TECHNIQUE FOR INFORMATION PROTECTION ON FAULT-TOLERANT REDUNDANT INFORMATION STORAGE DEVICES The present invention relates to a technique which provides swift and easy error correction and detection on one or more fault-tolerant redundant storage devices. In the present technique, an information packet including (a) the destined storage location identifier in a first section, (b) the information in a second section, and (e) a unique monotonically increasing number in a third section, is sent by a processor to one or more redundant storage device controllers for storage in relative locations of the redundant storage device(s), where the monotonically increasingnumber is incremented and applied to each sequential information packet to be stored on the redundant storage device(s). When relative storage locations of the redundant storage device(s) are subsequently read and the information is found not to match, an error has occurred on one of the storage device(s), and if the storage location identifier on the compared information packets are also found not to match, then the information packet including the correct storage location identifier is used However, if the storage location identifiers are found to match, then the compared information packet with the higher monotonically increasing number is deemed to contain the correct information.
