How Could You Solve 8021 Error in an Easy Way

Cause of 8021 Error
    8021 Error is brought when Device Manager calls off a hardware device because the hardware reported to Windows that it's having some kind of unspecified problem.

Manual Solution to fix 8021 Error
    To resolve 8021 Error, do the following.

    To start Device Manager, click Start, click Search programs and documents, and then click Device Manager. A list of available matching items appears above the search box; click Device Manager. Device Manager opens with your computer name at the top and a list of devices that are installed on your computer beneath your computer name.

    Locate the malfunctioning device in the list of devices, right-click the device, and then click Uninstall. When a warning message arises that you are uninstalling a device from your system, click OK. Device manager uninstalls the device.

    Right-click your computer name in Device Manager and click Scan for hardware changes. Device manager scans your system and automatically reinstalls your device.

    Right-click the device and click Properties. On the General tab of the device Properties dialog box, in Device status, you should see the message This device is working properly.

    If the methods above do not resolve the problems with the device, and if the device is an external drive, such as a USB flash drive or external hard drive, use the taskbar icon to safely eject the device, then unplug the device from the computer.
