Starting with androil 6.0, it became possible to use a flash card as internal storage device data. Now the device, after certain actions, can use the memory available on SD as freely as the internal one. The article will talk about how to connect an SD card in this capacity and what restrictions are imposed on it.

How to connect a flash drive as internal memory

Before connecting the drive, you must transfer from it all important information. During the setup process, it will be completely cleared and you will not be able to return the data.

First of all, you need to go to Settings and then go to the " Storage and drive”, where you should click on the SD card.

Next, choose " Tune» and click « Inner memory". Immediately after that, the device will warn the user that all information will be deleted and it will become unreadable on other devices without full formatting.

Here you need to select the item " Clean and Format” and wait for the memory cleaning process to complete. You may then see a message that the media is running slowly. As a rule, this means that the flash drive used is not of very good quality and its use as device storage may also affect the performance of the smartphone itself. For good and fast work recommended to use UHS Speed ​​Class 3 (U3) drives.

After formatting is completed, the smartphone will require you to transfer the information, you should agree with this and wait for the work to complete. After the transfer, the work of turning the flash drive into internal memory will be almost completed, it remains only to reboot the device.

Features and limitations of using an SD card

There are a few things to be aware of before using a flash drive in this way.

1. After conversion, all data, except for some applications and system updates, will be placed on the SD drive.
2. When connected to a computer, only this part of the memory will also be available for interaction.

In fact, all actions are performed only with a flash drive, the real internal storage of the phone not available for interaction and, practically, is not used in any way. Firstly, this means that when you remove the drive, almost all data, photos and applications will be lost. Secondly, if the volume of the flash drive is less than the actual storage capacity of the smartphone, then the amount of available memory will decrease, not increase.

Format the card with ADB for use as internal storage

On some devices, the function is not available, but it is possible to connect a USB flash drive as storage in another way. However, it should be noted that this method is very laborious and can harm the device, therefore, if you are not confident in your abilities, then it is better not to do this on your own.

To use this method, you will need to perform a lot of actions. You need to download from the site and install Android SDK, then download and install from the official website device drivers, and you also need to enable " debug mode byUSB» on the device.

• adb shell
• sm list-disks (after execution, the id will be given in the form disk:XXX,XX it should be written down and entered in the next line)
• sm partition disk:XXX,XX private

Then it will take turn off the phone, go to settings and click on sd, select menu and click " Transfer data". Everything, on this action is completed.

How to put a memory card in standard mode

To return the flash drive to standard mode, you just need to go to its settings, as in the first option, and select " Portable media". Before that, all important information should be transferred to another location, because the drive will be formatted in the process.

Of course, many people know about memory cards. Someone will even be surprised - why do we need an article about them. However, not all so simple. There are many people among my acquaintances who do not really know anything about memory cards. And at the same time, they do not live in a hut in the forest, eating fir cones. They quite actively use the Internet, mobile phones, sometimes even communicators and tablets. Therefore, I consider it necessary to first talk about what memory cards are. And then I will move on to considering their varieties, classes, brands.

What is it - a memory card?

A memory card is such a small and rather plump plate that has a built-in flash memory module. This module is non-volatile, that is, the information on the memory card is stored even when it is removed from any device. Information on the memory card can be deleted, overwritten, and so on. The service life of a memory card is very long - tens of years. The information on some cards can be protected in certain ways.

Varieties of memory cards

There is a whole bunch various kinds memory cards. I will only cover the most common ones.

SD (Secure Digital). Perhaps the most popular type. It is used in many cameras, camcorders, tablets, old players, communicators and pocket computers. Differs in the low price. It is sold in almost all communication stores, computer stores, in many markets, in kiosks ... The maximum volume is 4GB.

SDHC. All SD memory cards larger than 4GB (and many 4GB) are called SDHC (their maximum capacity is 32GB). This format is characterized by a higher speed of operation (data exchange, data recording) than SD. It is preferable, of course, to purchase SDHC cards, but keep in mind that some older devices may not work with them.

SDXC. A new standard that has not yet been widely adopted. SDXC cards are distinguished by a very large capacity - up to 2 terabytes (and this is 2048GB!) And a very high data recording speed. They are expensive and don't come up for sale very often. Moreover, this format is still supported by very few devices.

