The flash drive flashes but does not open. Why does the computer sees a flash drive or an outdoor hard drive and what to do about it

Sometimes at the most inopportune moment when it urgently needs to throw out information from a flash drive on a PC, the computer refuses see a new device. Between O. causes of occurrence We will try to tell this problem in our article in detail in our article.

Hardware fault

So if your the computer does not seeUSBflash driveThe first thing when the problem is detected should check the serviceability of the flash drive and the USB connector. A properly flashing light indicator will flash in a properly operating device in a working port. If the indicator flashes, and the computer does not recognize the flash drive anyway, then the problem is to search in the operating system.

Disadvantage

Frequently, the flash drive does not function when connecting to the port, which is located on front panel block. It happens that such connectors simply do not connect to the main power supply, and sometimes there is an insufficient nutrition. In this situation, you must try to connect the device to the free port on the back of the computer.

Flash drive may not work With a lack of power supply. This happens when there is excessive current overload in USB ports or a USB hub, as well as with faulty functioning of the power supply. In addition, it happens that the computer does not see the flash drive because it is too large, but as a rule it is rare.

Fault flash drive

If after performing all previous actions, the computer is still does not see a flash driveThen the reason may be in the device itself. Take a try connect it to another computer. If USB memory does not function on other PCs, then you can confidently say that it is faulty. It should be attributed to the diagnostics to a competent specialist.

Repair a flash drive is possibleHowever, very often repairs cost more costs. Therefore, it is necessary to repair the device at a strong need. In other cases, buy a new drive cheaper.

BIOS settings

The problem is sometimes hiding in the settings of the operating system. For example, the computer does not recognize the flash driveIf USB support is activated via BIOS. When the configuration in the BIOS is executed, a message may appear with the inscription " USB device is not recognized" This may be due to the following reasons.

Flashke is automatically assigned a busy letter

A very common problem is when the system assigns the device already occupied by the driver of the connected disk. To eliminate malfunctions in this way:

It happens that computer does not see a USB flash drivebecause there are no or outdated necessary. In this case, the update of the motherboard drivers will help. The name of its model can be viewed through the Everest program. Drivers follow download from the official website of the developer.

No USB Driver

Sometimes there is no special driver on the computer and it is for this reason. the computer does not see a flash drive Wherever we did not insert it. Check out such a gueside in this way:

1. Go through Control Panel on the menu Device Manager;
2. In the proposed list of devices it is necessary to find USB controllers. One or more USB devices, in the absence of a driver, will shine with a yellow question icon;
3. You should remove the incorrectly working device and set it again.

Viruses in the system

Sometimes the viruses in the operating system affect the correct functioning of the flash drive. In this case, you need to scan the computer with an antivirus program and.

File system incompatibility

Another reason why the computer does not see the flash drive can be the fact that the computer does not work read the file system. It most often occurs when the file is installed on the flash drive fAT system. You need to try to perform device devices NTFS or FAT32..

As you can see, the incorrect work of the flash drive can be caused by the problems of hardware or software. That is why in each case it is necessary to sort out different reasons.

Over the past few years, flash information carriers have become very popular and used by us, literally, daily, thanks to their advantages over disk carriers. It is unlikely that you can overestimate its benefit of the media flash, because you can quickly write information to it or count, does not take much place in the portfolio or bag, and the price segment is pleasantly happy.

Despite all the positive moments, sometimes there are situations when reading the data does not work because of the flash drive itself or computer. After all, at the most important point you can lose access to stored files, and to quickly return everything to normal, you must have certain knowledge. In this article we will analyze all possible problem situations and find ways to solve why the computer does not see the flash drive.

The most common problems why the computer does not see a flash drive:

Flash drive itself

This is the worst alignment for a person whose documents are stored on the flash drive, because it is almost not realistic to return it to life. You can deal with the flash drive with a mechanical effect on the device chip or its controller, closing the electrical circuit, damage to the contacts on the USB board. This looks like a flash drive after closing the electrical circuit or moisture getting inside the drive.

To determine whether it happened with your drive easy enough. The very first, then you need to do - check the flash drive for mechanical damage, cracks, etc. If it is completely broken - you can look for a replacement in a computer peripheral store. If you doubt its inoperability, you can check it with a practical method.

