Double-Erasure Correcting Code Methods for Parity Disk to Recover Failure Data

Abstract— In a redundant disk array the protection of data against disaster disk failure is very critical. Nowadays, single disk is highly responsible when a redundant disk array failure occurs. The results saving several other disks and reduce the probability of failure that at least one disk will fail. The data is distributed on several disks and the distributed data are store an independently. We present a double-erasure correcting code with proved theorem and evaluate code to recover a failure data from parity disk.

Index Terms— Redundant array of Independent Disk (RAID), Parity Disk Architecture, Parity in t dimension Double-Erasure Correcting Code with proved theorem.
