By default, Windows 10 hides removable drives that are not currently connected to the computer. However, you can change this setting to show the drive names even when the drives are not connected. Here are the steps:
Open File Explorer by clicking the folder icon in the taskbar or by pressing Windows key + E on your keyboard.
Click on the "View" tab in the top menu bar and then select "Options" on the right-hand side.
In the Folder Options window, click on the "View" tab.
Scroll down until you see the "Show hidden files, folders, and drives" option and select it.
Uncheck the box next to "Hide empty drives in the Computer folder" and then click "Apply" and "OK" to save the changes.
Now, even when your removable drives are not connected, their names will still be visible in the Computer folder in File Explorer