Connect the flash drive to the USB connector of the computer if the LED on it caught fire and on the computer you heard the sound that is characteristic of connecting a new device, it means everything is in order, it makes sense to look for a problem further. If this did not happen - most likely the flash drive is no longer suitable for operation.

You can try to attribute a flash drive to a service center, where the wizard will try to turn off contacts or replace the controller, but it will be very expensive, but it will justify this action only if you have important documents on it. If the fatal malfunction was not detected and the flash drive submits signs of life Try methods for restoring its performance, which will be described below.

On the front panel of the computer de-energized USB port

This problem is very common among desktop users. Most computer owners are used to inserting a USB flash drive in front ports, because it is quick and convenient.

But the situation occurs when during the assembly of the PC for some reason does not connect the front panel to the power system, it usually occurs on the forgetfulness of the computer master. Accordingly, your flash drive will not be displayed, despite its complete service.

This problem can be solved in two ways. If you urgently need to use information on removable media, you can connect it to the back of the computer. Front connectors will remain all non-working, but you will get access to documents. Name such manipulations are not a full solution, so consider the second option.

Method number 2 implies the connection of the energy skill on the motherboard to the front panel of the computer. Depending on the computer case, the connection connectors may differ. But you should not be afraid of them all have labeling and connect not that connector you will not be released by structural features. The most common wires of the types "VCC", "D-", "D +" as well as "GND". Moreover, the color marking of the cable and the connector on the motherboard coincide, but it is better to keep the benchmark for inscriptions.

First of all, you need to access the motherboard, to do this, unscrew the fastening bolts on the housing and remove the lid. Find the cable that leads to the front panel and find the same connector on the motherboard. In the image below you can see how the connector should look like.

It is not recommended to perform the connection on your own, it is better to call the wizard. If you incorrectly connect the cable and the connector, you can burn these contacts and even devices. If you decide to connect front USB connectors, then better inform us the model of your case and the motherboard, and we will tell you how to do it correctly and explain what the connector and cable looks like.

Faulty or disabled USB port on a computer

Sometimes the problem of the non-definition of information on removable media is not associated with the problem of the flash drive itself, but with the connector in which it is connected. A specific USB port can be not working, and such a state can be caused by banal damage to the connector contacts. Then this port will not work not only flash drive, but also other USB devices.

You can solve this problem, armed with a conventional soldering iron and minimal knowledge of circuitry. If there is no knowledge, skill and equipment - then it can be fixed in the nearest service center for a low fee.

However, if no response to the USB connection device is observed on all connectors, then the problem can be deeper. Ports can be disabled in BIOS settings.

In order to connect the ports in the BIOS menu, you need to get there initially. To enter the BIOS in the first seconds of the computer loading, you need to press the corresponding key on the keyboard, which is responsible for calling the menu. Most often, the default key F2 or DEL is set, but depending on the company of the motherboard and the bios version, it can be different. In the first image that pops up when loading it is indicated.

After you entered the BIOS itself, we need to go through the following route: "".

Find the "USB Controller" line so that you are allowed to use ports, on the contrary, it must be "enabled".

After you have turned on USB ports on your computer, press the F10 key. It will save the settings you set and will come out of the BIOS.

Polluted USB flash drive connector

The flash drive is a mobile storage device and therefore often worn in pockets, briefcases or as a key chain on the keys. Due to such operating conditions, dust can accumulate in the connector, small garbage. This happens not often, but it may cause an inoperability of the flash drive. Dust and fine garbage is collected by a touch on the contact and does not allow connecting to the ports to the port on the computer. Such a flash drive can not only be displayed at all, but also hang, slowly transmit or read information and determined from the first time.

To clear the USB flash drive connector arma your match and cotton wand. A flying machine, remove the entire garbage from the connector, and then moisten a cotton wand with alcohol and wipe the contacts of the flash drive. So you get rid of her garbage and oxidation.

Infecting viruses

Nowadays, the security of drives of drives is becoming more urgent, because viruses are fully operated. You can visit your usual social network site on the Internet and get infection, not to mention the download of files from unverified sources.

Modern computer viruses can also multiply, no matter how strange it sounds. They infect files that are on your flash drive or hard disk of the computer, and their number is growing in exponential addiction.

