The computer does not see a flash drive

Of all the methods of transferring information, the most convenient and widespread in the world has long been copying using flash drives, or as they are called in Russia - flash drives. Almost every adult has at least one such device. And it's not surprising that, despite the simplicity, these useful things sometimes cause problems.

If the computer does not see the flash drive that you received from the neighboring department or from the client, but this media has important data that must be transferred to your computer at all costs, then it is necessary to find the reason for this strange behavior of your car.

Unfortunately, flash drives, like any other electronic devices, sometimes fail, this is inevitable, since the very concept of flash memory implies that sooner or later the number of write cycles in cells will reach its limit and the carrier will begin to collapse. But such cases, when the source of the problem is the carrier itself, are not considered in this article. We'll talk about situations when the computer does not see the USB flash drive due to the problems that arise in it. Since often a completely working flash card suddenly ceases to be determined precisely by the fault of the PC.

By the way, most often the computer does not see the USB flash drive due to the lack of drivers in the system that support this particular model. All major corporations that produce mobile equipment have their own programs for computers. To make your PC friends with the phone, you need to go to the manufacturer's website and download this application.

Where should I start looking for reasons if the USB flash drive does not want to work with your PC? First of all, it is necessary to check and cut off the most frequent variants, because of which such failures of the system are quite possible. Make sure that the USB flash drive is inserted correctly, to the end.

Then check how the drive LED behaves, if it flashes when connected, but the message about the appearance of the new device does not pop up, so the hardware of the computer can be seen on the flash drive, but the operating system fails, therefore the problem lies in the OS.

If the device does not blink at all, then, most likely, a fault at the level of iron. Or the computer does not work as it should, or USB is disconnected through the BIOS, or the USB flash drive itself is damaged, by the way, it's very easy to check it by inserting it into another computer, you will immediately determine what's the matter. If the problem is in the flash drive, then it should be replaced, if on another PC it works fine, then we will go further.

A frequent cause of the situation in which the computer does not see the flash drive at the level of "hardware" is the lack of power on the USB bus. This happens when you have several devices involved at the same time. For a new connection, just not enough current. If you suspect that in your case a large number of USB devices can provoke a failure of the flash drive, try temporarily to disconnect all extraneous devices.

It also happens that the computer does not see the USB flash drive and generally completely ignores the USB connections to the front panel connectors. In 95% of cases, low-quality wires coming from the front to the motherboard or incorrect connection of the contacts are to blame for this. It is possible that the front panel is not fixed at all. In any of these cases, it's enough to try to insert a USB flash drive into any of the rear USB connectors. This will make sure of fairness or on the contrary to refute the suspicion about the inoperability of the front panel.

Sometimes the PC hardware sees the drive, but its OS can not connect correctly, and eventually the computer does not see the USB flash drive for the simple reason that the drive letter assigned to it is already taken. The most offensive is that the system, it would seem, must quickly correct this misunderstanding, but it can not for some reason only known to it. To resolve this situation is simple enough. Right-click on "My Computer" there choose "Management" and in the opened window we search for a line "Disk Management". Clicking on it, go to the list of disks and look for a flash drive. Right-click on it, look for the option "Change drive letter" and choose any free letter. That's it, your flash drive works again!
