Notes/Warnings

For removable medias, FSDev_Query() will return a valid value for the State and Fixed members of p_info even if the media is not present, Size and SecSize will be set to 0. In such cases an error will be returned stating the reason why the device was unaccessible. Otherwise, if a fatal error occurs or the device is not opened an appropriate error will be return and the content of p_info will be invalid.
