Troubleshoot problems from Microsoft
Windows 10 already has a computer troubleshooting utility installed by default. Sometimes it can help solve the problem with the display of USB media when connected to a computer. If you have such a utility, then download it from the official Microsoft website.
Perform troubleshooting according to the following instructions:
- Run the diagnostic and troubleshooter. Here you will only need to click on the “Next” button.
- Wait while the program scans your computer for system errors.
- When the scanning procedure is over, you will be able to read the detailed report. To fix the detected problem, you only need to name it by its name.
- The procedure will begin to correct the problem. Wait for its completion and do nothing.
Infection with viruses
In such cases, the system will usually show the connection of the media itself, but you will NOT be able to open it (get an error) or when you open it, you will get an empty directory. If so, then be sure to scan your computer using Special anti-virus programs. As a rule, after scanning, you will be able to delete detected threats or quarantine them.
In the new editions of Windows 10, Windows Defender Standard is a powerful enough program for finding and eliminating viruses. Instructions for using it in this case will look like this:
- Open Windows Defender. This can be done by invoking the search term using the magnifying glass icon in the taskbar. In the search term they will register “Windows Defender Security Center”. Choose the appropriate one among the issuance options.
Now, in the antivirus interface, click on the “Virus and threat protection” tile.
Find the words “Start new advanced scan”. Click on it.
Select a test option. If there are real reasons to suspect a virus infection, then it is better to put a marker opposite the “Full scan” option. After that click on the button “Scan now”.
What to do if Windows 10 does not see your USB stick
In fact, there can be a lot of problems due to which the operating system does not see your flash drive. First of all, it is recommended to check whether the USB flash drive itself and the ports into which you insert it are working properly. The best way to do this is by connecting the media to a second device via a SIMilar USB port. If everything is fine there and the device is displayed, then the device is physically working properly. If you suspect that the USB port on your computer is faulty, try inserting another device into it. Provided that it connects and displays normally, proceed to solving the problems described below.
Incorrect USB drive letter
If the letter that designates your flash drive in the system is the same as the letter of any other device, then the system SIMply will not be able to display it correctly. In this case, you just have to try to change the drive letter manually. This is done as follows:
- Click on the magnifying glass icon in the taskbar and enter the value “Computer Management” there. Open the item displayed in search results.
USB flash drive recovery
This option is very SIMilar to the previous one, since it involves checking and correcting errors on the media using the utilities built into the system:
- Open “This computer” to Access all drives in the system.
- Right-click the icon of the faulty device and select Properties from the context menu.
- Next, open the “Service” tab. Here you need to use the “Check” button.
- It will check the media for errors. If any are found, the system will prompt you to eliminate them.
Deleting Autorun.Inf File
If the antivirus check did not give clear results, you can try to find the Autorun.Inf file on the USB flash drive and delete it. Unfortunately, you can use this option only if you can open the USB flash drive and it is displayed in Windows Explorer.
Do the following:
- First, you will need to make sure that all files on the flash drive that have the “Hidden” attribute are displayed. Viruses usually assign this attribute to all files on the medium. In the Windows taskbar, click on the magnifying glass icon and enter in the search term “Show hidden files and folders”. Select the desired result.
Sometimes it happens that after installing updates, the system stops correctly displaying USB-drives. In this case, you can fix the problem using the USBOblivion program. It is recommended to back up the registry before starting the procedure. This can be done using third-party programs such as CCleaner.
It is recommended that you remove all flash drives from your computer before using USBOblivion. Now do the following:
- Run USBOblivion. If you downloaded it from the official site, then you will have an archive with two software versions. for 32-bit and 64-bit operating systems. Select the Appropriate file for OS and run it.
- In the window that opens, tick all the boxes that are located at the bottom. These are “Do real clean” and “Save backup”. Then you will need to use the “Clean” button.
Windows 10 does not see USB stick: solution to the problem
Users of Windows 10 and the second versions of this operating system face a problem when the flash drive functions normally and is connected to the computer, but the system does NOT display it in any way. To cope with this problem, you need to find out its cause, and then look for ways to eliminate it. The following article will discuss popular reasons why a USB flash drive may NOT appear in Windows 10 when connected. Each problem will be given instructions on how to resolve it.
