What to do when the flash drive does not open?
Flash drives have become an indispensable product that allows you to record sufficiently large amounts of information. When using them, various problems may occur. For example, this should be attributed to the situation when the computer sees a flash drive, but it is not able to read it. The reasons for this can be associated with the technical or software side of the drive. In any case, it is necessary to consider the main ways to eliminate issues.
Overall performance testing
When the flash drive does not open, it should be connected to another device connector. It is quite possible, the USB port simply does not work. You can try to connect to another computer or laptop. If it is impossible to consider the information and on it, there is a problem directly with the flash drive itself.
Inspect the surface of the product for various problems and defects. If they are, it is precisely that it is capable of becoming a problem. With visible defects, information recovery is possible. When the reason lies in electronic problems, it is not necessary to hope for it.
In a situation where the flash drive does not open, it is necessary to go through the next path: "Start" - "Control Panel" - "System" - "Device Manager". Here, we are especially interested in the section "Universal Serial Tire Controllers". Updated, by clicking the right mouse button and select the appropriate option. This is demonstrated in the screenshot.
It is recommended to use a secure device extraction when it must be removed from the port. As practice shows, there are no problems in the usual state. Problems appear in the case when it has been extracted to write files.
Using a conductor
You can open the USB flash drive in another way. It is recommended to use the conductor. To do this, you need to make the right click on the drive and choose the appropriate item. If you have time to open a flash drive in this way, you need to copy all the information and carry out the formatting process. After that, the data is rewritten back.
If you do not work out anyway, but the properties indicate the definition as a removable disk, you can take certain actions. They are composed of formatting. All data will be lost, but this is the only way to again be able to use the product.
Impact of the virus
When the flash drive does not open, you can assume its infection with a virus (or directly computer). Even after treatment, access can be blocked. This is due to the fact that malware creates the autorun.exe file with the autorun function. It should be deleted by special programs or manually through the registry.
Another option is to execute the "Sort" settings - "folder parameters" - "View", where "Show hidden files and folders" is set. When this is done, you just need to find the autorun file and delete it.
More and more users for storing and transmitting information are not used CD and DVD discs, but small and comfortable flash drives. The advantages are obvious: compactness, the possibility of a multiple recording, is not afraid of scratches like optical media. But on the other hand, it is just a device that cannot serve forever.
So, if you have connected a flash drive to a computer, and it is not read, try using the following ways to reanimate it.
Check for integrity
To begin with, check if the USB interface flash drive housing is normal. If he leaves on one side more than on the other, most likely, this is a problem with contacts. If you can, they can be soldered independently, but it is better to attribute a flash drive to repair.
Also check the device for mechanical damage: cracks, deep scratches, dents. Because of them, elements of the board were damaged, then the data recovery would be impossible. If water or moisture hit the USB flash drive, wait until it dies, and then connect to the computer.
Choose another port
Another reason why the flash drive does not open on the computer is the USB ports of the computer. It can simply be faulty - connect to another port. If you connect a USB flash drive to the ports located on the front of the system unit, try to do it from the back of it. The fact is that when assembling the system unit, the front USB ports could simply not connect to the motherboard.
This option is also possible - the flash drive does not have enough nutrition from the USB port. Disconnect all connected USB devices from the computer that you do not use: Web Camera, Printer, Scanner, and Other. This may be due to the fact that the low power power supply unit is installed in the system unit. For further use of the flash drive, it is better to purchase a USB splitter with additional power.
Change the letter of the disc
If the flash drive is still not read on the computer, then go to the menu "Start" . I click right mouse button on item "A computer" and from the context menu choose "Control" .
In the window, the computer controls on the left side is pressed "Storage devices" – "Disk management" . Here we are looking for a flash drive, if it has not decided, it can be thrown away.
If you have already created virtual disks earlier, then a flash drive has already been assigned the letter used. Click on the flash drive on the right mouse button and select item "Change the letter of the disk or the path to the disk" In the next window, click "Change" And choose the letter that is not yet used.
