Windows 10: "The operation is not supported by the object" - Disk Manager while extending partition volume

HiI am trying to extend the volume of a partition on an external drive. After completing the wizard, I get this:I selected "yes", and then I get this error:The drive used to be the hard drive of a PC, but I've turned it into an external drive. I'm using Windows 10 Home with an Admin user. I have searched online, but I cannot find anything useful .Here are some more screenshots that may come in use:

Extend Volume in disk managment not working

Hi,



Thank you for posting your query in Microsoft Community. Let me help you.

• 
  Since when did the issue started appearing?
  
• 
  Have you made any changes in settings prior to the issue?
  
• 
  Do you receive any error code or error message on the screen?
  

I suggest you to follow the exact steps mentioned below and check if you are able to perform the action.

• 
  Run Disk Management. Open Run Command (Windows button +R) a dialog box will open and type "diskmgmt.msc".
  
• 
  In the Disk Management screen, just right-click on the partition that you want to shrink, and select “Extend Volume” from the menu
  
• 
  Locate your system partition — that’s probably the C: partition. Right-click on it and select “Shrink Volume.” If you have multiple partitions on your hard drive, you could also choose to resize a different partition to free up
  space.
  

Check if it helps.



Please reply with the details and updated status of the issue. We will be happy to assist you further.