MiniSD. Similar to SD, but noticeably smaller. Nowadays, it is practically not used anymore, miniSD has been replaced by the microSD format. It is problematic to buy miniSD now, but they are expensive due to their rarity.

Micro SD (TransFlash). It probably currently ranks second in popularity after SD / SDHC, but in the near future it has every chance of becoming the most popular memory card format. Differs from SD in very small sizes; microSD cards are even smaller than miniSD. This is both a plus and a minus: on the one hand, with the advent of microSD, it became possible to reduce the size of devices; on the other hand, such a miniature card is easy to lose. Prices for microSD cards are almost identical to those for SD cards.

microSDHC. Cards microSD memory larger than 4GB (and many 4GB) are called microSDHC (their maximum capacity is 32GB). This format is characterized by a higher speed of work (data exchange) than microSD. It is preferable, of course, to purchase microSDHC cards, but keep in mind that some older devices may not work with them.

memory stick. Memory card format developed by Sony; is closed. The speed of work (writing / reading data) is high; the maximum volume is 16GB. Exist like big cards Memory Stick, and small - Memory Stick micro (M1, M2). The Memory Stick is distinguished by a high price (in my opinion - clearly overpriced). Used in Sony, Sony Ericsson devices. It is often found on sale, almost everywhere.

compact flash. An obsolete format that was previously widely used in PDAs. CompactFlash cards are very different large sizes- in comparison with SD. Now used by only a few users. The main advantages are the very high speed of data recording. The maximum volume is 256GB.

smart media. This is a deprecated format. Buying SmartMedia cards is almost impossible, and their maximum capacity is only 128 MB.

MMC. Also an outdated format, earlier former competitor SD. Differs from SD in a slightly smaller thickness and greater efficiency. MMC cards can be inserted into the SD slots of devices (but an SD card cannot be inserted into the MMC slot!). MMC cards are now rarely seen on sale.

xD. Format developed by Olympus and Fujifilm; is now slowly falling into disuse. xD cards are notable for their very high prices; only Olympus and Fujifilm devices work with them. Compared to SD cards, xD is perhaps only worse - for example, the maximum capacity of xD is only 2GB.

Memory card slots

If the device allows the use of memory cards, then it is said that it has a slot for memory cards. A slot is a hole (slot) where a memory card is inserted. (Of course, this is not a simple click, but a special click: special contacts are connected to it, with the help of which information is read from the cards). One device may have memory card slots different types, but usually there is only one slot. And in most modern devices - for microSD.

Memory card adapters

As you learned from the material above, memory cards can be divided into two types (according to size): large and small. The most popular large cards are SD and Memory Stick. The most popular small ones are microSD and Memory Stick Micro. You can replace that the technology of SD and microSD, in general, is the same, the difference is only in size and some details. That is why it is possible to use so-called adapters (some call them "shirts").

An adapter is a device that looks like a big memory card, but in reality is a kind of miniature box. You can insert a small memory card (for example, microSD) into it, and after that the adapter itself will turn into a full-sized memory card (for example, SD). The small card in the adapter can be used with a device that only supports large cards. Classic example- put microSD card from your phone to a camera that supports SD cards.

All this provides versatility, the ability to quickly and conveniently transfer data from one device to another without the help of a computer. That is why it is better to buy a microSD card - you can always use it with a device that supports SD cards. But the opposite is impossible: the size of the SD card cannot be reduced in any way!

It is worth noting that adapters are usually sold with small cards. But even if the adapter is not included, you can buy it additionally - the issue price is usually no more than 100 rubles. It is not necessary to buy an adapter from the same company that produced a small memory card: there is no difference between adapters of the same format from different manufacturers.

SDHC/microSDHC Memory Card Classes

On packages (and often on the cards themselves) with SDHC / microSDHC cards, you can read information about the so-called card class. It is denoted by a number (number). The higher the number, the higher the speed of the card (the speed of writing and reading data). Usually, the higher the power consumption of the card and, of course, its price. Here is a list of these classes:

• class 2 - data recording speed not less than 2 Mb/s
• class 4 - data recording speed not less than 4Mb/s
• class 6 - data recording speed not less than 6Mb/s
• class 10 - data recording speed not less than 10Mb/s
• class 16 - data recording speed not less than 16Mb/s

Available for sale and SDHC cards"without class" - the speed of writing data to them usually does not exceed 1 Mb / s. Also, cards with an even higher write speed (higher class) appeared on sale, but I see no reason to buy them - the price is high, and the benefit is doubtful.