Problems with the opening of the flash drive also may arise due to drivers. Click the tab "Device Manager" and double press the mouse expand list "USB Controllers" . Here are the USB flash drive and click on it right mouse button. In the list you can choose or "Update Drivers" or "Delete" . Remove the USB flash drive and insert it back into the computer - the driver will be installed automatically.
If the automatic installation of the drivers did not happen, you can independently find drivers on the device instance code. If you have the Windows 7 operating system installed, look for the list "ENGLISH ID" .
Format the device
Another way that can be used if the flash drive does not open on the computer is formatting. To do this go to the folder "My computer" And right-click on the flash drive. From the context menu whether you select "Format…" .
In the formatting window, click on the button. "Restore default parameters" . Then mark the check box "Fast" and press "To begin" . Note that after this procedure, all data from the flash drive will be erased. But after quick formatting, you can try to restore, for example, using the Recuva program.
If everything went successfully, the flash drive should work. If formatting has not been completed, try moving low-level formatting for a flash drive using the Hard Disk Low Lewel Format Tool program.
Not read on the computer flash drive can also be due to viruses. Check it with an antivirus program. If after removing all malicious files, the flash drive does not open anyway, go "Start" – "Control Panel" – "Folders settings" .
On the tab "View" Mark the marker "Show hidden files, folders and discs" , click "OK" .
Now in the folder "My computer" Open the USB flash drive, find a file there. "Autorun.exe" And remove it.
These are all methods known to me, because of what the flash drive may not open on the computer. I think at least one of them will help you.Rate article:

Without flash drives it is impossible to imagine the work of users. On USB drives you can store gigabytes of information: Important files, documents, photos and more.
But it often happens that the flash drive begins to "climb", does not open or not defined on the computer.
Why the flash drive does not open: causes and troubleshooting
The reasons for which the USB drive "refuses to work can be somewhat.
The most common cause of flash drive errors is its clogging with viruses and malicious code. This is due to the fact that the drives are connected to computers, which in turn are infected.
Therefore, when connecting a USB drive to a computer, it is necessary to scan it for threats.
Do not forget that your antivirus should have fresh bases, otherwise it simply does not define the virus.
However, modern malicious programs are able to block access to the operating system to the flash drive, which makes it difficult to scan with an antivirus.
In this case, the virus will have to be deleted manually. This will require:
1. Go to the "Control Panel" of your computer.
2. Go to "folder parameters".
3. On the View tab, mark the "Show hidden files" parameter.
4. Click "Apply" and "OK".
After that, hidden files will be displayed on the drive (as in other computer recording devices), among which the virus USB drive is also located. To get rid of such a virus, find the file "autorun.inf" on the flash drive (it must be hidden and displayed in the form of a translucent icon) and remove it.
After removing the virus, the USB flash drive is recommended to check the antivirus again when you connect to the computer.
Problems with a flash drive connection after updating or reinstalling Windows
This may occur due to system errors after the update, reinstall OS or incorrect operation of the USB driver.
In this case, it is recommended to check using the USB troubleshooting tool in Microsoft utility.
To download and launch this utility you will need:
1. Go to the utility page on the official website of Microsoft.
2. Click on the "Download" button.
3. Run the downloaded file ("winusb.diagcab").
4. Press "Next" and wait for the test results.
In case of troubleshooting, click "Next" and wait until the utility fix system errors associated with USB. Then restart the computer.
After checking, correcting errors and restart the operating system, the problem with reading flash drives will be solved.
File System File System Errors
Another reason for reading a flash drive error can be damage to the file system of the USB drive itself, then a message appears with the offer to formatting. Visually, such a problem can be defined if there is a diode on the flash drive: when the device is connected to the computer, it flashes very slowly. A similar problem occurs when the flash drive is incorrect from the computer, the voltage jump or incorrect attempt to flash it.
