windows - Unable to safely remove my harddrive since explorer.exe is holding on to it

I am Unable to safely remove my harddrive since explorer.exe is holding on to it. I tested this with process explorer and it says there is a handle to F: being used by the explorer.exe.

I restarted explorer.exe and it still does not go away.

Then I see that in my explorer that there is an additional F: being shown. I am not able to explain hence please see the below image

I think its that additional F: apart from my drive name Sethu Entertainment that is causing the issue. I was not able to remove this, try as I might.