- What to do if Windows 10 does not see your USB stick
- Infection with viruses
- Deleting Autorun.Inf File
- USBOblivion program
- Outdated drivers
- Troubleshoot problems from Microsoft
- USB flash drive recovery
- Incorrect USB drive letter
- USB formatting
- Incorrect BIOS settings
- Incorrect controller firmware
It often happens that the system cannot open a USB flash drive, but at the same time offers to format it. If there is no fundamental data on the medium, then it is better to agree and format it. If there is something important on it, then try to extract this data using Special Programs. Provided that it was possible to obtain this data, format the media, since the information from it can still be restored using Special programs.
The system may not be indicative of a notification that the flash drive needs formatting, or you can accidentally disable this notification. Then formats the media according to the following instructions:
- Open “This PC” and right-click on the faulty media. There click on “Format”.
A window with formatting settings will open. Here you can only disable the “Quick” item, which is located in the “Formatting methods” block. However, in this case, the files on the flash drive will be very difficult to recover.
How to check if 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 ways.
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 on the left side there is a menu. We need to select the “Disk Management” section.
In the displayed statistics, we can see all the drives connected to the computer, determine their size, or set the partition letter.
If you did NOT see your SD card in this list, then read the following reasons and their solutions.
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 minimum sizes are occupied by Micro SD cards.
Micro SD flash cards are by far the smallest mass storage devices that have been put into production.
Due to their very fragile structure, these drives quite often become unusable as a result of physical damage, or incorrect shutdown of work with such flash drives.
It is NOT rare that after a short period of work with a card it stops being read or is not detected at all by devices, so you cannot rely on the durable operation of such a drive. I advise using the Micro SD card as a space for work, not for permanent storage of information. Although every day the manufacturers of such SD cards are improving their durability, and are increasingly bringing them closer to the possibility of using them for permanent and long-term storage of information.
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 your phone, camera or a second 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 a malfunction of such a flash drive.
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 also NOT identified, 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 off-site. 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 detected 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 triangle with an exclamation mark. If there are such devices, then Expand the section “Portable devices” and Make sure that the computer detects the card reader itself, in order to discard the option NOT working device.
File system conflict
There are NOT rare cases when the flash drive is detected, but it does NOT work to open it. The reason for this may be a file system conflict 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 “Format” 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. Then you can open it.
Malware in the operating system
Faced with the problem of determining the Micro SD drive, you may NOT even suspect that malware, the so-called viruses, which 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 software, which 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 https://free.Drweb.ru/cureit/
Download the program and run a scan.
After finishing, remove all found malware and after restarting the computer, try to connect the Micro SD card again.
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, That are easy to scratch and tear.
Try to connect it to any device, 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.
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 cannot see our flash drive in the list of computer disks.
In order to fix this type of problem, open the “Computer Management” section above, the method for opening this section is described.
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 size 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.”.
A window will open in which we need to click the “Add” button.
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.
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 may be caused by various problems. In order NOT to be mistaken and to solve the problem, it is worth taking turns to do all the steps described in this article.
So do not forget that when formatting, all information from the flash drive will be deleted.
And I advise everyone that I could not store important information on drives of this type, as they most often refuse to work because of a very fragile structure. Use this type of drives for direct work with files, saving them in more reliable places.
What to do if a Windows computer does not see a USB flash drive or external hard drive
First, figure out what exactly the problem is: with a computer, an adapter (if connected via a cable) or a drive. Try connecting your USB device through different ports. If it does not help and you are using the cable, try replacing it with a spare one. If unsuccessful, check if the drive opens on other computers.
If the device works on another PC or you have no way to check it
Connect a hard drive or USB flash drive to your computer and follow these steps in order. If the first does not help, go to the next and so on.
1. Please use Microsoft’s USB Troubleshooter. To do this, download the program from the official website of the company and run it on your computer. Then follow the prompts on the screen for the utilities to analyze the system and try to fix problems automatically. Reconnect the drive when finished.
2. Check the drive settings in the Disk Management menu. First, open a command prompt window (Windows R keys), then type diskmgmt.Msc in it and press Enter. Carefully read all system warnings so as not to accidentally format the drive or change the data recorded on it.
If you see a disk without a volume label in the Disk Management menu, this may be the cause of the problem. Then right-click on the disk and Assign a letter to it using the appropriate option in the context menu.
Then restart your computer. the desired drive can finally appear in the explorer.
