If Windows cannot recognize or format the USB drive properly, there may be a problem with the operating system or the USB drive. If the problem is in Windows, you can solve it by reinstalling the USB driver. If the problem is with the USB drive (and it’s not damaged), you can fix it with an advanced formatting process.
Steps
First way

Plug the USB into the computer and open Disk Management. This Windows utility allows you to manage all connected drives. Even if the USB drive is not properly formatted, it will also appear in this utility.
- Press the Windows + R combination and type diskmgmt.msc to run the Disk Management utility.
- Find the USB in the list of connected drives. If your USB is listed here, it may not be formatted properly. Click for instructions to format the drive. If your USB is not showing up, read on for troubleshooting.

Plug the drive into another USB port. Before continuing, the fastest way to identify the problem is to try plugging the drive into another USB port on your computer. You must plug it directly into the port on your computer, not the additional USB ports.
- If the drive works on another USB port, the first port is probably damaged. There is nothing you can do but replace the motherboard. In the short term, you need to avoid using this port in the near future.

Plug the USB into another computer. If the drive still doesn’t show up when you plug it into another computer, the USB might be damaged. You need to buy a new USB drive.
- If the drive shows up when you plug it into another computer, there may be a problem with the driver on your computer. See the next section for how to troubleshoot driver problems.