Very often the problem of the disability of the flash drive is infected with viruses. The drive is determined by the system, you can hear the characteristic sound of the device connection to the system, but when you try to read the information, you will see a message "" or " The application is not found».

Before solving this problem, you should install anti-virus software on your computer and perform full file diagnostics. To access data on the drive, we need to delete a file with a virus and scan it. To do this, go to the "Start" menu and enter the following phrase "" in the search stitch.

On the found item, press the left mouse button. You will be an open window with the name "folder parameters", here you need to do the following:

• Remove the tick from the parameter " Hide secure system files»
• Put a tick on the "" parameter

After that, we definitely press the "Apply" key and only after that "OK", otherwise the changes will not take effect. It should look like this.

After that, go to "My Computer" and go to the folder of the drive itself. There you will see the "Autorun" file, it must be removed, and the flash drive to check for viruses is one of the free antiviruses, the Dr.Web Cure IT utility is perfectly cope with it.

Now you can fully use the flash drive and there should be no problems. If nothing has changed, it means the problem is the absence of drivers, we will analyze it below.

Driver failure or use of outdated drivers

The problem is very common when the computer does not want to display a flash drive due to obsolete drivers or their system failure. A failure can pass due to the electrical voltage jump or unforeseen completion of the operating system. Or old computers can not work with 32 GB and more. You can say one thing, the problem is solved only by updating drivers.

First of all, you need to go to "". You can do this in several ways, for example, through "My Computer" or find this section in the system search, as we will do.

We go into this menu, after which you connect the flash drive to the computer, after which you open the "USB controllers" sample. We highlight the string " Memory device", I click the right key of the mouse opens the system menu and click" Delete ".

Such manipulations allow you to delete the driver installed in the system for your storage device. As soon as you delete it, feel free to get a flash drive from the computer and connect it again. Then the driver on the flash drive will be reappeared and the problem will be solved.

If the problem has not been solved, it is possible to update the driver of all USB chipsets, to do it quite easily. You can use a special disk that walked with the motherboard, all the necessary drivers are recorded on it. If you do not have it, download the DriverPack program, it will automatically allocate all the drivers for which there is an update and holds this procedure after your agreement.

Moreover, most users have doubts about the correctness of their actions when they find out about different USB formats. Do not be afraid!

Drivers on USB 2.0 and USB 3.0 are installed in the same principle. And the only difference between the ports is the maximum read speed and write information.

File System Errors

The computer may also not define your flash device due to file system errors. Check if it is, go to "", how to do it was described above. Now you need to open the subject " Disk devices"If you see your flash drive there, it means it is good, and the file system does not perceive it as it should, and, accordingly, does not displays in the conductor. In my case, the flash drive appears, it means it is working.

To correct this problem, you must format your USB flash drive, but this action has several nuances, so consider this process in the next paragraph of the article.

If you do not see your drive there, then the problem lies in the malfunction of the flash drive itself, it means that the controller burned down, or the contact dropped. Try to return her to life can specialists in service centers. However, this is an expensive lesson, it is easier to buy a new one, of course if important information was not recorded on the faulty and you need to restore the data on the flash drive.

File System Conflict

Quite often, the contents of the flash drive is not displayed due to the conflict of file systems on the computer and the most removable media. For example, if the computer functions on the NTFS file system, FAT32 is used on the flash drive, the conflict situation is not excluded. Moreover, this problem is distributed not only in the Windows environment, but also Mac OS. For example, if you format the USB flash drive on your MAC device to the EXFAT system or the standard Macbook file system, the flash drive is unlikely to be read on Windows devices.

The very first thing to do is to find a computer where another file system is used, open a USB flash drive and save the importance information for you, because after formatting it will be lost.

To solve this problem, we need to carry out the process of formatting a flash drive. First you need to find out which file system is used on your computer. Go to My Computer, the right click of the hard disk mouse over the submenu and select the item "Properties" in it.

In the window that opens, you will see information about the free and busy amount of disk space, and also learn what file system is used. In my case, the NTFS system is used.

After you learned the computer file system, we need to format the flash drive into the same system. To do this, click on the flash drive with the right mouse button and open the Format tab.

In the tab that opens, select the file system into which we will format, put the box opposite the "fast" attribute and click "Start".