To make sure that the reason is this, it is enough to connect the drive to another computer. If and there it slowly flashes, or the notification pops up, then you need to check the file system for errors. To do this, you can use Flash Drive Information Extractor:
1. Go to Flash Drive Information Extractor's official page on the Antspec Software website.
2. Click "Download usbdriveinfo.zip" at the top of the page.
3. Load the portable version of the utility.
4. Run the "getflashinfo.exe" file from the downloaded archive. After that, the program will show you the full information about the flash drive and its file system:
If there are FAT, FAT32, NTFS or EXT4 values in the File System string, the file system of the drive is proper. If this value is displayed as RAW, the flash drive needs correct formatting.
But before this you need to restore the data from the flash drive.
For this, the R.Saver program is well suited. The algorithm is the following:
1. Run the program and go to the flash drive (it will be in the "This Computer" section), then click the Scan button.
2. On the proposal of the program to start the sectoral scanning, answer "yes."
3. After the scan is completed, click the Mass Selection button and check the files and folders to be restored.
4. Specify the folder to save data from the flash drive and click the "Select" button.
After that, the data from the flash drives will be restored on the computer in the folder you selected. The USB drive itself, respectively, can be formatted by standard Windows tools, and reconstructed the restored information to it.
Physical damage flash drive
It is not necessary to exclude a physical malfunction of a USB drive if it is refused to "read" on the computer.
This can occur as a result of its fall, entering the moisture or dust inward. Most often, such flash drives become faulty. In this case, it is recommended to contact a specialized service center.
What to do that the flash drive served longer
To increase your USB drive's life cycle, you should follow a few simple rules:
- Do not connect a flash drive to a computer while starting the operating system;
- Do not remove a flash drive from the computer during direct work with files stored on it;
- Conduct preventive work with flash drives, including its defragmentation.
If the flash drive is faulty at the program level, most often it can be restored (including data stored on it). But if the drive has physical damage, unfortunately, have to accept the data loss. Therefore, do not forget to make backup copies of very important documents and files.
Periodically, we need to transfer data from a computer to an external drive or, on the contrary, consider information from it. But what if the computer does not recognize the drive? We understand this material.
Check ports and drives
The reasons why PC does not see the drive, there may be weight. To narrow the search, the first thing you need to check the drive on another device, and to try other drives to use the USB port to be used. If the flash drive is visible on another device, the problem lies in a USB port or software. The standard connection of the drive to the computer is accompanied by a beep and activation of the LED. If you insert a flash drive, and it does not respond, then this is a reason for anxiety.
In this case, it is worth checking the drive on the signs of mechanical damage to the chip and contacts, as well as water from entering the drive. In case of serious damage, the output is only one - service center, but the repair may cost disproportionally and makes sense if you need to extract very valuable data. If there is no important documents on the flash drive, it is easier to just buy a new one.
Problems with USB ports
Front USB ports of the computer are very convenient when we need to quickly connect the drive - you do not need to reach back to the back of the case and search for the desired connector. But often they are the cause of the "invisibility" of the drive. The front panel of the USB ports of the PC could trite forget to connect when assembling a computer. Check it is quite simple: remove the side cover of the case and find the corresponding wire that goes from the panel. As a rule, this is the most massive wire in the bundle.
If several USB ports do not see a worker drive, then the problem may hide in the BIOS. For some reasons, USB ports can be disabled. To enable them, you need to find the corresponding point in the menu, as a rule, this is "USB Configuration", depending on the manufacturer of the motherboard and in the "USB Controller" line, specify the "Enabled" value, then save the settings.
Another common problem is to pollute ports. We often wear a flash drive with you in your pocket or as a key chain, and PC connectors in turn are constantly open. Dust and dirt accumulates on contacts, in connection with this, the drive is not determined by the device from the first time. Therefore, you should not neglect the cleaning of the connectors and perform it periodically.
Lack of nutrition and use of splitters
In some cases, the USB port is simply lacking food, which does not see the connected drive. If in the system an old or low-power supply unit, and the PC consumption grows, then the required current level does not reach ports. A large number of USB ports involved can also cause this. To use the drive, you may need to disable multiple devices.
