    Thank you for the update and I apologize for the late response.

    I appreciate if you could answer few questions to narrow down to the issue.

    • How exactly you are trying to unmount the drive. Is it through Command prompt or from Disk management?

    • What exactly happens when you try to unmount?

    • Did you receive any error message while trying to unmount?
    I suggest you to try the steps given below and check if it helps.

    Please close all the Windows before trying the steps.

    • Open Disk management.

    • Right-click the mounted drive that you want to remove, and then click
      Change Drive Letter and Paths.

    • Click Remove, and then click Yes.
    Hope the information helps. Let us know if you need further assistance. We will be happy to help.

    Thank you.

    Usually, this problem occur due to software incompatibility or corrupted USB drivers. For us to better assist you, we would like to clarify the following:

    • Have you made any recent changes on your computer prior to the issue?
    • Which driver did you uninstall? Have you reinstall the driver? If yes, how did you reinstall the driver?
    • Have you check if the external HDD is visible in Device Manager?

    If the issue still persists after uninstalling some games, we suggest that you run the troubleshooter for hardware and devices. If you're using the latest Windows 10 version, follow these steps on how to run the Hardware and Devices troubleshooter:

    • Click the Start button and select the Settings
    • Choose Update & Security from the list.
    • Click Troubleshoot in the left pane of the window.
    • Under Find and fix other problems, select Hardware and Devices and click
      Run the troubleshooter.

    We're looking forward to your reply.