A few words about why we use the rapid attribute. First, formatting a flash drive will occur much faster. But there is another side of the medal. If there were some documents on the flash drive, then only with quick formatting you can restore this data using special utilities. If you did not put a tick, then the information that was on the flash drive will be lost forever.

The flash drive is not formatted

A problem is quite common when you insert a flash drive into a computer (basically this is a new flash drive and its first use), and the operating system gives you a warning that says that before using, a removable disk must be formatted. And if the flash drive was previously used and data recorded on it, then access to them will not work. Moreover, the volume of the flash drive becomes equal to 0, i.e. As if there is nothing there, even the drive.

If you have already enjoyed a flash drive and it is not the first connection, then try to connect it to another computer, it may take a problem, and you can save data. But in any case, the flash drive is subject to formatting. How to do this, it was disassembled in detail in the "File Systems Conflict" item.

But I want to draw your attention for two points. So that after formatting there are no problems with the file system (FS), find out which FS is used on the computer and install the same for the drive. And the second, if the information you need on the flash drive, be sure to use the "Fast" attribute, so formatting the flash drive will be only on tables, and the lost information can be returned using special utilities.

The problem with the section or flash drive is automatically assigned a busy letter

There are situations where the operating system incorrectly defines your removable media. It seems that everything is fine, the connection of the device is displayed and the flash drive icon appears in the tray, and it is not possible to use it by destination.

The problem may conclude that the system did not assign the letter under which the removable drive will appear or assigned, but this letter is already busy, and because of this, addresses conflict is obtained.

The solution to this problem will be forced assigning the letter of the section that we choose, everything happens in manual mode. So, proceed.

First of all, it is necessary to hold the combination of the "Win + R" keys, the window opens with the name "Run".

In the line we need to enter a simple command diskmgmt.mSC. which will transfer us to the disk management and drives section.

In the accumulative media manager that opens, we need to define our USB device. You can simply do this, turn off the USB flash drive and connect again, the partition that will first disappear and then appear, we need.

In my case, the flash drive is the drive with the name "20151114_17", you can also determine it by a special icon. Now you need to click on it with the right mouse button, and in the menu that opens, select "Change the letter".

Now we will open another additional window, smaller. It is necessary to click on the "Edit" and "OK" button.

Now another auxiliary window will open, where you must choose any letter of the English alphabet, and after clicking on the "OK" button, the letter will be assigned.

It is worth paying attention to one important point! When choosing a given letter, section your flash drive, see what letters are already used by the system. This is very important, because we can not correct the problem, but leave it. This will happen if you are, for example, the section of the flash drives indicate, through the letter "D", which is already assigned to the local disk.

Power supply faults or excessive overload of a USB portal current

This problem is very common in our time. The fact is that the computer can simply not see the flash drive due to the malfunction of the power supply. We'll figure it out in order, the power supply consumes electrical energy from the network, and after it converts and distributes it across all nodes of the computer. It has limit power, for example, a 400W power supply unit, will not be able to give you 600W. And it means that the entire system consumption must be balanced.

Such a problem may appear if you recently replaced some important node in the system, let it be a processor. Now he consumes much more energy, in comparison with the past, which means somewhere it simply does not reach, and in this case it "somewhere" is a USB network of a computer. Accordingly, the power consumption parameter must be calculated in advance, and if such a situation has already occurred, you will have to replace BP to more powerful.

Moreover, the problem may be in the malfunction of the power supply, it can produce much less power potential than declared, and what he gave before. You can't solve such a problem, since you risk the performance of the entire computer. The only solution will be the replacement of the power supply.

There is another feature of this issue. Recently, a USB device for computers has been very common, allowed such devices now: a cup for heating a cup, a table lamp, a wireless mouse, a removable hard disk, and in the addition of the smartphone also stands on charging. And you want to connect another flash drive, but it seems that the computer sees it. The fact is that the current overload on USB ports has occurred. Those. All your devices already consume the maximum number of current and one more you cannot connect. Therefore, in order to use the flash drive, you need to turn off a multiple device from USB port ports and then the problem will disappear.

If the computer does not see the USB flash drive in Windows XP

It has a set of reasons for which the flash drive may not be determined in the Windows XP system. Moreover, the problem may be walking both in the operating system itself and in flush faults, and even in the hardware of the computer.

