Patent abstract
A method for assuring the integrity of stored data in a storage system is provided. At a specified time at which further writes to a desired portion of the stored data are to be precluded, a hash value is calculated for the desired portion of stored data. At a later time, retrieval of the stored data is performed and the hash value recalculated. A comparison of the former and present hash values reveals whether the data has remained unchanged.
