A disk drive assembly includes a chassis adapted to be fixed on a computer housing, a module-mounting seat rotatable on the chassis between an exposed position and a concealed position, and a disk drive module attached to the seat. When the seat is disposed at the exposed position, the module is exposed within an opening in the computer housing, thereby permitting insertion of a recording medium into the module. When the seat is disposed at the concealed position, the module is deflected from the opening and is concealed entirely within the computer housing.
