The camera does not turn on or runs out of power quickly

When the camera does not turn on, there can be two reasons: a complete discharge of the battery or the camera itself has broken. The second option will require contacting specialists.

If the charger has not been used for a long time, the indication of the charging process does not appear immediately.

Other reasons why the camera does not turn on:

  • Battery wear, average service life. 2 years;
  • Excessively powerful charging that charges quickly, but not fully;
  • Defective battery.

Why does my camera run out of batteries quickly? Most likely, their capacity is too small. Any instruction indicates the recommended mAh amount.

Your camcorder and camera can run out of battery quickly if:

  • Autofocus is constantly used;
  • Too often the use of automatic ZOOM-zoom, give preference to manual adjustment to save battery;
  • When using the camera, the flash is constantly turned on;
  • Using the LCD screen with a viewfinder, on sunny days it is better to use the optical viewfinder.

IMPORTANT! If the camera cannot see the battery, check the charging connector.

The device does not see the memory card

The camera does not see the memory card or does not allow working with it in principle. This can happen in three cases:

  • new memory card;
  • the media was used in another device;
  • the card is faulty.

If the device does not see the memory card, then it is highly likely that it was formatted for a different technique or has just been purchased. Any technique formats the card for itself. Most often this happens when the media is connected for the first time: the device realizes that the memory card is new and offers to format it. In this case, the user just needs to accept the offer and the technician will do everything.

If the camera, in principle, does not see a new memory card or previously used in another technique, then it can be formatted via a PC. It is quite simple to do this:

If the memory card in another device works, then it is not compatible with the camera. You should refer to the instructions and find the desired option. It is worth remembering that each camera supports memory cards up to a certain size and with a certain speed class. Currently, the minimum class of memory card for a camera is tenth. The volume can be up to 64 GB or more.

PC connection problems

If, when connected to a computer, it displays a memory card error, then this does not mean at all that the problem is in it. There is a possibility that the port itself is faulty. Try plugging in the drive through the front connector, then the back one. Connect the camera memory card using a different cable.

When the computer does not see the camera, it is possible that the reason is in blocking programs, which regard the new connection as a potential threat.

If Nikon does not see the map, you need to take the following steps:

  • In the “Start” tab, select “Control Panel”. “Security System”;
  • Go to Windows Firewall and turn it off, then turn it on;
  • To save the changes, click the “OK” button.

After restarting, the computer should not give an error.

An anti-virus program can act in a similar way, to check this, you need to turn it off and try to reconnect the camera.

The memory card is blocked for recording, the camera works with the flash drive normally, but the computer does not see it. Check the card with an antivirus. He writes anyway. the card is protected, go to the registry. In the branch: HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Control StorageDevicePolicies. Correct the value of the WriteProtect key to “0”.

Doesn’t see a USB flash drive from a PC camera. If one of the disks on the computer and the drive have the same name. For example, “E”, then the PC will never display the map until you rename it.

Writes a memory card that it is not defined. Wipe the drive contacts with a dry cloth. If the message persists, format it.

The computer does not see the USB flash drive in the camera

There are two ways to view photos on a computer:

  • connect the camera through the cord;
  • insert the memory card through the card reader.

Sometimes, when connecting with a cord, a situation arises that the PC does not see the memory card or refuses to copy data from it. Common Problems. Uninstalled Drivers or Protection on the Camera.

If the computer does not see the memory card or prohibits copying from it, then there may be a lock in the camera, which does not allow you to do something on the memory card from other devices. In this case, you need to look at the camera settings: sometimes the function can be disabled. If not, then the memory card will have to be removed. If the memory card is not visible at all, then it is possible that the wrong mode was selected when the device was connected. Some models can only transfer data when connected to a laptop, while others can also be charged via a USB cable. To fix the problem, you need to reconnect the camera and look at the display. there may be a suggested connection type. If such a window does not appear, then you should look for the desired option in the camera settings.

