ABSTRACT:
A system and method for comparing mass storage devices. Generally, a mass storage device is subdivided into data blocks representing physical storage locations of some particular size. For each one (or group) of data block(s), a digest is calculated, wherein the digest is an alternate representation of the data stored within the data block(s). A digest is highly dependent on the data it represents such that different data is extremely likely to result in different digests. This high dependence allows for comparing digests rather than directly comparing the data stored at each data block. Furthermore, by calculating a digest that requires fewer bits than the data block(s) it represents, the amount of data that must be transferred between mass storage devices during comparison is minimized.
