By default, the Mac desktop will show external drives and volumes, including things like external hard drives, USB flash keys, and other external storage. If you wish to not show those external volumes on the desktop, you can adjust a setting in MacOS to hide external drives form the Mac desktop.
Hiding external drives from the Mac desktop offers a cleaner and more simplified desktop experience, and you can continue to access the external drives and volumes from the Finder at any time.