It should be emphasized that it is easier to insert a memory card directly into a computer, since in this case the camera settings do not affect the storage medium in any way.

PC connection problems

Memory card problems

All faults can be conventionally divided into 5 groups:

  • Brain teaser. The camera writes. “the disk is not formatted” or writes: “the card is protected”, the information is displayed in the form of RAW. Failures of the file system can be eliminated with the help of special equipment. If the card is blocked or information is accidentally deleted, formatted, then this can be corrected by yourself.
  • Mechanical. The drive can get wet, crack, break. What to do if water gets into the drive? Never insert it into the camera until it is completely dry.
  • Thermal and electrical. Power surges, simplification of electrical circuits to make the final product cheaper, and poor build quality are possible reasons why the camera does not see the drive. It is believed that the drive can withstand overheating up to 125 degrees, in practice, problems arise already at 70.

A memory card error in most cases occurs against a background of several reasons.

The camera writes “memory card is locked

Almost all types of drives have a forced blocking function. In this case, the drive is visible, you can view its contents, but nothing else can be done. What to do if it happened?

It is necessary to remove the card from the camera. On the left side there should be a small switch, above which there is an inscription “lock”. The lower position indicates that the drive is locked, that is, the switch must be moved up.

If the MicroCD memory card is blocked, then the toggle switch must be found on the adapter.

Memory card error: what to do? The problem may arise if the card is new or has been used with a different technique. The easiest way is to format the drive, as suggested by the Nikon camera itself.

Formatting can be done on a computer using the following algorithm:

  • Place the drive in the laptop;
  • Find storage media;
  • Select “format” on the drive, right-click;
  • Choose a suitable system: “fat32” or “ntfs”;
  • Carry out formatting.

The procedure did not help, and the camera still writes. there is a memory card error or it is locked, most likely that it is completely incompatible with the device. Compliance is checked with another apparatus.

The device does not see the memory card

Why can’t the camera see the memory card? It’s no secret that the drive case is not durable. Any scuff and crack can provoke a refusal to work. It is possible to recover data in 99%, except if the memory chip is damaged. They can fix the problem in the workshop by replacing the case.

Why can’t the camera see the memory card? The second common problem is controller failure.

It manifests itself in the following errors:

  • The size of the map is specified in 0 KB;
  • Error code 43 or 10;
  • The message “insert the disc into the device” appears on the camera.

If the card cannot be removed, then you should not do it yourself, it is better to contact a service workshop.

Why won’t the camera read the memory card? Possibly degradation of memory cells has occurred, which has a limited read and write cycle. In this case, it will not work to repair the card, but you can extract information using special utilities.

IMPORTANT! If the drive is inserted correctly, but the memory card is not visible on the camera, but it is detected on other devices, then most likely the problem is in the camera.

Memory card error: what to do? You can purchase a special device. unlocker.

It’s very easy to use:

  • The device connects to the PC;
  • The card is placed in the unlocker;
  • Unlocking is carried out, at the end of the process, the LED will light up.

How to unlock the memory card yet? There are many special utilities, for example, PC Inspector Smart Recovery, with an intuitive interface.

Is the memory card in a Canon camera read only occasionally? The problem is in the card, it has a low “class”, and the camera itself takes pictures in a very high quality.

This information is printed on the card itself, it is better to choose class 6 and higher. If the camera says that the drive is locked, then check its speed class and replace if necessary.

When using MicroSD, writes. “the card is protected”, the problem may be when writing files exceeding 4 GB in volume. You can fix the error by changing the FAT32 file system to NTFS.

If the memory card writes. a reading error, most likely that the frames existing on it were made by other equipment.

The computer does not see the SD memory card

SD cards will remain a popular storage format for a long time to come. The standard has become very closely entrenched in the photo and video equipment market, and therefore the need for card readers has been, is and will continue to be. From time to time, users encounter a problem with the operation of SD cards (or card readers) in computers running Windows 10. The card is inserted into the appropriate port, but the computer cannot recognize it and the SD card is not displayed in Explorer. This is a very common and rather unpleasant problem, which, fortunately, is very easy to fix in the vast majority of cases. In this article, you will find some tips to help you if your computer does not see your memory card.