The problem may be in the USB splitter used - a defective USB hub or a lack of its power. The exit will be the use of a splitter with separate power. Next, consider the program reasons associated with the OS.
Often, when connecting a new drive, OS issues a warning about the need for formatting. This operation must be carried out to avoid various conflicts of file systems - an obviously good flash drive may not be displayed in the conductor. A serviceable device should appear in the device manager. To check this, proceed by "this computer-> Properties-> Device Manager". In the "Disk Devices" tab, we will find our drive.
Warning About the need for formatting may appear even if it is not the first flash drive connection. But all the data on the drive is deleted with formatting. If valuable information remains on the flash drive, the formatting should be performed using a "fast" method, that is, cleaning the table of contents. In the future, you can restore the data using specialized programs.
To format the device, select the appropriate drive in the "Computer" tab, click on the right mouse button and select "Format". In the window that opens, put a tick opposite the "Fast" item and select the file system, as a rule, it is NTFS.
If you do not specify this formatting method, the information on the drive will be completely erased, without the possibility of recovery.
Incorrect drivers and viruses
Systems in the system and outdated drivers often lead to incorrect drive of the drive. To verify the device, you will need to go to the device manager, discussed before the method. Incorrectly recognized drive will be designated as an "unknown device" icon with a yellow exclamation mark or in the "Other Devices" section. In such a situation, you need to click on this device with the right mouse button and remove it.
Next, select the "Action-> Update Equipment Configuration". After these operations, the drive must appear in Windows Explorer.
If this solution did not help, you can use the removal of drivers for USB controllers. To do this, go to the USB Controllers tab and to remove the "USB storage device" previously discussed, and then click "Update Equipment Configuration".
Another reason is viruses. Loading files from unsafe sites and connecting the drive to infected computers can lead to the inability to the device. The exit will be the use of antivirus software. Using it, you can fully scan the PC and the drive, after which it is possible to remove unwanted viral files.
Problems with sections and conflict addresses
When you connect the OS flash drive, it may incorrectly determine it, as it is assigned a letter that has already been occupied by another drive or has not yet been assigned at all. In this regard, it is not possible to open the drive, although it is displayed in the conductor. The decision will be a manual task of a specific letter to the drive. To do this, go through "Start-> click right-click-> Disk Management" and select the desired drive. I click on it with the right mouse button and select the "Change the drive letter or the path to the disk" item. It remains to ask any letter from the list with the condition that it does not coincide with the letters already used by other drives.
Unattophered file storage storage can also lead to the inoperability of the device. You can fix it in the "Disk Management" tab.
By clicking the right mouse button on the unallocated area and in the menu that opens, select "Create a simple volume". It is worth remembering that after this procedure, the data on the flash drive will be erased.
In the process of work, we may need utilities for diagnosing the state of the storage. Consider several popular solutions.
The CrystalDiskMark program familiar to many allows you to quickly get the speed of the drive, be it a flash drive or external HDD / SSD.
By installing the program, it is enough to select a test drive, the size of the recorded file in the test and the number of test launches. After the test is completed, information about the speed of read / write the drive will be displayed.
A simple chipeasy utility allows you to get complete information about the drive, which will not be superfluous if the marking with the characteristics was lost or was not at all.
After installing the application, it is enough to open it and select the desired drive. In the corresponding window, information about the manufacturer, the model of the controller, firmware and the file system will appear.
Almost the "omnivore" utility Flashnul diagnoses and corrects a variety of software errors. Reading, writing, writing and safety tests, sectoral record and checking the availability of each drive sector, this is not the entire list of features of this program.
By downloading the application, we get to the main window of the program, which will be familiar to those who previously worked with the command line. Operations are performed using pre-specified commands that can be studied in the file attached to the utility.
When you connect a flash drive to a computer, the user may encounter such a problem when a USB drive cannot be discussed, although it is normally determined by the system. Most often in such cases when trying to do this appears "Insert the disk into the drive ..." . Let's deal with what methods can be eliminated by the specified problem.

