A method and an apparatus for detecting a state of a removable medium installed in an electronic apparatus is provided. The electronic apparatus includes a detection device, a non-volatile storage device, a state change detection device, and a first notification device. The detection device detects a state of the removable medium and creates state data. The non-volatile storage device stores the state data. The state change detection device detects a change of the state of the removable medium by comparing state data stored during a first power-on period to state data stored during a second power-on period, where the first power-on period and the second power-on period are separated by a power-off period. The first notification device produces a first notification if the state change detection device detects the change of the state of the removable medium.