Although in this manual we are mainly talking about SD cards (the ones that are larger), the instructions are also relevant for microSD cards. Modern computers (Surface tablets, for example) are often equipped with microSD slots lately. The tips in this article also apply to these devices.

The computer or laptop does not see the memory card. what to do

First you need to make sure the card is working. To do this, insert it into another device with a slot for SD (or microSD using an adapter) cards. It can be a camera, camcorder, second computer, tablet, smartphone or any other device equipped with a corresponding slot. If the memory card is not recognized in this device or works intermittently, then it is either damaged or needs cleaning the connectors.

Take a cotton ball, “ear stick” or piece of cotton wool, lightly soak them in alcohol or an appropriate cleaning agent (in theory, ordinary water will work, but either a special cleaning agent or simple alcohol will do the best for the task) then lightly walk over the metal contacts on back of the memory card. Important: do not pour liquid onto the card (you only risk killing it) or insert it wet into the port. Make sure the contacts are dry and clean, and then try again to connect the memory card to the computer.

Check for dirt in this area of ​​the memory card or adapter you are using.

If after this procedure the memory card works in other devices, but does not work in the computer, then it makes sense to also clean the slot itself. Perhaps there is too much dust in it, which prevents the computer from reading information normally. You can clean the memory card slot in a computer or laptop using compressed air.

Another tip: make sure you insert the card the right way round. The computer should show which side to insert the card. Some slots use a latching mechanism to secure the card into the slot. In such a computer, you cannot insert the card upside down as it will not lock. Other computers may not have this mechanism, so make sure the memory card is installed correctly. Do not use force when connecting or removing a card, as you risk breaking the slot, card or locking mechanisms.

Let’s say the memory card is working, you insert it in the correct direction, the slot in your computer is clean, but the PC still does not see the SD card. In this case, there are some more tips that should help.

Check if the memory card is detected in the disk management interface. If a letter is not assigned to the memory card, the drive will not appear in Explorer, although both the slot and the memory card are physically working.

  • Unplug any flash drives from your computer and leave only your SD card. This will help streamline the process.
  • Click Win X and select Disk Management.
  • At the bottom of the utility interface, your hard drives and SSDs will be displayed first. They are labeled as “Basic”. Any removable drives (flash drives, memory cards, external hard drives, and so on) are marked as “Removable Device”. See if it’s on the list. Disk Management should display the type of media, its size and the label “Online”. this means that the card is working properly.
  • Check if a letter is attached to the card. If there is no letter ((G :), for example) next to the name of the map, then it is because of this that it is not displayed in Explorer.
  • Right-click on the map and select Change Drive Letter or Drive Path. In the window that appears, click Add, and then select the Assign Drive Letter (A-Z) option. Choose any letter you like and click OK.
  • After that, the system should inform you about the new found disk and the memory card will appear in Explorer.

Check if the memory card slot is enabled in the BIOS settings of your computer. Sometimes it happens that the card reader on the PC motherboard is simply disabled for some unknown reason. You can check this by simply diving into the BIOS settings. Restart your computer and during startup press F2 / Delete (or another button chosen by your manufacturer) to get into the BIOS. Each computer has its own BIOS (UEFI), which differs depending on the manufacturer or motherboard model, so we cannot publish all the options here. You need to find the section with ports and devices (Onboard Devices / Miscellaneous Devices and so on), and then look for something like “Media Card Reader”, “SD Reader”, “Enable ExpressCard” and so on. Make sure it is turned on, then save the settings, restart the computer and try again to connect the memory card.

The checkbox that is responsible for activating the built-in SD card slot in the BIOS of Dell computers. If the checkbox is not checked, the port will not work.

