PURPOSE:To identify a data saving by a file controller at high speed by providing a flag part to indicate the data saving by the file controller. CONSTITUTION:When a file controller 1 data-saves the file data of a file storage device 3 inside to a magnetic disk device 7 for a data saving through a data saving driving part 5, a flag is set to a data saving flag part 6. On the other hand, by corresponding to the command of a host device, when an instruction is issued through a file controller 2, the controller 2 judges that the flag is set to the flag part 6, and starts the execution of the command. However, since when a data saving control part 4 practices a data saving action, the flag of the flag part 6 is resetted, the reception of the command is avoided. |
