Windows 10: A drive takes up a letter, doesn't appear in disk management

Hello
After reinstalling win10 i noticed that i have a drive that takes up a letter and it doesn't appear in disk management, so i can't change it's letter to something like Z: and hide it. It's nothing major but I'd just like F: to be the letter that pendrives get when i connect them.
Does anyone know how to change the letter of that drive with it not showing in disk management?
Thanks

:)

 

Problems assigning drive letter in Windows 10

I am running Windows 10. Within the past week or so I've had two problems assigning drive letters - I put them both in the post as they may be related.

First, when I assign a drive letter it takes anywhere from 30 minutes to an hour to complete. It doesn't seem to matter what external drive is involved or what letter I want to assign.

Second, the most recent time I tried to assign a drive letter (to an external drive previously used) I received a message that said "The operation failed to complete because the Disk Management console view is not up-to-date. Refresh the view by using the
refresh task. If the problem persists, close the Disk Management console, then restart Disk Management or restart the computer."

The drive in Disk Management shows a Healthy NTFS Primary Partition and the drive appears in File Explorer. First I tried restarting Disk Management. No change. Second I tried rebooting the computer. No change. Finally I tried doing Action | Refresh. The
line for Drive 4 completely disappeared from Disk Management. The full lines for disks 0-3 and the blank lines for disks 5-6 still appear. Every few minutes the line for disk 4 will show up again as a healthy partition, then it will disappear again a few minutes
later.

I wonder if the two problems may be related or where to go from here. When the Disk 4 line shows up in Disk Management, everything looks just fine with it.

 

Missing Drives On Windows Explorer

This is similar to what is happening on my home computer. Certain drive letters will not appear in Windows Explorer. I have to manually type the drive letter to list the contents. It affects the external hard drives and USBs that I connect to the computer
that automatically get assigned the next consecutive drive letter. They simply do not appear in Explorer, but show up in Device Manager with no issues.

If I use Disk Management and reassign the drive to a different letter, then the external hard drive appears in Explorer normally. It's only certain letters (like E: and F: and G that don't appear. They used to appear fine, but stopped a long time ago after
an update was applied.

 

Is it a network drive which has been mapped to a drive letter? If so,you can just right click the drive and remove it.

 

Will the drive appear when in some third-party software like AOMEI Partition Assistant or EaseUs or else?

 

An actual drive should appear in partition management software but I don't think a mapped network drive will.