In the case of desktop computers, it is also possible that the SD card slot on the front of the case is not connected to the computer’s motherboard. Here you will have to open your case (before that, completely disconnect the computer from the outlet) and see if the wire is connected from the front panel of the case to the motherboard. The wire with a 9-pin connector must be connected to the appropriate comb on the motherboard.

Sometimes the source of the problem may be an adapter that does not work as expected. This is the case if you are using an SD adapter for microSD cards or other format cards paired with an adapter. Of course, an extra adapter is not always on hand, but this option is also worth considering if you can’t get your computer to work with a memory card. Fortunately, the adapters cost mere pennies and it will not be difficult to find them.

You can refer to the system’s built-in diagnostic and troubleshooting methods. Perhaps Windows itself will be able to find the cause and successfully fix it.

  • Click Win I and go to Update & Security.
  • In the left menu, click Troubleshoot. Find Hardware and Devices in the list. Click this item and then click Run the troubleshooter.
  • Wait while the wizard checks your system and reports the results. If he does not find anything, proceed further along this instruction. If the diagnostics still find something, apply the tips suggested by it, and then try to reconnect the card to the computer.

The next option is to turn off and on the card reader. Perhaps a trivial bug in the operating system or controller led to the failure of the card reader.

  • Press Win X and select Device Manager. Alternatively, you can press Win R and enter devmgmt.msc.
  • In the list of devices, look for Host Storage Adapters. This is your SD reader. Expand it and the adapter controller should appear on the screen. This can be a Standard SDA Compliant SD Host Controller, some Realtek PCIe CardReader, or an adapter from another manufacturer.
  • Right click on the adapter and select Properties. Go to the Driver tab and click the Disable device button. Confirm Action.
  • Then reopen the properties and turn the card reader back in exactly the same way.

If a peculiar reboot of the adapter does not help, you can try reinstalling or updating the card reader driver. Go to your manufacturer’s website and check if there is a new version of the driver. If there is, download and install it. Previously, you can remove the old version of the driver in the Device Manager.

  • Press Win X and select Device Manager.
  • Expand Host Mass Storage Adapters, then click on the adapter and select Properties.
  • On the Driver tab, click Uninstall device. Confirm deletion.
  • After that, download the driver on the manufacturer’s website and install it. Restart your computer and then try plugging in the card again.
  • If the slot stopped working after a recent driver update, click Roll Back on the Driver tab to revert to the previous version of the driver. Please note that the function to roll back a driver to a previous version will only be available if you have updated the driver at least once. If there are no previous versions of the driver in the system, the Rollback button will be grayed out, as in the screenshot below.

It should be understood that none of these methods will help if your computer slot is damaged or broken. If the memory card works in other devices, but is not detected in your computer in any way, even after all these dances with a tambourine, then you need to contact a specialist who will check the physical health of the port, repair or replace it. To extract information from the card, insert it into another device (the same camera), and then connect it via a USB cable to your computer, or transfer the data you need from another PC.

We hope these tips will help you fix the problem and you will not have to contact a service center, repair your computer or change a memory card.

Malware in the operating system

Faced with the problem of identifying a Micro SD drive, you may not even suspect that malware, the so-called viruses that can block USB ports and prevent the computer from working with your memory card, may be to blame.

In this case, it would be best to conduct a full system scan with your antivirus program, or resort to free antivirus programs that can help you with this.

One of these I will advise you is Dr.Web CureIt!

The program is absolutely free and is intended only for scanning and finding virus programs and removing them.

To download this program, go to the official Dr.Web website at the link

Download the program and run a scan.

After the end, remove all found malware and after restarting the computer, try to connect the Micro SD card again.

Assigning an already assigned partition letter

This type of problem is quite common. This happens when the SD card is connected to the computer, the system assigns it the same letter as the existing partition, because of this, a conflict occurs and we do not see our flash drive in the list of computer disks.

