摘要： PROBLEM TO BE SOLVED: To provide a data writing method, a data verification method, a computer control method, a computer, a disk array system, and a disk drive by which omission of data writing by sector can be further surely detected.
SOLUTION: In each of a series of sectors of a recording medium to which data are written caused by a request for writing data, positional information indicating the position of the sector in the series of sectors, and common information which changes whenever writing of data to a series of sectors occurs and is set connecting to a series of sectors, are written into. Consequently, a problem is solved that, when writing of data to a recording medium is not normally carried out due to shortage of head voltage or dust attached on the recording medium in writing, the mechanism for detecting omission of data writing by sector is not satisfactory in a conventional error detection method.