For cameras and camcorders, it is advisable to buy memory cards of a class no lower than class 4 (although, in principle, class 2, and even “classless” cards, are enough for amateur photography). To record video in high resolution, a class 6-10 or higher card is desirable. For readers and phones, the most common "no class" cards will be enough.

Memory card capacity

Many people have a question - what capacity memory card should I buy? The answer, in general, is simple - you need to proceed from your own needs. I hope that the following list will help to determine them, which shows how much memory is occupied by files of different types:

• Documents DOC, XLS - usually within 1Mb
• Electronic book (FB2, EPUB, TXT, MOBI) - usually within 1Mb
• Photo 8-10Mpix of excellent quality - usually within 3Mb
• Good quality 5MP photo - within 1Mb
• Song 3 minutes in average quality - about 3Mb
• Song 3 minutes good quality- about 6MB
• Film in more or less decent quality - about 500MB or more
• Movie in good quality - usually 1GB or more

I also give one more list, which indicates what size cards it makes sense to buy based on the device for which you purchase them:

• For a reader (reader) - 4GB is enough
• For a phone - 4GB is enough
• For a communicator (smartphone) - better 8GB, or even 16GB
• For a tablet - 16GB is better, if you like to watch movies - 32GB
• For the camera - 4GB (if you shoot only photos and not very many), 8-16GB (if you shoot a lot of photos and occasionally - video)
• For a camcorder or camera that shoots video in good quality - 16GB, and preferably 32GB

Card Readers

Memory cards are mainly designed for use in portable devices - digital cameras, players, phones, tablets. But if desired, they can be connected to both laptops and desktop computers. This requires a small device called a cardreader. Some (usually quite expensive) laptops and desktops already have a card reader built in; for others, you need to buy a separate device, its cost is from 150 to 700 rubles (in very rare cases, higher).

The card reader is connected to the USB port of a computer/laptop. First you need to insert the card into the card reader, then connect it to the computer. A removable drive will be displayed in Explorer - this is the memory card; You can work with this removable disk as with a regular flash drive. At the end of the work, the card reader must be removed from the USB port (after having "safely disconnected" the device), and then the memory card should be removed from the card reader. Such a simple mechanic.

Perhaps more popular are card readers designed to work with only one type of memory card - for example, SD. They are low cost and compact in size. Card readers for microSD cards, by the way, are very small, and they can be used like ordinary flash drives - just insert a microSD card into the card reader. Of course, SD, xD and so on card readers can be used as a flash drive, but their size is noticeably larger.

Now the so-called universal card readers are also common. With them, you can use memory cards of almost all formats: SD, microSD, Memory Stick, Memory Stick micro and so on. They are, of course, larger than conventional "mono" card readers, and are somewhat more expensive. But personally, I recommend purchasing just a universal card reader - after all, you can use any cards with it.

Some features of memory cards

Perhaps, memory cards have only one drawback: they are quite voracious. This means that a device that does not have a memory card inserted will last longer without recharging than a device with a memory card in use. However, the difference in operating time is usually small, and I would not call this minus significant.

Another feature of memory cards is open (in the vast majority of cases) contacts. Accordingly, you need to be quite careful, try not to damage these contacts (do not scratch, for example), to prevent accumulation of dust and dirt on them.

Another feature of memory cards is that some models of the same type may not be compatible with specific electronic devices. In practice, this means that the SD card may simply refuse to work with your reader, phone or tablet: the point here, as a rule, is some minor flaws in the device software. This feature must be kept in mind, and when buying a memory card for a device, it is necessary to check its compatibility with this device. Otherwise, you may be disappointed.

Manufacturers and brands of memory cards

A lot of electronics manufacturers produce memory cards. Perhaps the most famous are SanDisk and Transcend. They issue cards of various formats and classes; prices for SanDisk and Transcend products are quite high. At the same time, SanDisk (and Transcend) cards, for example, do not work with some devices - it is not known who should be blamed here, but the fact remains, and you should not think that a high price automatically guarantees absolute compatibility. But in general, the cards from SanDisk and Transcend are very high quality.

