An information processing apparatus includes circuitry that retains firmware and performs processing based on the firmware, receives a command from an external device, and transmits a predetermined response to the external device as processing of the firmware in a case where the received command is a predetermined authentication command.

Information processing system, information processing apparatus and firmware program

According to one aspect of the disclosure, there is provided a storage device that includes: a storage medium; and circuitry that reads identification information stored on an integrated circuit card (IC card), and performs authentication using the identification information read by the circuitry and basic identification information stored in a specific area of the storage medium.

Storage device, information processing system, authentication method, and non-transitory computer readable medium

There is provided a magnetic disk device including a magnetic disk, and circuitry configured to receive a control command for instructing to write data in the magnetic disk or to rear the data from the magnetic disk, perform a data access process of writing the data in the magnetic disk or reading the data from the magnetic disk according to the received control command, specify a data amount of object data of the data access process, calculate a cumulative value of the data amount of the object data from a start of an operation, and perform notification when the cumulative value is equal to or larger than a predetermined threshold.

Magnetic disk device capable of predicting the probability of failure

A RAM disk driverreceives the user's specification for the capacity of a RAM diskvia an operation screen image(step S). The RAM disk driversets a continuous region in an OS invisible area, which is beyond management of an operating system installed in a computer, on a RAMfor a storage area of the RAM diskhaving the user's specified capacity (step S). When the user's specified capacity is greater than the capacity of the OS invisible area on the RAM, the RAM disk driverreduces the range of an OS visible area, which is managed by the operating system, on the RAMand sets the storage area of the RAM diskin the expanded OS invisible area. This arrangement effectively boosts up access to the RAMas the primary storage in the computer.

Method of accelerating access to primary storage and storage system adopting the method

After an initialization process (S), the access controller of the external storage device performs authentication using a password (S, S). If authentication is successful, the successfully authenticated state is saved, and the host computer is notified that the HD storage portion is accessible (S). Subsequently, it is decided whether SOF packets are being periodically sent from the host computer (S), and if periodic sending has been interrupted (S: NO), the connection to the host computer will be deemed lost, and the saved authenticated state will be deleted (S).

External storage device and method of controlling the device

A peripheral device of the invention is capable of data communication with a host device via one of a first-type interface and a second-type interface having different data communication-related specifications. The peripheral device has a single connector for making electric connection selectively with a first-type connector or a second-type connector. The peripheral device also has a controller for performing an initial connection process that makes a logical connection between the peripheral device and the host device via the first-type interface or the second-type interface. While the physical connection is maintained, the controller breaks the logical connection established by the initial connection process and subsequently makes another logical connection between the peripheral device and the host device.

Peripheral device and method of connecting peripheral device with host device

An electronic device has: an operation unit; a power supply unit; an input changeover switch; and a controller. The power supply unit is supplied commercial power and supplies the operating power to the operation unit. The input changeover switch switches between supplying or not supplying the commercial power to the power supply unit. The controller controls the input changeover switch. The controller includes: a power input portion; a control signal input portion; and a switching signal output portion. When the device power is being supplied from a master electronic device to the power input portion and the control signal from the master electronic device is received by the control signal input portion, the switching signal output portion outputs to the input changeover switch a signal instructing to switch and supply the commercial power to the power supply unit.