If the problem is related to the operating system, it is possible to eliminate it only by making additional changes in the settings, to do it best in manual mode, despite the abundance of special utilities that can help in this matter.

However, if the drive itself is faulty, the only thing that remains for you is to try to save the data recorded on it. And then purchase a new and more reliable device.

If your computer cannot define a flash drive, then it notifies the user with the following signals:

• Your flash drive is inserted, and you are trying to access the data on it, the message "Insert the disk" message pops up.
• The system notifies the mandatory formatting of the drive for further use.
• Errors about the impossibility of accessing data pops up.
• The system may freeze as soon as you connect a USB flash drive in the computer's USB port.

In this section, we will consider all the most common causes of the not functionality of the flash drive in the Windows XP system and give practical recommendations for their solution. Carefully read the description of the problem if it does not look like your or her decision did not help you, go to the next item until the problem leaves. First, then you need to do, it is trying to determine if the flash drive is working. This is alarms the light indicator located on it. If you have connected the drive, and it flashes or burns, then the flash drive is properly and the problem lies either in the system or hardware of the computer.

Try to change the port in which you connect a USB flash drive or even a computer may only be faulty port or the entire system, and on another PC flash drive will work correctly. For example, if when you connect a flash drive to port, you observe the full system hanging, then this means this port is defective and it is better not to use it.

If you are using USB hubs or extension cords and the flash drive is not displayed, it is possible that the problem is linked in the device itself, not a flash drive. If it turned out, you can attribute a hub into a service center or try to repair it yourself. To do this, you will need a soldering iron, solder and some experience, because most often you just need to solder one or two contacts and everything will work as it should be.

Perhaps the problem lies in the disadvantage of the electric current in the USB ports. What would you check, you need to disable all USB devices on your computer (camera, printer, lamp, etc.), leave only the keyboard and mouse. If after such manipulations, the flash drive will be displayed in the system and you can access it, then the problem lies in a weak power supply. You can solve this problem only to replace the power supply to more powerful, but to delay the purchase of BP will help using a USB hub with its own energy source.

However, if the problem did not decide after disconnecting all other devices, everything can still be a relevant problem with the disadvantage of the power supply power and outdated USB port. In other words, on old laptops you will not be able to open a flash drive of 36 GB and more. There will not be able to solve the problem, you can only buy a more modern laptop or computer.

Very often there is a situation where the user connects a flash drive to the front port of the PC, and the system does not see it. This means that any ports are not connected to the power supply unit on the motherboard, or too little power is distinguished. You can connect the front panel yourself using the manual located above in the section of the same name.

Does not see a flash drive due to Windows XP errors. Elimination of problems

The flash drive may also not be determined due to the operating system errors. For example, Windows XP SP2 does not have updates and software packages that provide normal USB devices. Moreover, a situation is possible when only several USB devices can work in one port.

The solution to this issue will be updated the system to SP3 and install the necessary updates. Make it can even be a new user, since it takes only a couple of clicks, and the system will automatically download, install and run the update. So, proceed, we can move in two ways - this is the official download from Windows Update or install SP3 from a disk or flash drive. First of all, you need to check which package you already installed.

Click the My Computer icon with the right mouse button and select "Properties". You will appear in front of you, where information about your system will be specified.

To install SP3, we need to allow the operating system to search and update the computer system. To do this, it is enough to go from the control panel in Windows Update.

As soon as you do this, the system will start searching for updates, after which it will offer you to update everything at once or choose only you need. If you do not understand how to update, what changes, then it is better to update the system completely.

After downloading all updates, the operating system will require you to restart the computer to apply new settings. Click "OK" and is waiting patiently. That's all, you can now connect the USB flash drive and use it.

If you decide to select updates to be installed, and not upload them all in automatic mode, then here is a reference point that will help improve the perception of USB drives by the system.

Driver Conflicts in Windows XP

There is also the problem of the conflict of drivers. The fact is that some of the obsolete drivers can cause errors at the system level, moreover, they may interfere with the normal operation of new drivers. A vivid example of such a problem is the situation when the user inserts a flash drive into the computer, trying to access the data on it, and the system immediately knocks the error message asking you to insert the disk. Or, the system simply hangs, and even assigning an existing letter to the flash drive actually.