In order to fix this type of problem, open the “Computer Management” section, the method for opening this section is described above.

After getting into the “Disk Management” section, we need to find our USB flash drive, focus on its volume, select the disk that matches the volume of our Micro SD card. Click on it with the right mouse button and in the drop-down menu select the item “Change drive letter or path to disk.”.

In the window that opens, select the letter for this section and click “OK”.

Done, we have assigned a letter to our section, now we check its presence in the explorer.

The computer does not see the Micro SD memory card. what can be done?

Today, the method of storing data on portable flash drives has gained quite a lot of popularity. And now all manufacturers of flash drives are fighting to create a flash drive that is as small in size and large in memory as possible, the leading positions in the minimum size are occupied by Micro SD cards.

Micro SD flash cards are by far the smallest mass storage devices in production.

Due to their very fragile structure, these drives quite often become unusable as a result of physical damage, or improper shutdown of work with such flash drives.

It is not uncommon when, after a short period of working with a card, it ceases to be read or is not detected at all by devices, so you cannot rely on the long-term operation of such a drive. I advise you to use the Micro SD card as a space for work, and not for permanent storage of information. Although every day the manufacturers of such SD cards improve their durability, and more and more bring them closer to the possibility of using them for permanent and long-term storage of information.

The reasons why the computer may not detect the Micro SD card:

  • Hardware problem.
  • USB flash drive breakage.
  • Assigning an already assigned partition letter.
  • File system conflict.
  • Malware in the operating system.

If your Micro SD card is no longer detected by a phone, camera or other device, then you need to remove it and insert it into your computer to diagnose, identify and fix the problem.

Let’s move on to examining and eliminating the most common causes of malfunction of such a flash drive.

Hardware problem

If you are trying to connect your SD card to a computer through an adapter or through a card reader, and nothing happens, the first thing to do is to check the functionality of these pairing devices.

If you use a card reader to connect the card, then try to insert a known working Micro SD card into it, if the known working card was not detected either, in this case, check and reinstall the driver of the card reader. If after all the attempts made, nothing has changed, then most likely the problem is in the card reader.

If you are using a laptop, then most likely you are trying to insert an SD card through an adapter, directly into the laptop’s built-in card reader. If, when using this method of connection, nothing happens either, then I recommend first checking the driver for the built-in card reader, and then check the adapter for operability.

Drivers for card readers can be downloaded and installed from the manufacturers’ official websites, if you have a portable card reader that connects via a USB port, then download the drivers from the manufacturer’s website. In the event that you use the built-in laptop card reader, then you can download the drivers from the official website of your laptop manufacturer.

In order to check whether the driver of your card reader is defined by the system, you need to open the “Device Manager”, for this we press the Win R key combination and in the “Run” line that opens, enter the command “devmgmt.msc”.

The “Device Manager” window will open in which you can see the devices on which the driver is not installed. Such devices will be marked with a yellow exclamation point triangle. If there are no such devices, then open the “Portable devices” section and make sure that the computer has detected the card reader itself, in order to discard the option of a non-working device.

How to check if the Micro SD card is detected on the computer?

In order to understand whether your computer has detected your Micro SD card, you can use 2 methods.

The first way. Open my computer and check the connection of the new partition. If you have a new disk, then the flash drive is identified.

Second way. If nothing appears in the explorer, then it is worth checking whether the computer at all determined that an SD card was connected to it. To do this, go to my computer, right-click on the computer and select “Control” in the drop-down menu.

After that, the Computer Management window will open, in it there is a menu on the left side. We need to select the “Disk Management” section.

In the displayed statistics, we can see all the drives connected to the computer, determine their volume, or set the letter of the partition.

camera, does, card

If you did not see your SD card in this list, then read the following reasons and their solutions.

File system conflict

It is not uncommon for a flash drive to be detected, but it does not work to open it. The reason for this may be a conflict of file systems or a damaged file system of the Micro SD card itself. If the data on the flash drive does not matter to you, then you can try to format it to the NTFS file system.

