Abstract

PURPOSE:To restore the information of a disk updated halfway even when a processor is downed during the writing of the disk by using a presence decision flag indicating the presence of writing information and a buffer. CONSTITUTION:When an information processor 7 write in the disk 1, a control program 6 activates a buffer writing instructing processing part 5, writes in the buffer 3 and sets the information presence decision flag 2. Then, the program 4 activates a disk copy request part 6, transfers the information on the buffer 3 to the designated address of the disk 1, and then cancels the information presence decision flag 2. At the time of generating a trouble in the processor 7 during the writing in the disk, a trouble processing program 8 is activated to read the state of the information presence flag 2 from the disk 1, when the flag is set, the control program 4 activates the disk copy request part 6, transfers the contents of the buffer 3 to a designated address area to cancel the decision flag 2 and release the disk.
