Why does my computer does not see the USB flash drive ?

Look what came before progress - at a small fee fit hundreds of gigabytes of memory!Today, instead of the relatively bulky hard drives we can use flash cards, which are often characterized by no less volume.Furthermore, the procedure they are easier to manufacture, less expensive and far less likely to break.However, they are also sometimes does work.Why?What to do in this case?And that we'll find out right now.

Faults can be very different, and often the problem is not from the card and from your PC or laptop.In order to check on the serviceability of the stick, it is necessary to connect to USB-port.Carefully look at the device - if lit LED signal, a memory stick is all right, as well as with the port itself.Theoretically, mechanical failures are eliminated, so the case is likely in the operating system of your computer, such as problems with the drivers - they can be reinstalled, but by default they are installed automatically.When the signal on the device does not flash, then it is a problem ..

. However, let's order.

Possible causes

  • fault is often part of the computer does not see the device as USB-port to which you connect it, just not connected to the power supply!Or just not enough power supplied to it.The solution is simple - plug in a USB flash drive to another port, of which there can be a great variety of both the front and rear panels.
    way, about the lack of power - the problem is urgent, as a rule, older laptops and solve it you hardly ever happens.Sometimes food can be missed in case connected to the ports at once a large number of devices.Try unplugging some of them and then, perhaps, your card will start to work.
  • continue.Try to go into the BIOS and check whether there is USB support is included?In some cases it can be disengaged, for example, during a power failure.In addition, in this case, the attached USB flash drive is usually not recognized by the computer, and instead of the icon Safely Remove Hardware, you will see an exclamation point in a yellow triangle.
  • Well, when the hand is a laptop.Right there you can test the functionality of the card - if it is not willing to work, then, just broke.What to do in this case?You can just forget about it, if it does not contain valuable data - a new flash card will cost only a few hundred rubles.But if it were desired data, then you have to seek help from a company engaged in a professional data recovery.Make it yourself you are unlikely to succeed - high risk to lose all data permanently.
  • As for the drivers, then this problem does exist, but it is typical for older computers.As a rule, they need to be updated motherboard drivers that you can download on the official website of the manufacturer.But we would not advise you to download them from other resources - can carry the virus into the system.By the way, to find out the name of the motherboard, if you do not remember, it is possible with a special free utility, which can be found on the Internet.
  • Another option - if your system is connected flash assigns it the name of an existing disk.However, this difficulty is solved rather simple way.You will need to go to "Control Panel", select "Administrative Tools" and then "Computer Management."In the window that opens, click on the item "Storage", then -. "Disk Management"Now in front of you you will see a full list of your system's disks, among which must be flash card.Click on it, click on the right mouse button, the "Change Drive Letter and Paths ..." and choose any letter is not assigned.After this, the computer would have to see the stick, of course, if she is in working condition.
  • Often the reason is the presence of the virus in the system.What should be done?The answer is obvious - use Antivirus.Initially, however, it is imperative to update the database to the latest version, and only then start looking for suspicious and malicious files.If you do not have anti-virus or simply do not have enough money to buy it, you can use a free utility for example, AVG Anti-Virus Free Edition or McAfee Free.
  • Sometimes the problem lies in the drivers to the flash drive itself.Check out this simple enough - on the desktop, place the arrow on the icon "My Computer", click on the right mouse button and select "Properties" item.Appears in the window with information about the system.Select the "Hardware" tab and then "Device Manager."Then select "USB controllers are Universal Serial Bus" and look carefully, is there a yellow icon next to at least one controller.If there is, then you need to remove the driver, and then reinstall it.As a rule, when you restart the operating system will ask you to install the necessary drivers.If this did not happen, which is unlikely, then download them to the manufacturer's website.
  • Quite often there is a conflict of file systems, for example, when the file system is FAT32 USB drive and your computer - NTFS.Only one way out - to format the flash drive to NTFS (or vice versa).But remember that when you format all of your data is permanently deleted!Be careful!

What we have in the end?If the problem concerns a computer, it is often possible to solve it yourself.And if the problem lies in the performance of flash cards, then revive her own efforts are unlikely to succeed