Kingston and Apacer memory cards differ in lower price. Their compatibility is also not absolute, but I can say that Kingston cards (according to my subjective feelings) are compatible with a large number devices than SanDisk. In general, Kingston is a kind of golden mean, excellent value for money. Apacer cards are usually a little worse in quality, and their compatibility level is lower, but their price is even more modest.

Of course, memory cards are also produced by other manufacturers: Toshiba, Samsung, Silicon Power, A-Data, and so on. The list is very long, I see no reason to list it in its entirety. In any case, all the manufacturers mentioned above produce high-quality products that you can buy without fear (but - preferably - with a test on a specific device).

Do you want to use the MicroSD card as a real storage expansion and install apps on it? To do this, you need to format it as internal memory. This is fairly easy to do on most phones, but unfortunately some manufacturers like Sony, LG or Samsung don't have this feature by default. But if your smartphone is equipped with Android Marshmallow or newer, then you can use the command line. True after that, avoid Android updates. How to combine memory correctly, we will tell in this article.

The easy way

If you're lucky, your smartphone will allow you to do this without connecting it to a PC. This method will most likely be your only hope if you are using more new version Android (7.0 Nougat or 8.0 Oreo). Here's how to check:

• Install SD card in Android phone and wait for it to be recognized
• Open Settings > Storage
• Touch the name of your SD card.
• Touch the three vertical dots in the upper right corner of the screen.
• Click "Settings" .
• Select Format as internal memory.
• Click "Clean and Format"
• Android will then prompt to transfer the data

If your smartphone does not allow you to do this, the process becomes more difficult. We will move on to it below.

What to do if your phone won't let you format microSD as internal storage

Some smartphone manufacturers disable the common Android feature to format a microSD as internal storage, hiding the ability to do so from your phone. But it is still possible to activate this process using a PC without requiring any root privileges.

The exact steps vary depending on android versions your phone. This method worked well with Android 6.0 Marshmallow and Android 8.0 Oreo, however we ran into trouble on Android Nougat.

For phones using Android 6.0 Marshmallow

When the MicroSD card is formatted as internal memory, applications can be fully stored on it. This means that if you download the application overall size 2 GB, then the SD card should have 2 GB of space. If, however, the MicroSD card is formatted only as a backup, there will not be enough memory, as it says PLATYPUS_DIARRHEA on reddit.

Just because a menu option is invisible doesn't mean it doesn't work. A few days after posting on Reddit, it was revealed that it was also possible to format the MicroSD card as internal storage in the Galaxy S7 using the command line. We have successfully tested the instructions with Samsung Galaxy S7, Sony Xperia Z5 and LG G4 running under Android control 6.0 Marshmallow.

All three smartphones work from the factory or have been updated with Android 6.0 Marshmallow and have a microSD card slot. Also, there is no menu option to format the microSD card as internal storage. The feature is only available on HTC One A9 and Motorola on all Moto smartphones.

Why did Samsung, LG and Sony hide this item? I connected each of the three smartphones to the computer, and each of them had one microSD card.

I then entered in the commands described in my blog. Once you open a command prompt window and connect your smartphone, you can enter the first command:

• adb shell

Now the command line is ready to run system commands on your smartphone. In this case, we want to format the SD card or part of it as internal storage. Even if Sony, Samsung and LG deny us this option in the graphical user interface, we can still execute this command through the console. First, however, we need the ID of the SD card. You can find it out with the following command:

• sm list disks

In my case the disk is called 179.64 . Perhaps yours is different. Note the exact ID. In the following command, we will format and partition the MicroSD card. Your content will be removed. If there are important files on the card, copy them to another drive or computer. If you want to keep a MicroSD card in your smartphone all the time, you can now partition all your memory. To do this, enter:

• sm partition disk:179,64 private

The operation takes a few seconds or minutes, depending on the capacity of the memory card. If you want to use only a certain percentage so that other devices can read it, you must exclude it from the personal section. The 50:50 split command looks like this:

• sm partition disk:179.64 mixed 50

This is the end of Paul O'Brien's guide, but not the end of the job. If you now want to use the reallocated memory, you must migrate applications and data as well. This can be done through the "Storage" section in the menu android settings. Select the MicroSD card, then go to the top right side of the menu and click "Move Data". You cannot select this menu item before splitting.

