The spring-loaded door covers part of the disk slot, which allows the insides of the docking station not to gather dust if a small (2.5 ") disk is inserted. But it would be better if the door was made without a cutout (like the cartridge slot on some old game consoles) so that dust does not fly inside the docking station when no disc is inserted at all.
