Automatic data recovery (rebuild) When you replace a hard drive in an array, the controller uses the fault-tolerance information on the remaining drives in the array to reconstruct the missing data (the data that was originally on the replaced drive) and write it - HP 353803-B22 | HP StorageWorks 1000 Modular Smart Array maintenance and service - Page 103