The reason for such errors is as follows. Suppose you have two flash drives, you connected one of them to the system. In automatic mode, all the necessary drivers are immediately installed for this device. You made the necessary manipulations on recording or reading files and pulled out the drive. After that, you insert the second flash drive, which is fully working, and pops up one of the above errors. This means that the system is trying to use the already installed driver from the first flash drive to start the second, and they are not compatible.

Reinstall Windows XP drivers for USB devices

This problem can be easily eliminated in several ways. Reinstalling drivers in automatic mode or manual. We will analyze a bit of theory, the driver from one USB device can be mistakenly used by the system to start another USB device. To exclude these problems, we first need to delete all the available drivers for USB drives, and then re-install them.

Such a problem may issue a "USB device is not identical" message, or the inexplicable processes occur at the system level, which close data access or cause system freezing.

Remove through DriveCleanup.

You can effectively delete all available drivers for USB devices using the DriveCleanUp utility. Its advantage is that it produces a search throughout the system for the presence of installed drivers and only after that removes them.

First of all, turn off the computer, turn off all USB devices from it, in order to avoid conflict situations while running the program. Turn on the PC, go to the official website of the program and download the executing file. The utility is compatible with any versions of Windows, including different trimming. When loading, pay attention to the version of the file.

Automatic installation

You deleted all drivers from your computer. To function normally function, the driver must be present in the operating system. The process of automatic installation The driver is incredibly easy, you just need to connect a USB port in USB, then the installation will immediately begin. The window will pop up, which will display the installation progress, on some systems it can occur in an invisible mode. For one or two minutes, the installation will be completed, and you can use the device.

Manual installation

Under manual installation, the installation of drivers is not directly from the carrier of the information. We can also install drivers for a flash drive from third-party resources, but to avoid conflict situations, we will make the installation of drivers for a flash drive using another computer.

So, we take our problem flash drive, insert into another computer, where it is recognized. Be sure the condition of this process is the coincidence of Windows versions on both computers. We use searches on the system and find two files.

By any means we pass them on a problem computer, be it sending by mail or the use of another removable media. Put these files need to be in the folder with the same path that was on the first computer and confirm the replacement when the corresponding window is popped up. Reboot your computer and enjoy it with work with Flash discs.

We only reviewed the most common reasons why the flash drive is not displayed on the computer. In fact, there are much more. Moreover, there are problems that are expressed by other system messages, and their solution is already described in the paragraphs of the article.

The appearance of the message "Insert the disk", even if the flash drive is already connected to the USB port

This system error occurs to be if the drivers are superimposed on each other and impede the normal functioning of USB devices. In order to correct this error, you must delete all the drivers for USB devices and set them again. This process is described in stages in this article.

Message about the need for disk formatting

Such a message appears in the event that you first use the USB flash drive or a system failure occurred in it. In addition to the message, you can make sure that it is not suitable for use, because it does not displays any free space, nor occupied. The decision of this issue is described in detail in paragraphs 8 and 9.

Data error message

This problem pops up in 3 cases. This is a conflict of drivers, conflict of file systems and faction failed. It is solved by reinstalling drivers, if it did not help - then quick formatting to keep the ability to restore data on the flash drive. Step-by-step instructions are above.

Full system freezing immediately after connecting a flash drive to a computer

This issue has already been seen in the article, but I would like to pay attention to that this error may occur for two reasons:

1. Conflict drivers.
2. Faulty port.

Check what kind of problem you can easily insert a flash drive to another port if the hanging is repeated - then the problem with the drivers. The instructions and advice on their reinstallation were given within this article.

Why does the computer sees the flash drive when the indicator on it glows

Perhaps damage to the contact on the flash drive, which is responsible for the transmission of information. The conflict of the drivers and the appointment of a busy letter for the section is not excluded. If the problem does not leave, after connecting the flash drive to another computer, try checking the availability of the partition. If everything is in order, then reinstall the drivers and the flash drive will earn.

Error 43 / Error 43

This error immediately stops reading information from a removable device, which means access to data immediately get from us will not work. There are several problems that are able to call ERROR 43.

• The malfunction of the device itself is the first of them. Check that this situation will not happen on another computer.
• Drivers conflict - the solution is described above.
• Updating equipment configuration - just just roll back the driver in the task manager.

conclusions

We got acquainted in detail with the reasons that may prevent reading flash drives and information on it with a computer. The described decisions with step-by-step instructions will surely help you get rid of this problem. The non-definition of the flash drive can become a sentence only if the flash drive is faulty. In other situations, this is an easily reversible process. If you have any questions or you could not find a solution to your problem in the article - leave comments, try to clarify the situation together.

