AmigaOS would have both a name for the physical device like df0: and dh1: above but also a label or volume name which could be work: or something and those would mostly be interchangeable from the shell to refer either to "any volume named foo:" or "whatever disk is in drive0 right now".
AmigsDOS was an odd bird that used things like df0: (drive, floppy, 0) and dh1: (drive, hard, 1.)