To do this, right-click on the USB flash drive and select the “Format” item in the drop-down menu.

In the formatting window that opens, in the “File system” section, select NTFS. set the Volume label and click the “Start” button.

Thus, we formatted the Micro SD card to NTFS format. after which you can open it.

USB flash drive breakage

In the event that you have checked the performance of the above devices and made sure that they are in good working order, then it is worth checking the Micro SD card for physical damage, cracks, chips, deformation or damage to the outer layer, since such a flash drive consists of many small tracks, which are easy to scratch and tear.

Try to connect it to any device, a smartphone, camera, etc. If the flash drive is not detected in any device, then most likely it is physically damaged and cannot be repaired. You may be prompted to contact the service center, only the presence of important information on the card.

As you can see, there are many reasons why your computer does not see the Micro SD card, therefore it is impossible to unequivocally answer the question “Why does my computer not see the memory card?”, Since this can be caused by various problems. In order not to make a mistake and solve the problem, it is worth taking turns to do all the steps described in this article.

Also, do not forget that when formatting, all information from the flash drive will be deleted.

And I advise you not to store important information on drives of this type, as they most often refuse to work due to a very fragile structure. Use this type of drives for direct work with files, saving them in more reliable places.

Memory card incompatibility with the phone

Memory cards differ from each other not only in size and manufacturer, but also in type, class (operating speed). As a visual illustration, I cite a photo of a package from a well-known manufacturer: pay attention to the SDXC marking.

Actually, knowing what type of card your card is, you can easily find out whether the phone can work with it: just open the specification for the device (it should be included with the new device, or you can use the Internet. Sometimes this information can be found on the package).

By the way, relatively old phones cannot support memory cards of all sizes. Take a look at the packaging photo of one Samsung budget phone. This point should also be clarified.

You can learn more about the types of memory cards, classes, etc. from this note:

Reasons why the phone does not see microSD

MicroSD is not formatted (or why the error “cannot connect SD” appears)

There are many varieties of such an error (depending on the version of Android, and the brand of the phone itself (one of the versions is shown in the screenshot below)).

Most often, the error appears due to the fact that:

    The SD card is formatted into some unfamiliar file system for Android (for example, NTFS. The computer will see such a card, but the phone, most likely not);

  • if the size of the SD card is more than 32 GB, then most likely it is formatted in exFAT (at least many SD cards come with it by default). Not all smartphones support this file system;
  • the file system was simply damaged. If such a memory card is connected to a computer. then in the properties you will see FAT 32 (for example), and RAW.
  • To fix such problems, it is enough to format the SD card in FAT 32 (except for those cases when the memory card is incompatible with the device; more on this below in the article).

    Why the phone may not see the microSD card, and what to do about it [Android]

    Good day!

    There is never a lot of memory (especially when it comes to the phone)! And often to free up a little internal memory, or to transfer information from one device to another. we have to resort to SD cards.

    And, unfortunately, red tape and problems with them are no less than with many other drives (the same USB flash drives, for example).

    In this article, I want to focus on one popular problem: about the visibility of microSD cards on phones. There are a lot of questions about them, and I decided to combine some of them (the most common) into one instruction. I think the note will be very useful to everyone who encounters a similar problem.

    Poor contact (e.g. contact oxidation, dust)

    In some cases (if the phone has been dropped; used in dusty rooms or where there is high humidity, etc.), it may become so that the copper contacts of the memory card will “poorly” contact the contacts of the phone. As a result, the device simply will not see it, as if it had not been connected.

    In this case, you can recommend removing the memory card from the device and wiping the contacts with an alcohol wipe. Please note that this must be done carefully: the thickness of the card is not that great and it can be easily damaged.

    Note that it is also possible that there is a problem with the tracks on the phone. Cleaning them, as a rule, is much more difficult (in many ways it depends on the model of the device). In some cases, it is better to contact the service for this.