Now all downloaded applications will be completely written to the MicroSD card. Only system applications and updates use internal memory. This means that you will never get an error due to lack of space.

Smartphones with Android Oreo

Recent Android updates have changed the rules a bit, but it's still possible to use this method with ADB. Just start working with ADB by the method above, but after entering shell adb you will be prompted to set certain values.

Enter the following lines to unlock the ability to format microSD cards as internal storage on your phone:

G8141:/ $ sm set-force-adoptable true
G8141:/ $ sm list-disks
disk:179.0
G8141:/ $ sm partition disk:179.0 private
G8141:/ $ sm set-force-adoptable false
G8141:/ $ exit

We tested this method on a Sony Xperia XZ Premium running Android 8.0 Oreo and it worked. In the screenshots below, you can see a 16 GB microSD card installed as internal storage:

Problems with system updates and Nougat

Some readers have reported difficulties installing system updates in Android 6.0 after using the above methods. Upgrading to Android 7.0 Nougat is not possible after installing MicroSD as internal storage. Our test devices with Android 7.0 Nougat don't even respond to the console commands shown above.

Due to the lack of documentation on the web, we can only recommend that you perform a number of operations before updating the system. Back up your photos or music to your computer or the cloud and free up as much space on your SD card and smartphone as you can.

Delete unnecessary applications and return the data to internal memory. Then format the MicroSD card as removable media. Only then can you safely install the Android update.

What's the catch?

MicroSD cards do not work as fast as the built-in memory of a smartphone. So don't waste your money on cheaper ones, and instead buy yourself memory cards with reasonable read bandwidth. Extreme Pro and MicroSD from Sandisk were, in our opinion, the best in terms of price / quality ratio. With a write throughput of 74 MB/s, you shouldn't experience lag. Such cards are best suited for installation as internal memory.

Interestingly, only the LG G4 was able to read the extended memory correctly. Samsung showed unnatural a large number of occupied memory, and Sony's memory was even negative. However, we didn't have any complications, and even when we were connected to a computer, we were able to access all of our data properly, although we could only see the general and not the specific part of the memory. Difficulties arose only in the case of a system update (see above).

Memory Boost: Complete Success

We subjected all the smartphones described above to a single endurance test. We have installed Final Fantasy IX on all devices. The game size is 1.8 GB. After installation, it is easy to see which of the two types of memory, internal or SD card, was used. In all cases, after installation on an SD card, 1.8 GB less space. This degree of success cannot be achieved with SD cards formatted as external memory, as full data migration is not possible.

Compare the values ​​of internal memory and SD card memory in the screenshot to confirm.

What happens if you remove the microSD card?

Of course, the question is what happens if the MicroSD card disappears from the system. In fact, this creates a serious problem for your applications. Eventually, they can no longer access their data. Since your operating system partitions and factory reset information are still stored in the internal memory, a removed or broken SD card cannot do much harm. When we removed the microSD card, the app icons simply disappeared, and when we reinstalled them, they returned back.

If you lose or break your SD card, your data will be lost. Since they are encrypted as internal memory, you may not hope for data recovery. Instead, use regular backup. So feel free to enjoy the cheap memory expansion of your Marshmallow smartphone.

Safe removal of an internal broken SD card

To safely remove the SD card from your smartphone, you must reverse the process above. Since your internal storage space is probably not enough, you first need to transfer your photos and other data to another storage, such as HDD your PC.

Then go back to settings "Storage and USB drives" and press "Move data to internal memory" on the menu. Then format the SD card like external memory. Perform both steps (backup and format) so that your data cannot be lost and you can use the SD card with other devices.

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. Fast way fix the problem - restart the phone in recovery mode and in service android menu select the Wipe cache partition option. 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. Most bad moment- all data that was stored on the memory card of an Android or iOS phone disappears permanently. 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 formats file systems.

1. Last chance to find the answer to my problem. Samsung phone galaxy not 5 (china) uses only its internal memory, and the flash drive is not detected. What I just didn’t do ... And I ticked, and in another mobile phone inserted, formatted and this way and that - does not 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 manipulation 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 in better side- 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.
