Abstract:
1. An insertion/removal detector, comprising: an insertion detection section which is adapted to detect that an adapter into which an external memory is inserted has been inserted into a connector for inserting the adapter; a first identification information acquisition section which is adapted to acquire first identification information to identify first external memory which the insertion has been detected by the insertion detection section; a first external memory information acquisition section which is adapted to acquire first external memory information concerning the first external memory; an access request section which is adapted to send an access request to the first external memory; a second identification information acquisition section which is adapted to acquire second identification information to identify second external memory inserted into the adapter inserted into the connector at the time of the access request; an identification information comparison section which is adapted to make a comparison between the first identification information and the second identification information and to determine whether or not they are identical; a first file organization information acquisition section which is adapted to acquire first file organization information concerning file organization of the first external memory; a second file organization information acquisition section which is adapted to acquire second file organization information concerning file organization of the second external memory if the identification information comparison section determines be identical; and a file organization information comparison section which is adapted to make a comparison between the first file organization information and the second file organization information and to determine whether or not they are identical; a second external memory information acquisition section which is adapted to acquire second external memory information concerning the second external memory if the identification information comparison section determines not identical or if the file organization information comparison section determines not identical.