Hi friends! In this article you will know why the computer does not see a flash drive and what to do in such a situation. Today I will tell you how to cope with the common problem when the computer stops seeing the USB flash drive and does not display the contents.

We also consider the option when the laptop does not see the flash drive after formatting. Go? I ask everyone in advance to put like an article in order to help me in the development of this blog. Thank you!

The computer does not see a flash drive - what to do?

We have already talked about. But what can be done if the computer does not see a flash drive? We tried to collect solutions that are really useful and will help in solving this issue for you. If you have any additional questions - be sure to talk about them in the comments.

Causes of breakdowns

To begin with, consider the reasons for the problem described, because, as you know, there is no smoke without fire. In our case, these reasons may be a lot, therefore it is worth paying attention to the most important.

Often, on a personal computer, turn off the front panel, considering it not necessary. And as a result, we get a number of non-working USB ports.

Not working flash drive. Everything in our world has a bodging property. For example, flushes are often brazed due to improper use or long life.

In the yard of the 21st century, the century of high technologies, without viruses, just nowhere. Transferring infected files from another PC, it can be fraught with the following things: In the first case, the flash drive itself will not be visible to the computer, and in the second, you will not see files on the drive. Of course, your car can be an infected device, so I advise you to check everything for viruses.

Violation of Drivers. This does not often happen, but still happens.

The computer may not see a flash drive for a variety of reasons. In this article, let's try to deal with the main ones.

And so ... we went.

1. Disability of the device

First, check the performance of the flash drive itself. If one computer does not see her, try to insert it into another PC - if it works on it, you can move to item 2. By the way, pay attention to the LED (it is on many flash drives). If it does not burn - this may indicate that the flash drive burned down and became unusable.

2. Disability of USB ports

Try to insert into the USB to which you connect the USB flash drive, another device and see if it works correctly. You can take another flash drive, printer, scanner, phone, etc. You can also try to insert a flash drive into another connector.

On the system unit, in addition to the front panel, the USB connectors are on the rear wall. Try connecting the device to them.

3. Viruses / Antiviruses

Often the cause of invisibility of the flash drive can be viruses. You can also close access to the flash drive if there will be a potential danger to the computer. With a certain risk share, you can try to disconnect the antivirus and insert the flash drive.

In principle, if auto-launch is turned off (this option is turned off B) and you will not run anything from the flash drives - then no viruses on such a carrier should infect PC. If after turning off the antiviruses, the flash drive has been displayed - copy the files you need and carefully check them with the anti-virus program before opening.

4. BIOS settings

It often happens that USB ports can be disabled in the BIOS settings. Do this for various reasons, but if the computer does not see a flash drive, then look at the BIOS is extremely preferably. By the way, in this case, not only a flash drive, but also the remaining media and devices read and will not be identified!

When you turn on the computer, press the F2 or DEL button (depending on the PC model) until you see the blue table with the settings (this is BIOS). Next you need to find the USB settings here (you will often simply be the inscription Configuration USB). Since the variants of the BIOS menu is a great set, unambiguously indicate the path is unlikely to turn out. In principle, even here everything is in English, but everything is intuitive.

In my case, you first needed to go to the tab Advanced. Next choose USB Configuration. .

After you change the settings, be sure to save them before rebooting the computer. From BIOS you can exit in two ways: with saving settings and without saving. In the menu on the right or below, the output buttons will be specified, select the one where there is an inscription Save and EXIT. .

5. Assigning the letter of the already identified device

A very often inserted flash drive in the USB connector is assigned the letter already existing disk in the Windows system. To correct this error, go to control Panel and open the tab administration .

Now in the left column you need to select the option disk management . Next in the central part you will see all the discs and media connected to the system. The flash drive will be marked like removable drive. Click on it right and click on the function replace the letter of the disk . Change on the letter that you did not have in the system before (go to my computer - And you immediately recognize what letters are already busy).

