Claim 19:
20. The computer program product of claim 16, wherein the instructions stored by the non-transitory tangible storage medium are for performing the method further comprising re-computing a checksum value for the data object when a data segment of the data object is to be modified, said re-computing comprising:
generating a checksum for a data segment of the data object;
effectively subtracting the checksum of said data segment from the checksum of the data object to generate a first intermediate checksum;
modifying said data segment to generate a modified data segment;
generating a checksum for said modified data segment to generate a second intermediate checksum;
adding the first and the second intermediate checksums to generate a re-computed checksum value for the data object; and
detecting corruption of the data object based on the re-computed checksum.
