Make sure the drive is selected and click Remove. The drive should be highlighted in blue when it is selected. Clicking Remove removes the drive letter from the drive. An alert will appear.

Click Yes. It's in the alert that appears when you remove the letter of the disk drive. The alert informs you that some programs may not work properly if the letter is missing. Click Yes to continue. This removes the letter from the disk drive. Removing the drive letter from the disk drive will prevent it from appearing in File Explorer. If that's all you want, you can stop here.

Make sure the drive is selected and click Add. The drive should be highlighted in blue when it is selected. Clicking Add displays options to add a new drive letter, or mount the drive in a different location.

Click New Folder. It's to the right in the "Browse for drive path" window.

Type a name for the folder and click Ok. This creates a new folder for the drive location. Give the folder a name you can remember, such as "Secret Drive" or "Hidden Drive."

Click Ok. This will allow you to access the disk drive by clicking the mount folder you selected in Disk Management. For additional security, you can hide the folder that contains the drive mount location in File Explorer. That way it will only appear if show hidden files and folders in File Explorer.
