Update Assistant does not detect External Storage Device

I am currently facing an issue with the update assistant. The problem comes from the prompt as seen from this webpage

Free up space for Windows updates - Microsoft Support

The issue is in "Step 2: Connect an external storage device". It says to
"Connect your external storage device and wait until you see it in the drop-down list" but the external storage device already connected to my device (and shows up on My PC) is not shown on the drop down list. Can you help?

 

Quirky behaviour with external HDD

Since you have already checked Device Manager and did not see any errors, we suggest that you manually uninstall the device drivers for your external drives. Doing this will allow the system to install the driver for your external drive automatically and
correct any error. You can follow the steps below to uninstall the device driver:

• Search for Device Manager via Cortana and hit the
  Enter key.
• Go to View, and click Show hidden icons.
• On the Device Manager, check under Universal Serial Bus Controllers (if the drive is connected via USB). The drive should appear as a USB Mass Storage Device.
• Uninstall the USB Mass Storage Device listed in the Device Manager.
• Restart your PC.
• After restarting, allow the default USB Mass Storage Device drivers to be automatically downloaded by windows. Make sure that you are connected to the internet for this process to push through.
• Reinstall all other drivers from the support website of your External drive.

We look forward to your response after completing the steps.

 

External Drive using storage spaces does not work on my new Win 10 PC?

Hi Leo,

Storage Spaces not only increase storage over time as you add drivers to your PC, it will also help you in protecting your data from drive failures. To isolate your concern, we'd like to know if you were getting any error messages when trying
to connect the external drive to your new PC. Also, can you tell us what troubleshooting steps have you tried so far?

In the meantime, we suggest that you run the Hardware and Devices troubleshooter to perform a diagnostic process on your system that will check and fix issues related to Storage Spaces. To do this, please follow the steps below:

• Type troubleshooting in the Search bar, then press
  Enter.
  
• Click View all from the left pane.
  
• Locate and click Hardware and Devices to run the troubleshooter then follow the next steps.
  

Furthermore, here is a link for more information about the Storage
Spaces in Windows 10.

We'll be looking forward to your response.
