System and method for reassigning a storage location for reconstructed data on a persistent medium storage system

摘要

A system and method for reassigning a data storage location containing corrupted data to a new data storage location containing the reconstructed previously corrupted data. The system includes a persistent medium storage device such as a disk in electrical communication with a persistent medium storage device controller having a nonvolatile memory. Corrupted data, detected during a read operation, is reconstructed by the system and the reconstructed data is written to nonvolatile memory. An indicator is set in a location in nonvolatile memory indicating that the reconstructed data is being written to a reassigned location on the persistent medium storage device. The persistent medium storage device then reassigns the storage location for the reconstructed data and the reconstructed data in nonvolatile memory is written to the reassigned location. Once the reconstructed data is written to the reassigned location, the indicator in nonvolatile memory is reset.
