DISK FAULT RECOVERING METHOD, DISK DRIVER, AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a disk fault recovering method, a disk driver and a disk which are applicable to even an inexpensive stand-alone type computer device by dividing the disk into areas and automatically duplexing data. SOLUTION: The disk driver 2 sends a command to a disk device and receives a stylus from the disk device to control access to the disk 1. The disk 1 is divided (partitioned) into a system block where an OS and application programs are stored, a data block 12 where data are stored, and a backup block 13 where the same data as the data written to the data block 12 are stored and the disk driver 2 actualizes mirroring for even a disk device which does not have disk array structure by writing the data to the data block 12 and backup block 13 to make a fault recovery of data.