3. Check your hardware settings in Device Manager. To open it, type devmgmt.Msc at the command line and press Enter. If you see a non-working device (with a question mark or an exclamation mark) in the manager, an update may help.
Right click on this device and click “Delete”. In the top menu, click “Action” → “Update hardware configuration”.
4. Install the latest Windows updates. Without them. especially in Windows XP. the operating system might not be patched to work with modern USB drives. In addition, it will not be superfluous to update your drivers.
Why the computer does not see a USB flash drive or external hard drive and what to do about it
There are many reasons why a computer might NOT detect a storage device. Life hackers lists the most popular ones along with the SIMplest ways to solve the problem.
Why the computer does not see the USB device
Usually, suspects in this case are software failures, incorrect operating system settings, outdated drivers, malfunctions of computer USB ports, adapters or drives.
Depending on the reasons, in each case the problem manifests itself in a different way. It happens that the computer does NOT react at all to a USB flash drive or hard drive. In other situations, the sound of connecting a new device is heard, but the drive icon does not appear in the explorer. And sometimes the computer just freezes right after contact with a USB device.
If the other PC doesn’t see the drive either or all of the above tips Didn’t help
In this case, the problem is most likely in the drive itself.
If you have a flash drive, not a hard drive, you can use special utilities to fix software errors. Such software can usually be found on the manufacturer’s website. For example, JetFlash Online Recovery is for Transcend drives. And USB Flash Drive Online Recovery is for ADATA flash drives. But please note that during the recovery process these utilities erase all data from flash drives.
What to do if Mac does not see a USB flash drive or external hard drive
On Apple computers, the verification procedure is somewhat different, but it follows approximately the same aLGorithm. We will assume that you have already tried restarting your computer, disconnecting and connecting a USB flash drive, and also made sure that the connection is reliable. If this does not help, you need to do the following:
1. Check the drive for “disk junk”. Open the built-in tool for working with disks (“Programs” → “Utilities” → “Disk Utility”) and check if the problematic flash drive is displayed there. If the drive is still visible, try reformatting it by clicking the “Erase” button, and then reconnect. Keep in mind that all data from the flash drive will be permanently deleted.
2. Check the drive in System Information. Dedicated Mac Diagnostic Tool provides detailed information on all software and hardware components of your computer, including USB devices. Open the Apple menu, then hold down the Option key and click System Information and navigate to the USB section of the menu that appears.
The computer does not see the USB stick. It doesn’t matter, everything is very SIMple! Windows 10 does not see a USB flash drive after updating or installing (it will work for Windows 7, 8 and Windows 10)
Many users have encountered the problem of NOT displaying USB drives after upgrading to Windows 10 from previous OS, or after SIMply installing updates on an already installed Windows 10. It often happens that USB drives are NOT visible only via USB 2.0 or USB 3.0. i.e. It can be assumed that USB drivers are required. However, in fact, this behavior is often caused by drivers, but by incorrect entries in the registry in previously connected USB drives.
In this case, the free USBOblivion utility can help, which removes from the Windows registry all information about previously connected flash drives and external hard drives. Before implementing the program, I recommend creating a Windows 10 restore point
Disconnect all flash drives and other USB storage devices from the computer, run the program, Check out the Perform a real cleanup and Save the undo reg file, then click the Cleanup button.
After cleaning is complete, restart your computer and connect the USB flash drive. with a high probability, it will be detected and become available. If there is, then try also to go to the device manager (through the right click on the Start button) and Follow the steps to remove the USB drive from the Other devices section and then update the hardware configuration (described above). You can download the USBOblivion program from the Official developer page: www.Cherubicsoft.com/projects/usboblivion
But, in relation to Windows 10, another option is also possible. Actual incompatibility of USB 2.0 or 3.0 drivers (as a rule, then they are displayed with an exclamation mark in the device manager). In this case, the recommendation is to check the availability of the required USB drivers and chipset on the official website of the laptop or PC motherboard manufacturer. At the same time, I recommend using the official sites of the manufacturers of the devices themselves, and not the sites of Intel or AMD to find such drivers, especially when it comes to laptops. Also, sometimes updating the BIOS of the motherboard helps to solve the problem.
How to remove drivers for all USB devices
- Turn off the computer and Disconnect all USB storage devices (and not only) (flash drives, external hard drives, card readers, webcams, etc. The mouse and keyboard can be left on, provided that they have a built-in card reader.
