Sometimes the computer refuses to recognize the USB flash drive, which makes it impossible to work with documents on this medium. This problem occurs for several reasons.
Often the reason why the computer does not see the USB drive is a malfunctioning connectors. Make sure the indicator light on the USB stick is blinking. This is a signal that an electric current is passing through the connector. If there is no light signal, move the USB flash drive to another port, if any. If the computer still does not see the USB drive, the problem is most likely with the USB flash drive connector.
If the indicator light on the flash drive comes on, but computers do not recognize it, most likely the problem is a malfunction of the USB drive. To extract information from such a flash drive, you should contact a specialist.
If the computer displays the message "USB device not recognized", the system probably assigns the USB flash drive a letter already occupied by another drive. To fix this problem, open the "Control Panel" and go to the "Administrative Tools" section by selecting the "Computer Management" tab. Next, open the "Disk Management" section. In the list of all available disks, find the USB flash drive. Click on this line with the right mouse button and select "Change drive letter". Specify a free letter in the system and click OK.
Sometimes there are no special drivers on the computer, so it cannot read the USB flash drive. This guess can be checked by going through the "Control Panel" in the "Device Manager" section. In the list that appears, find the item "USB Controllers". If there are no USB drivers, the drive will be highlighted in yellow. Drivers must be downloaded from the manufacturer's website and installed on the computer.
Viruses in the operating system can cause a wide variety of computer problems. Sometimes they prevent the USB disk from working properly. In this case, you need to scan the hard drives with an antivirus program and remove viruses.
