RAID 5 (Redundant Array of Independent Disks) creates a fault-tolerant storage solution by writing small chunks of information across multiple disks at the same time while also writing recovery information to the same disks. If a drive in the RAID 5 array fails, there is no loss of data as long as the failed drive is replaced. Microsoft Windows Server 2008 with software RAID 5 configured features the Disk Management and Diskpart utilities for assistance should a RAID 5 hard drive fail. Remove and replace a failed drive from a Windows Server 2008 computer and rebuild the array using utilities included with the operating system.
