Post-failure replacement takes place when the hard drive breaks unexpectedly before a pre-failure replacement can take place. The data on the failed drive must be rebuilt from the parity data on the remaining active drives and written to a hot spare. Post-failure replacement takes considerably longer due to the calculations that must take place to rebuild the data.
