Why flash drive does not appear on my computer: what to do?
Removable media is very convenient. Today, flash drives are available up to 64 GB. A handy device connects to the USB-connector of the computer and allows you to quickly save important files and text documents. However, sometimes users are faced with the fact that the flash drive is not displayed on the computer. What to do in this situation? With what problems of a similar kind can be connected?
It is worth considering that sometimes the computer stopsto see a removable media, even if before that there were no problems with it. In some situations, the PC does not display the contents of the folders, and sometimes even "does not see" that the device is connected. Once in this situation, each user asks himself a legitimate question: "Why does not a USB flash drive appear on my computer?" Some start to panic, worrying that all the stored data will now be lost. But do not despair prematurely. First you need to calmly deal with the causes of the problem. There can be several such.
Lack of power or trouble with the socket
Usually there are stationary system unitsjust a few ports for connecting USB-carriers. Some of them are located on the frontal part of the "sistemnik", and they quite often stop working correctly.
In this case, you should try to insert the USB flash drive into theconnector located on the back of the computer. If there are no corresponding ports there, then you need to check the headphone output, which is also usually located on the front of the system unit. If the soundtrack does not play, the problem is due to a mechanical malfunction of the connectors. Another explanation is that they were not originally connected to the PC motherboard. Developers very often make this mistake in the production of "system specialists".
In addition, if the computer does not see the USB flash drive throughUSB, this may indicate that too little power is supplied to the connector, because of which the media is constantly turned on and off. This is due to the mistakes of developers who do not always put the cables in the proper grooves as tightly as possible.
If the folder "My Computer" flash drive is notis displayed for these reasons, it will be difficult to cope with the problem on its own. It is much easier to contact the service center or return the faulty system unit to the seller.
If the problem is not related to a lack of power or incorrect operation of the connectors, it is worthwhile to consider other reasons for the non-working removable media.
Each flash drive is installed by defaultsoftware that should be automatically activated when the device is connected to a PC. However, Windows 7 does not always correctly install the driver. Hence the most common reason why My USB does not display a USB flash drive.
To resolve this problem, you must go to "Device Manager". There are two ways to do this:
- Click the right mouse button on the inscription "My Computer" and select the line "Properties". On the left in the opened window there will be a list of available directories. From it you need to select "Device Manager".
- Left-click on "Start" and drive in the name of the desired directory.
If everything is done correctly, then a newA window with a list of all connected devices and a report on their operation. In this list, you need to find "USB-controllers". Next to the inscription will be the "+" icon. You need to click on it and see if it is not worth it to excuse an exclamation point device.
If one of the drivers does not work correctly, then click on it with the right mouse button and select "Update". After that, the system will try to find the necessary software on its own.
If this does not happen and the computer does not seeflash drive Windows 7, then the necessary drivers can be installed manually. To do this, you need to go to the site of the manufacturer of a removable drive and download the latest version of the software. After that, you can either start the file directly from the download folder, or go back to "Device Manager" and specify the path to the folder that contains the necessary drivers.
If the computer has stopped seeing the flash drive, you can use other ways to solve this trouble.
Windows Troubleshooting Tools
This method is not suitable in cases where the deviceis not generally determined by the system. If the computer sees the USB flash drive, but does not open the files stored on it, then in this case, the "Windows" itself will solve the problem.
To use standard toolstroubleshooting, you need to pull out the USB flash drive and insert it again. After this, the system usually notifies that it was not possible to install the software for the device and suggests trying to solve the problem.
If this function does not exist on the computer,do not despair. To do this, go to the official Microsoft website and download the necessary utility. After that, run it and click the "Next" button. The program will automatically begin to diagnose and correct possible malfunctions. As a result, the utility will give a verdict and offer several solutions to the problem to choose from. The user only needs to follow the recommendations of the program.
In some cases, standard toolsFault rectification issues a report stating that no faults have been detected. This means that the functionality of the utility was not enough to work. It can also be a sign that the problem lies in the most removable drive.
Sometimes in the folder "My Computer" the USB flash drive is not displayed for a number of other reasons.
Virus and spyware can also affectcorrect operation of the system. In this case, the most common errors appear on the screen are "Access denied". This means that the viruses and Trojans damaged the original device driver and replaced several files on it.
To solve such a problem, it is necessary to go into"Computer" and in the address bar enter the name of the flash drive (usually it's some kind of Latin letter), after it the symbols ":". Then press Enter. The next step is likely to open an empty folder. To make its files visible, just go to the autorun directory. To do this, select "Tools" and go to "Properties", after which a new window will open.
In it you need to find the "View" tab and scrollthe slider to the bottom. Having found "Hide files", you need to uncheck the option and activate the visibility of hidden files. After that it is enough to confirm the operation, and all necessary files should be displayed in the folder of the flash drive. However, that's not all. The fact is that after these manipulations in the folder "My computer" the flash drive is not displayed anyway, this is due to the fact that the file infected by the virus has not yet been deleted.
To get rid of it, you need to find a document withname autorun.inf and delete it. After that, it remains only to scan the system for possible malware. It is possible that the computer may have residual virus files.
If nothing has helped and the flash drive is not visible to the phone and the computer, you can try to do more complicated manipulations.