    When can we say that there is a hardware problem with the phone:

    • he does not see 2-3 different SD cards (which work on other devices: PC, laptop, etc.);
    • you have checked that the data of the SD cards (which you are connecting) are compatible with your device, and they are formatted in the correct file system (most often FAT 32);
    • you reset the device to factory settings (how to do it), but it did not give any results.

    The memory card has been damaged

    Most often, a memory card becomes unusable due to mechanical damage (for example, many put the card in their. and then sit down or turn unsuccessfully). Also, there are often cases when users are in a hurry to quickly connect / disconnect the SD card to the phone and by forcefully pressing on it, “force” it to crack.

    In general, first, pay attention to the appearance of the card: it is not at all necessary that it will be broken in half (as in the photo above). There are often cases when only a small edge of the card is “chipped off”.

    When, in general, we can say that the SD card is damaged (assuming that there are no visible traces on it):

    • you connected it to 2-3 different devices (PC, phone, laptop) and none of them recognized it (did not see it);
    • cleaned the copper contacts with an alcohol wipe, but this also did not work;
    • tried to format it on a special PC. utilities (which in some cases “see” even those flash drives / SD cards that Windows does not display);
    • it is highly desirable to also believe the officers. the website of the manufacturer of your SD card (it may contain special recovery utilities).

    If there were memorable photos, videos (and other files) on the memory card. do not rush to throw it away. In large cities, there are services that professionally deal with data recovery (although it is not cheap, but still.). It is possible that they will be able to pull something from your card.

    How to format a memory card to FAT32

    1) Connect SD card to PC and go to “This computer”. (you can press the WinE combination, and after the explorer opens, select it in the left menu, see the example below)

    2) Next, on the SD card, right-click and select “Format.”.

    3) In the next step, specify the FAT32 file system and click on “Start”.

    Important! Formatting will destroy all data on the drive.

    4) If everything went well. a message appears indicating that formatting has been completed. Can take out microSD and connect to phone.

    If it was not possible to format using Windows tools (for example, the OS may freeze when accessing the drive). I recommend trying the specials. utilities. For example, JetFlash Recovery Tool or SD Formatter can format even faulty and poorly performing SD cards. I recommend trying (I give a link to them below).

    JetFlash Recovery Tool main window. screenshot of work

    Software error

    Perhaps the article should start with the most obvious. Often, due to various software failures, some applications may incorrectly start to detect the memory card (and, accordingly, it will not work with it. By the way, it may become so that it will not be displayed at all in the Android settings).

    The first thing to do in this case. just restart the smartphone (note: to do this, just hold down the power button for 3-5 seconds until the corresponding menu appears, example below).

    For a forced reboot of the device (for example, due to a “dead” hang). you need to hold down the power button for 10 seconds.

    By the way, if the phone starts to freeze after connecting the memory card (slow down and behave unnaturally). there is a great risk that the memory card has become unusable (ie he sees it, tries to work with it, but it “does not answer”.). In this case, try removing the SD card and connecting it to the PC (for a more detailed check.).

    Standard procedure

    First, we will consider the basic steps to eliminate the malfunction, and then in the article I will tell you in detail about all possible causes, methods of correction.

    If the phone for some reason does not see the memory card, you should:

    • Perform a normal reboot (turn off-turn on). This sometimes helps to get rid of software glitches. Did not help? Let’s move on to the next solution;
    • We turn off the smartphone, remove the back cover, remove the battery and wait a couple of minutes. Then we return everything to its place and check the operability of the microSD:
    • Suddenly the previous option did not work, we try to remove the “card”, check the integrity of the contacts and put it back tightly:

    As soon as you do the above manipulations and do not get a positive effect, proceed to viewing the methods below.

    Question answer

    Further, useful information will be presented in the format of answers to frequently asked questions from readers of various forums and thematic resources. I have collected the most valuable recommendations. Perhaps among them there is a solution for you.