Ways to eliminate the problem
The choice of the direct method of eliminating the problem depends on the root cause of its occurrence. Most often, this is due to the fact that the controller works properly (therefore the drive is determined by the computer), but there are problems in operation of the flash memory directly. The main factors may be the following:
- Physical damage to the drive;
- Violation in the structure of the file system;
- Lack of sections markup.
In the first case, it is best to contact a specialist if the information stored on the flash drive is important for you. On the elimination of problems caused by two other reasons, we will talk below.
Method 1: Low-level formatting
The simplest way to solve the specified problem is to format a flash drive. But, unfortunately, the standard way to carry out the procedure does not always help. Moreover, with the problem described by us, it does not even start it in all cases. Then it will be necessary to produce a low-level formatting operation, which is made by using special software. One of the most popular utilities for the implementation of the specified procedure is the Format Tool, on the example of which we will consider the actions algorithm.
Attention! It is necessary to understand that when launching low-level formatting operation, the entire information stored on the flash drive will be irretrievably lost.
Download HDD Low Level Format Tool
- Run the utility. If you use its free version (and in most cases it is quite enough), click on "Continue for FREE" .
- In a new window, where the list of disk drives connected to the PC will be displayed, highlight the name of the problem flash drive and click "Continue" .
- In the displayed window, move to the section "LOW-LEVEL FORMAT" .
- Now click on the button "Format This Device" .
- The following dialog box displays a warning about the danger of this operation. But since the USB carrier is so faulty, you can safely harm "Yes" Thereby confirming the launch of the low-level formatting process.
- The low-level formatting operation of the USB drive will be launched, over the dynamics of which can be monitored using a graphic indicator, as well as a percentage informer. In addition, information will be displayed on the number of processed sectors and the speed of the process in MB / s. If you use the free version of the utility, this procedure in the processing of the volume carrier may take a fairly long time.
- The operation will be fully completed when the indicator will show 100%. After that, close the Utility window. Now you can check the performance of the USB carrier.
Lesson: low-level flash drive formatting
Method 2: "Disk Management"
Now find out what to do if there are no partition markup on the flash drive. Immediately, it should be noted that in this case it will not be possible to restore data, but will only reanimate the device itself. Correct the situation by applying a standard system tool called "Disk management" . We will consider the actions algorithm on the example of Windows 7, but in general it is quite suitable for all other OS WINDOVS line.
- Connect a problem USB carrier to a PC and open the tool "Disk management" .
Lesson: Disk Management Function in Windows 8, Windows 7
- In the window of the opened snap, find the name of the disk corresponding to the problem flash drive. If you have difficulty in determining the necessary media, you can navigate the data on its volume to be displayed in the snap window. Please note if the status is right on the right "Not distributed" This is the cause of the USB drive fault. Clear the right mouse button on the unattown location and select "Create a simple volume ..." .
- The window will appear "Masters" in which click "Further" .
- Note that the number in the field "Size of a simple volume" It was equal to the value opposite the parameter "Maximum Size" . If it is not true, actualize the data according to the requirements described above and click "Further" .
- In the next window, check that the radio channel stood in position. "Assign a disk letter" From the drop-down list opposite this parameter, select the character that will be configured to be created and displayed in file managers. Although you can leave the letter that is assigned by default. After executing all actions, click "Further" .
- Put the radio button to the position "Format…" and from the drop-down list opposite the parameter "File system" Select option "FAT32" . Opposite the parameter "Cluster size" Select Value "Default" . In field "Tom Mark" Push the arbitrary name under which the flash drive will be displayed after restoring the performance. Install the checkbox in Chekbox "Fast formatting" and press "Further" .
- Now in a new window you need to click "Ready" .
- After these actions, the name of the volume will appear in the snap "Disk management" , and the flash drive will return its performance.
Do not despair if you stopped opening a flash drive, despite the fact that it is determined by the system. To correct the situation, you can try to use the built-in tool. "Disk management" To create a volume, or make low-level formatting, applying a special utility for this. It is better to produce actions in such a sequence, but not vice versa.We are glad that you could help you solve the problem.
