Abstract
Exemplary method, system, and computer program product embodiments for an incremental modification of an error detection code operation are provided. In one embodiment, by way of example only, for a data block requiring a first error detection code (EDC) value to be calculated and verified and is undergoing modification for at least one randomly positioned sub-blocks that becomes available and modified in independent time intervals, a second EDC value is calculated for each of the randomly positioned sub-blocks. An incremental effect of the second EDC value is applied for calculating the first EDC value and for recalculating the first EDC value upon replacing at least one of the randomly positioned sub-blocks. The resource consumption is proportional to the size of at least one of the randomly positioned sub-blocks that are added and modified. Additional system and computer program product embodiments are disclosed and provide related advantages.