    Resolving Micro SD Card Problem in IP CCTV Camera

    But a week later I noticed that the transferred files were gone. I opened the explorer. all the folders are in place, but they are empty. And where the information has remained, it gives an error when trying to reproduce. The strangest thing is that I rearranged the card into the old gadget. everything opens and displays without any problems. By the way, after a reboot, sometimes the problem disappears, but not always. Is there a defect in the phone? What should I do, advise.

    Wrong SD format

    If the phone does not see the memory card, it is likely that it has the wrong file table format or that it is damaged.

    • Memory markup failure;
    • The user has formatted with incorrect settings;
    • MicroSD previously worked with a file system unknown to the gadget, has specific markup that Android does not accept.

    Most modern flash drives with a volume of more than 32 GB are marked in exFAT format, which not all phones “see” (especially outdated models). Therefore, if your external memory is of a similar size, then you should first copy important data to your computer, insert the card into your smartphone / tablet, switch to Recovery mode, select the action “Wipe cache partition” to format and create a table of FAT32 files. It is perceived by all devices without problems.

    But I would recommend a simpler and more reliable option. using the app SD Formatter, which is installed on the laptop. You will need a card reader. I recommend watching the following video explaining the procedure for working with the program:

    You can perform the procedure and built-in Windows tools. I already talked about them in the article. link. But now I will repeat myself again.

    • You can connect a phone to a computer via a cable, but I would advise you to use a card reader for the purity of the experiment. Anyone will do. For example, I have one like this:
    • We insert a card into it directly or through an adapter (depending on the presence of certain slots in the reader):
    • When connected to a PC, go to “Explorer” (My Computer) and there should be a new disk displayed. Click on it with the right mouse button and select the “Format” command.
    • A window will open where we specify the FAT file system (exFAT). We do not change the other parameters, we immediately click on the button to start the procedure.

    Another option very rarely helps. select the type of FS. NTFS. Some devices can work with it. It is worth trying if all else fails.

    What if there is no computer nearby? You can use the built-in Android tools. But not all versions have this functionality. You need to go to “Settings” and in the “Memory” section find the line “Format SD” (it can also be called “Clear SD”):

    Do not forget that in this case all data will be completely deleted with a minimum likelihood of subsequent recovery. Please note that there is also a button for safe removal in the specified menu. This is for good reason. you need to resort to this event every time you want to remove the microSD card. So you will not harm the information stored on the carrier and extend its life. But, alas, many are accustomed to using “hot-fetch” right in the process. This is not entirely correct and may cause crashes.

    Why is it critical?

    In most cases, the phone has its own internal storage, and an external card is used to increase the amount of “storage”. Imagine that we have specified third-party media as the main location for saving photos, videos, applications in the device’s settings. But it suddenly stops working correctly, the system does not see it, and all data is sent to the integrated memory. And when there is not enough free space, often, the gadget starts to “glitch”.

    Let’s say you decide to remove the defective card and replace it with a new one. But the problem may not go away. You didn’t expect that, right? Such things can make device owners pretty nervous. I think that’s enough theory and assumptions, it’s time to move on to specific steps. There will be a lot of them, for all occasions.

    The phone stopped seeing the memory card: a failure at the software level

    Diagnosis: Certain Android app does not recognize external storage, while others do it without issue. recording, playback proceeds as expected.

    What to do? Most likely, a different location for saving data (internal “disk”) is specified in the utility settings. It is enough to open the parameters and make the necessary changes. This behavior often helps to eliminate defects in the standard software “Camera” and “Gallery”.

    The computer does not see the SD card either

    Situation: we connected a mobile gadget to a PC via a USB cable, the phone screen displayed a choice of connection modes, indicated “Mass Storage”, but the new “storage” was not displayed on the laptop.

    The solution is simple: just disconnect the device and then plug the cable back into the laptop, but now you need to select the “Media Device” (MTP) mode.
