External storage devices such as USB flash drives are commonly used to store and share data across computers. In general, these devices are automatically recognized when plugged into the computer, but there are some instances where external devices do not show up in your My Computer folder. If your PC is not recognizing your USB mass storage device, there are several methods you can use to find your USB key, external HDD or pen drive.
What To Do When Your USB Isn't Detected
Connect your USB drive to your PC and open the Control Panel
. Open the Device Manager
and click on the Scan for hardware changes
button. This will force your computer to search for the USB key:
If the above solution doesn't work, go back to the Device Manager
and expand the USB Serial Bus controllers
section. Right-click on the faulty USB device and select Uninstall
to uninstall its driver:
Once done, restart your computer and let Windows reinstall the missing driver. If the problem persists, go to the Control Panel
> Administrative Tools
. Search for the Shell Hardware Detection
service and set its Startup Type
Repeat the operation for the Plug and Play
When finished, close the Services
utility and restart your computer.
