Abstract

An arrangement of apparatus for safely writing data and parity to multiply-redundant storage comprises a first storage component operable to store at least a first mark in a storage device to index uniquely a pattern to be written by at least a data write; a write component operable to perform the at least data write; a further storage component operable to overwrite a mark in the storage device with at least a further mark to index uniquely a pattern to be written by a parity write; and a further write component operable to perform the parity write. Preferably, the first storage component comprises a second storage component operable to overwrite said at least first mark in said storage device with a second mark to index a pattern to be written by a first parity write; and the write component is further operable to perform the first parity write.
