5) does not read the memory card. I inserted three cards, and does not read any of them, although they are correctly displayed on other devices. At the same time, the inscription "Connect SD-card", the font of which was previously gray, becomes white and available for pressing, but if you press it, nothing happens. All photos and pictures in the gallery (located in the phone's memory) are not displayed. And applications that are not in the internal memory, but in the phone's memory, do not open. Tell me what to do?
Answer. There may be a failure at the level of the Android operating system or installed applications. Try to manually resolve the conflict by deleting any unnecessary apps from your phone. Update the OS version to the latest through Android settings.
If the phone still does not see the memory card, check the phone contacts: are there any visually noticeable damage on them?
Do you write "on other devices" while referring to the computer? If yes, it is likely that the file system of the flash drive is NTFS, but you need to format it in FAT or exFat.
When I insert an sd card into the phone, the device does not detect it. Whatever I tried: even inserted into other phones, still does not see and does not read its contents.
Answer. There is too little information about the memory card (it is practically non-existent) to give specific advice. First, check if your phone supports sd cards of the size that is on your card (see the documentation for your smartphone or tablet). If you have just bought a memory card, you can exchange it under warranty for another one - a smaller one.
If you have previously used this memory card and it is no longer detected on this and other mobile devices, it is most likely out of order.
1. I cleaned the sit card on the computer. Deleted everything from her. Now the new smartphone teXet X-plus TM-5577. I inserted a sit card, he sees it, but nothing is downloading on the sit card and I can’t transfer anything to it. Tell me what to do?
2. The phone started to turn on by itself periodically (Lenovo A 526). Then I went out of the house and plugged in the headphones and noticed that not a single track was playing. Later, when I took out the phone, I found that the flash drive was not readable and the saved music was not playing. I tried to reboot the phone - it does not help, I put it in the card reader - it sees a memory card, I put it in my friend's phone - too. And I don't want to. And the most important thing that knocks me out of my thoughts is a notification after turning on the phone with the phrase "Dismantle the MicroSD before deleting so as not to lose data.
Answer. You need to reconnect the memory card to the computer (as you did before), format the sd card in the standard way (for example, through Explorer) or using sdformatter. The file system is FAT32. Most likely, it is due to incorrect formatting that the phone cannot write data to the memory card.
After a sudden shutdown, the tablet (android 5.1) stopped recognizing the memory cards in the card reader normally. Writes either error checking is in progress, or reading is in progress, which lasts indefinitely. At the same time, half of the programs stop responding, everything slows down wildly, and it becomes impossible to turn off the tablet (only when it is discharged to 0 and cut down). Sometimes (very rarely) after connecting, he sees it, but at the slightest manipulation with the card (even viewing a photo), he immediately loses it and starts re-reading it again, and already with the ends. Tested on 3 flash drives, both clean and not, with different formatting and a bunch of dances with tambourines (all according to recommendations on the forums). The system was reset. Nothing helped. He refuses to see a card for 8 gigs at all, although if you connect it through an adapter to a usb connector, everything works fine (like other flash drives). What is the problem, in the card reader or in the system?
Answer. It is best to connect the problematic memory card to a laptop or, alternatively, through a usb adapter, as you mentioned. Next, the sd card needs to be formatted.
Most likely it's the card reader. Many cheap card readers stop reading memory cards correctly after a short time and give copy errors or read information slowly.
The system (Android) is unlikely to be related to the problem, since you have already tested several memory cards. Perhaps it's a specific application that slows down the system, but this can only be calculated by resetting the phone to factory settings.
Phone Lenovo vibe shot, android 6. costs sony sd card 32gb in the option as an extension of the main memory (ext4). The phone stopped seeing the file system - writes SdCard0 01/01/1970, 00 kb. Windows 7 sees two sections - 16Mb and 30Gb, serviceable, free 100% each.
How can I return everything to its place with the restoration of the old files? well, or at least how to pull out photos and a folder of vatsap?
Answer. R.saver or AOMEI Partition Assistant Standard Edition are suitable for recovering a deleted partition on an sd card. If the file table on the partition contains errors, you can try to fix them using the chkdsk utility under Windows. If it doesn't help, try scanning the sd card (unreadable partitions) with the Recuva utility. Until you overwrite the information on the flash drive or format it, the chances of getting the files back remain high.
Samsung A3 2017 Samsung memory card 64 gb. Created folders from the computer: photos, ringnotes, music, videos, movies, etc. The phone sees only audio, pictures, documents, videos. Other folders do not see on the memory card. What needs to be done?
Answer. Install any file manager for your phone (for example, Total Commander or ES Explorer). Create folders directly through these programs and copy everything you need there. The files should be readable on the memory card without problems. It is also possible that those folders that are not readable from the sd card are hidden or corrupted. So it will not be superfluous to format the card in order to avoid further errors.
Lenovo A2010 phone does not see sd memory card. tried to reboot, writes "Only one sd card is available, it is impossible to perform switching." Other phones do not have a card. In the computer through the card reader does not show at all. Is this really the end, so many photos and videos are gone? Maybe something can be done?
Answer. It looks like there are reading errors on the card or the markup has fallen off. Since the memory card does not open on the computer (i.e., the letter / separate drive is not displayed in the file manager), it makes sense to check if the memory card is recognized as a device at all. To do this, go to diskmgmt.msc (Start - Run) and see if unallocated space appears when you connect the sd card to the PC. If it appears, create a new file volume in this space via the context menu. If nothing happens, most likely the sd card is out of order.
Phone model sony xperia m4 aqua dual. Within two years, a microSD memory card was installed in the phone. Recently, failures began to occur: at first, in order for the memory card to work, it was enough to restart the phone. Now the phone does not see the map at all. Formatting failed. Installed a new one. The phone recognizes it (it is in the settings, the photos were sent to the card), but the applications cannot be downloaded from the play store (it still shows the download option only to the phone's memory). What needs to be done in this situation with a flash drive?
Answer. Format the memory card with specialized applications - the same SDFortatter is fine. Next, check the card for errors using the chkdsk tool.
However, you clarified that changing the memory card does not help. The problem may be caused by specific applications or software conflicts within the Android OS. In this case, we advise you to update the firmware or, as an extreme option, reset the phone (perform a hard reset).

Answer. To check the sd card, use the following options:
chkdsk (drive letter): /f/r
- /f - fix file system read errors
- /r - fix bad sectors on sd card
This should fix the errors and allow you to format the sd card in the standard way or through utilities like SDFormatter.
there is a Kingston DTSE3 16G usb drive, the computer does not see it, the flash drive is not readable. Periodically, the system displays a message stating that the device can work faster or. Are there any recovery programs?
Answer. The flash drive supports the USB 2.0 interface. Your computer (motherboard) may have an older version of the ports, due to which a similar message appears. Therefore, we advise you to update the hardware of your PC if you have not done this for a long time.
Recovery programs will not help you, but the correct formatting of the flash drive (in NTFS / FAT) and subsequent error checking through chkdsk will not interfere.

Answer. If there are important files on the memory card, make a copy of them on your computer. After that, format the memory card and check it for errors. If everything is in order, you can use the sd card on your tablet or phone, write files to it. If the situation repeats, update the tablet firmware or perform a hard reset. However, this is already an extreme measure, we advise you to deal with reading errors first.