You can also try disconnecting from the computerall devices and restart the PC. After that, you need to scan it for viruses, switch the device off and on again and only then connect the USB flash drive. The fact is that the virus may not be on the PC itself, but on some additional device connected to it, so they need to be turned off.
If the device is not visible not only on the PC, but also on thesmartphone, then the problems can be more serious. As a rule, in this case, a message appears on the monitor indicating that the disk to be installed must be formatted. When you start executing the system requirements, you need to understand that this operation will destroy absolutely all data from the removable media. But along with the necessary documents, malicious or incorrect software will also be deleted.
To activate this process, just click on "Format" and wait until the system clears the flash drive.
To start the process of formatting manually, it is enough to perform the following manipulations:
- Go to "Properties" by clicking the right mouse button on "My Computer".
- In the drop-down menu, activate the format function.
- Choose a file system that will fully match the PC.
- Check the box next to "Fast". In this case, the files can be saved, but the "broken" folders will not disappear with them.
- Click "Start".
There are other reasons, guilty of the fact that the folder "My Computer" does not display a USB flash drive.
This happens when for some reasonthe system can not recognize the name of the flash drive. The fact is that a computer can have several disks installed. If the user assigns the name "K" to one of them, and the same index is installed on the removable media by default, this will lead to a crash. To solve such a problem is very simple.
To do this, go to the "Control Panel" andmake a selection by category (so it will be more convenient). After that, you need to find the administration panel and select "Computer Management". In this case, all manipulations must be carried out exclusively on behalf of the administrator. Otherwise, all operations will be futile, because the system will not accept the changes made.
There are 3 categories in the administration panel.From them you need to select "Memory devices". After opening a new window to the right, a list of all the disks registered in the system will be displayed. In this list there will be an anonymous device - this is a flash drive, whose name "did not please" OS.
To correct this small oversight, it is enough to assign a new index to the drive. To do this, you need to click on the unmarked flash drive with the right mouse button and select "Change letter".
After that, on a laptop monitora new window will appear, and the system will prompt you to change the letter. For a flash drive, the letter "A" is not recommended, since it is applicable only to floppy disks. For the same reason, do not use the "B" symbol. The index "C" is usually assigned to the main system partition of the hard disk. The letter "D" is responsible for the second logical partition, so it also does not fit.
All other symbols can be safely used for the drive.
Continuing to understand why you can not see the USB flash drive on your computer and how to solve this problem, it is worthwhile to consider several more options.
Replacing the Extension Cable
For USB-ports are often used all kinds ofsplitters. Such wires very often fail. With them happens the same thing that always happens with the headphones - the contacts go off or get malfunctioned, because of which it is impossible to use the accessory correctly.
This can happen if the PC wasAt the same time, too many devices are connected. In this case, it is recommended that you try to connect the flash drive directly to the computer. If it works correctly, then the whole thing in the extension cable. It's also worth trying to use a splitter with another device to check its performance.
Specialists recommend to purchase separate power supplies for extension cords, since sometimes the power supply in the "native" USB port of the computer may not suffice for the maintenance of such additional accessories.
However, sometimes it happens that even after all these manipulations, the computer does not see the USB stick. What to do in this situation? Do not despair. Perhaps the connectors for removable drives are simply disabled.
How to Enable USB Ports
Sometimes sellers for unknown reasons turn offConnectors using "thin" system settings. Perhaps this is done to ensure that buyers apply to them for paid services. However, you can handle everything by yourself.
To do this, you need to go into the BIOS.After that, go to the section responsible for the controllers and activate the connectors, if they are actually disabled. Typically, the necessary settings are in the Advanced section. To turn on the controllers, just use the arrows on the keyboard to select Enable in front of the USB Controllers line. Then just press F10 to save the changes. After that, it will only be necessary to load the computer in normal mode.
There is also a simpler explanation why the Windows computer can not see the USB flash drive.
A miniature device could fall to the floor or into the water. From the impact of his fragile parts are very easily damaged.
To test the performance of the USB flash drive,just insert it into the corresponding socket of the PC. If the light indicator does not light up on the drive and the computer does not produce the characteristic "you-dyk", then, perhaps, the accessory is damaged.
In this case, independently "reanimate"a flash drive will be very difficult. Of course, you can try to take it to a service center, where the specialist will be able to recover the data. That's why it's better not to store information on only one miniature media. Also experts recommend saving important data not on flash drives, but on removable hard disks. They are much less likely to break down and serve longer.
If the user purchased a flash drive frompopular manufacturers Kingston, Verbatium and others, it is worth to familiarize with the software that these companies offer. If you look at their official sites, then there you can find specialized utilities that will help to quickly restore the device. You can also search the Internet for something else from other manufacturers.
However, you should not download such programs from sites that are not related to the company that produces flash drives. In this case, you can get dangerous malicious software on your computer.
Knowing why a computer does not see a flash drive, thatdo and how to solve this problem, you can try to figure it out yourself. However, for the future it is worthwhile to take as a rule to use several drives at once. Only in this way can you be sure that important data and files will not be lost at the most unexpected moment. It is also timely to clean the PC registry and check it for viruses. Some of them may reside in system files. So do not forget about OS security.
