Abstract: A system and method for initializing large portions, or extents, of a mass-storage device in the background so that such overwriting processes do not significantly affect latency as experienced by a host. The method extends the use a system intended for background copying of data from a source extent to a destination extent to that of initializing an extent on a mass-storage device. It does so by causing the system to treat the defined extent as both a source extent and as a destination extent simultaneously.
