A method for calculating checksums includes calculating a first checksum based at least in part on a first block of data, and calculating a partial checksum based at least in part on a second block of data. The second block of data comprises a data portion followed by a fill portion, the fill portion having a length equal to a length of the first block of data. The first checksum and partial checksum are combined to form a second checksum for a total block of data, the total block of data comprising the first block of data and the data portion of the second block of data.
