Abstract
A device is connectable to a computer using a data string based on the SCSI standard. The device includes a mode switching section configured to switch the device to one of a first mode and a second mode in which an access to the storage device with a standard SCSI commands is permitted and prohibited, respectively. When the standard SCSI command is received and the device is in the first mode, the physical storage area of the data storage section is accessed on the basis of the SCSI command. When the standard SCSI command is received and the device is in the second mode, a pseudo response is transmitted to the computer, which indicates that no storage medium is mounted. When a particular SCSI command is received, the file is accessed through a file system provided in the device based on the particular SCSI command.
