A computer system and process involves entry into a RAID storage array of a digital computer system, at a succession of date/time instances, a succession of records of electronic documents, some of which may have corresponding physical originals, assignment of attributes to the records in any data-type formats that characterize the documents, assignment of a succession of unique date/time identifiers to the succession of records in correspondence with the date/time instances of their entry, selection of a range of date/time instances that correspond to a range of the records of documents that are known to be uncorrupted, and selection of groups of electronic documents having logically related attributes within the range of the uncorrupted documents.
