Abstract

PURPOSE:To improve the reliability of disk write by reading data from a disk when a write operation is executed according to a disk write request and returning a normal finish status when the data is normal, or an error finish status when it is abnormal, to a CPU. CONSTITUTION:The microcomputer 30 of a disk channel device 3 controls a data transfer control circuit 32, and performs read or write to a magnetic disk 6 through a disk controller 5. When all the data of a buffer 33 is normally written, the write is automatically read at once by a firmware 31, and stored in the buffer 34. At that time, the confirmation of a read error is performed. The normal finish status when it is normal or the error finish status when it is abnormal, is returned to the CPU 2. Thus, the reliability of the disk write operation is improved without imposing a burden on a software.