6. Outdated Drivers

Frequent cause of the invisibility of the flash drive is the lack of the desired driver in the system. If you have an old computer, then flash drives, more than in 32GB on such computers it is impossible to read. Although why use flash drives such size - it is not clear yet (their reliability is still far from excellence).

Basically, such a problem belongs to the old OS. For example, Windows 95/98 / ME simply do not see the NTFS file system, therefore the media on which this file system will not be read in such an OS. To fix this, you will need to download special programs or drivers to see such a flash drive.

8. Dirty USB input

It happens that, however, rarely. Due to the fact that the flash drive is often worn in pockets, as a key chain on the keys, etc. - dust and flare accumulate in its entrance. If it is not cleaned, over time, on some models, flash drives - it can cause their bad readability: not from the first time the flash drive will be determined, often hanging when working with it, etc.

Read, what to do if Windows does not display the connected device. How to return the performance to such a device if the reason is in it. A flash drive or any other USB drive must be automatically determined by the computer and displayed in the Explorer and the "Computer" folder after connecting to the USB port.

Diagnostics of the problem

The first thing to be done if the connected USB disk is not displayed in the Windows file manager, you must check the tool Disc management.

In order to open Disc management In Windows 8/10, right-click on the menu Start and select "Disk management". In Windows 7, press the Windows + R key combination to open the dialog box. "Run" and enter the command in it diskmgmt.msc..

Check the list of disks in the window Disc management And find a USB disk that is not defined. It should be displayed here, even in the case of its absence in the folder "This computer", and coincide in size. Sometimes it is defined as "Removable device"But not always.

If you do not see your disk or flash drive, even in drive control, then try to do the following:

• Turn on the disc if there is such a function. Some external hard drives have a separate power cord or turn on using a separate key, intended for this key.
• Connect the device to another USB port. Turn off the USB flash drive from the port USB and connect to another. Perhaps one of the USB ports of your computer has failed.
• Connect the device to a computer without a USB hub. If a flash drive is connected to a computer via an extension cord or a USB hub, try to turn it off from it and connect to a computer directly. Perhaps the reason is in the hub.
• Try another computer. Connect the USB flash drive to the USB port of another computer, and see if it is determined. If the device is also not determined by another computer, then most likely the problem is in it.

Solution to the problem

If problems described above do not touch your case, then your problem is most likely to be solved by one of the ways described below. Depending on what you found in Drive controlThere are variants of solutions that have arisen with the definition of external information carrier.

If Windows sees the disk, but cannot read it, it means that it does not support the file system. In this case, the operating system will propose to format the disc before its use. But do not rush to do it! It will destroy all your data.

If other computers see a USB flash drive, and yours is not

In the event that other computers define your USB disk, and yours is not, then the problem with the device drivers is most likely.

To check this, open the Device Manager and find items. Disk devices and USB controllers. Look, whether there are no devices in these sections marked with a yellow exclamation mark. If this device is there, click on it with the right mouse button and select Properties. The properties will indicate information about the error and the status of the drivers.

To correct the problem with the driver, right-click on the device, select Properties / Driver / Refresh.

Disc is visible in drive management

If the disc is visible in Drive controlBut it does not have the letters, it is for this reason that it may not be displayed in Windows Explorer. To start it to be displayed in the conductor, such a disk must be assigned a letter.

To do this, right-click on it and select "Change the letter of the disk or the path to the disk". If there is no such item in the pop-up menu, this may be due to the lack of or unsupported by the type of information media file system.

In the menu that opens, you will see that the disc is not appointed - assign it. To do this, select Add / / OK..

If the disc is visible in drive control, but it is not distributed

If the disc is visible in Drive controlBut it is not distributed, it means that it is not formatted. In order for such a disk to be operational, click on it with the right mouse button and select "Create a simple volume".

Select the maximum proposed partition size and assign the disk letter offered by the system. After that, the disk will be normally determined by the system and is ready to use.

If the disc is visible in drive control, but it cannot be formatted

If for some reason the disk fails to format, then to return its performance, it can be completely cleaned, then re-create a section.

Note. As a result of this manipulation, all this from the disk (as well as flash drives or memory cards) will be permanently removed. Therefore, fight in advance about their safety - scan the disk or flash drive using the Hetman Partition Recovery, and save your data at a convenient place.

To cleanse the disc Open Command line on behalf of the administrator and clean it using the DiskPart command - "Clean".