- Turn on your computer again.
- Download the DriveCleanup utility http://uwe-sieber.De/files/drivecleanup.Zip (compatible with Windows XP, Windows 7 and Windows 8)
- Copy the 32-bit or 64-bit version of drivecleanup.Exe (depending on your Windows version) to the C: WindowsSystem32 folder.
- Run command term as administrator and type drivecleanup.
- You will see the process of removing all drivers and their entries in the Windows registry.
When the program finishes, restart your computer. Now, when you insert the USB flash drive, Windows will install new drivers for it.
Update 2016: It is easier to perform the operation to remove mount points for USB drives using the free USBOblivion program, as described above in the section on non-working flash drives in Windows 10 (the program will work for other versions of Windows as well).
Recovering a flash drive through the command term of windows 7, 8 or 10 (Chkdsk)
The last method, which will be described in this article, is a way to restore a flash drive after a command period using Chkdsk. By the way, in this way I mainly reanimate flash drives that refuse to work, so to speak, the last stage in the battle # 128521;
Updates required for the flash drive to work in Windows XP
Let’s briefly list the main updates of Winows XP, without which the operation of the flash drive can cause various errors.
- KB925196. incorrect identification of a flash drive or iPad.
- KB968132. errors occurring due to connecting multiple flash drives.
- KB817900. stopping the USB port after removing the flash drive and reinserting it.
- KB895962. stopping the work of flash-media after turning off the printer.
- KB314634. work only with old USB devices.
- KB88740. Rundll32.Exe error.
- KB871233. USB flash drive does not work if the computer has just woken up from sleep or hibernation.
- KB312370 (2007). USB 2.0 support.
Recovering data from a flash drive that the computer does not see
If in Windows disk management the computer displays a USB flash drive, but in the “Not recognized”, “Not initialized” state, and the partition on the flash drive is “Not allocated”, then most likely the data on the USB flash drive is damaged and you will need to use data recovery.
There are a few things to keep in mind that increase the likelihood of successful data recovery:
- DO NOT write anything to the flash drive you want to recover
- DO NOT try to save the recovered files to the same media from where they are being recovered
There is a separate article on how to recover data from a damaged flash drive: Data recovery software
If all else fails, and your computer still does not see the USB flash drive, and the files and data saved on it are very important, then the last recommendation will be to contact a company that is professionally engaged in file and data recovery.
Check if the computer sees the connected USB flash drive in “Disk Management
Start the disk management utility in one of the following ways:
- Start. Run (Win R), enter the command diskmgmt.Msc
, hit enter
- Control Panel. Administrative Tools. Computer Management. Disk Management
In the disk management window, note whether the flash drive appears and disappears when it is connected and disconnected from the computer.
Ideal. if the computer sees the connected USB flash drive and all partitions on it (usually one) are in a “good” state. In this case, it is enough to name it with the right mouse button, select “Make partition active” in the context menu, and, possibly, assign a letter to the flash drive. this will be enough for the computer to “see” the USB disk. If the section is faulty or deleted, then in the status you will see “Not allocated”. Try to name it with the right mouse button and, if such an item is found in the menu, select “Create a SIMple volume” to create a partition and format the flash drive (the data will be deleted).
If the label “Unknown” or “Not initialized” is displayed in the disk management utility for your flash drive and one partition is in the “Not allocated” state, this may mean that the flash drive is damaged and you should try data recovery (more on this later in the article). Another option is also possible. you have created partitions on a USB flash drive, which are NOT fully supported for removable media in Windows. Here the instruction can help you How to delete partitions on a USB flash drive
Driver conflicts in Windows XP
Some old drivers installed in Windows XP can lead to a variety of errors, including system freeze, incorrect assignment of a USB flash drive letter, and the appearance of the message “Insert disc”. The reason for this is that every time you connect a new device to the computer for the first time, the system installs a driver for it, which remains in the system even after the flash drive is disconnected. Connecting a new flash drive can cause a conflict due to the fact that the system will try to use the already installed driver Corresponding to a specific USB port, but a second USB drive. It is quite easy to fix this problem.
