Abstract
A method and apparatus for generating checking data, an electronic device and a non-volatile computer-readable storage medium. The method includes: acquiring a store-status matrix corresponding to a redundant array of independent disks; determining non-reference vectors among the magnetic-disk vectors, and performing data-vector-element evenly dividing processing to an initial data region formed by the non-reference vectors, to obtain first and second data regions; performing data-exchange processing to the first and second data regions in the store-status matrix, to obtain a first matrix; determining a plurality of second-order matrixes in the first and second data regions of the first matrix, and performing position-exchange processing to target magnetic-disk elements in the second-order matrixes, to obtain a second matrix; based on the second matrix, performing single-error-correction encoding generating processing, to obtain first checking data; and based on the second matrix, performing double-error-correction encoding generating processing, to obtain second checking data.