What to do if Windows 7 does not see a USB flash drive
Problems with identifying USB controllers arise not only in Windows XP, but also in the modern operating system Windows7. In this case, the cause of the problems is not related to the need to install updates, since the “seven” initially contains all the necessary applications for installing USB device drivers and working with them. However, Windows 7 has a bug related to writing incorrect information about USB controllers to the registry. A typical sign of this is a yellow exclamation mark is displayed next to the list of all USB devices in the “Universal Serial Bus Controllers” branch. Find in this section the keys named LowerFilters and UpperFilters. After that, just in case, create a backup copy of the registry and delete these keys. To create a backup, select the necessary section and select File. Export from the menu. Then open the “Device Manager” and delete everything from there devices, next to which there is an exclamation mark, and update the hardware configuration. The system will detect all devices and install their drivers. This method will fix problems not only with the fact that the computer or laptop does not see the USB flash drive, but also with the fact that problems in the operation of the second equipment connected via USB. The reasons for this problem can be varied. Windows 7 may stop seeing the USB flash drive after a power surge or after using applications to work with USB controllers. Sometimes the desire to reflash the controller of a flash device can turn into the most unexpected problems. In some cases, the use of such programs as ChipGenius, AlcorMP, JetFlash Recovery Tool can lead to problems related to the operation of USB devices in Windows 7. Chipgenius is designed to identify the manufacturer and other information in the device controller. Alcormp is an application for flashing flash drive controllers from most manufacturers. Jetflash Recovery Tool. a program for flashing flash drives from Transcend.
Tip # 1
Many people plug new devices into the USB ports on the front of the system unit. However, very often the front ports do not have a connection to the power supply, or there is power, but it is not enough for correct operation. What if the computer does not see USB in this situation? It is enough just to reconnect the device to one of the ports, which are located on the back.
Tip # 4
If the computer does not see information on your drive via USB, this may be due to the presence of malicious virus programs on the PC itself or the attached device. Here the solution is obvious: you should download a reliable powerful antivirus and conduct a full scan of both the computer itself and the drive.
Council number 5
This advice, rather, concerns those who cannot connect a USB flash drive. What if the computer does not see the USB drive, and you have already done everything described above? You need to be aware that sometimes there is a conflict between the file systems of USB devices and PCs. As a rule, on flash drives it is. FAT and FAT32 systems. Modern hard drives support NTFS. With the help of the “disk management” already familiar to us, you can change the file system type of the flash drive to FAT32 or NTFS.
Council number 3
What if my computer can’t see USB? Although it is very rare, it still happens that the ability to read data from USB devices is disabled in the BIOS. Most often, this is done in online stores and SIMilar institutions so that people, using their media, do not infect computers with viruses. If we are talking about a home PC, you should go into the BIOS, and then check the box allowing the motherboard to enable USB devices.
What to do if the computer does not see the USB device?
What if my computer can’t see USB? First of all, you need to make sure that there is NO damage to the same device that you need to connect. You can check this very SIMply: if everything is normal when you connect it to the second computer, then the device itself is working properly. Also, connect it to your PC, pay attention to whether the light (LED) comes on. If the computer does not see the phone, the USB ports and cable may be completely functional, but you need to check the settings of the device itself and confirm the possibility of data exchange between it and the computer (if this option is disabled, the device will NOT appear on your computer). This also applies to tablets, smartphones, MP3 players, and SIMilar gadgets.
Council number 2
Sometimes the system immediately detects a new data storage device, but displays a message that the device is NOT recognizable, and refuses to read the information. Most often, the problem lies, again, in insufficient power and is solved by connecting the media to the second port. However, in some cases there is a need to update the drivers. The easiest and most convenient way to do this is with specialized programs (say, Everest). It will help you find out the name of your board, and then download the Corresponding drivers from the official websites of the manufacturers.
It is also possible that the problem occurred due to the fact that Windows assigned the new device an already used volume label (letter). This is corrected using the control panel tools (right-click on the shortcuts “My Computer”, in the menu that appears, select the item “Control”). Case you will see the “Storage Devices” tab as well in it. “Disk Management”. It remains only to find the label of our device, press the right mouse button and select the “Path to disk” item (“Change drive letter”). In the window that opens, enter a new symbol. After that, the problem can be fixed.
Council number 6
Finally, you might just want to format the drive. This can be done if it is displayed in the list of connected devices. However, when formatting, all data stored on it will be permanently deleted.
