Creating a Mirrored (RAID 1) Set using Disk Management
Begin the process by invoking the Disk Management snap-in. This can be achieved by typing '''compmgmt.msc''' at a command prompt window or Run dialog and selecting Storage -> Disk Management. The system used in this example contains three disks numbered 0, 1 and 2 respectively. Disk 0 is the system disk and disks 1 and 2 will be used to create a mirrored set.
Within the Disk Management tool right click on the unallocated space in the graphical view of the first disk to be used in the stripe mirror set and select ''New Mirrored Volume...'' to invoke the ''New Striped Volume'' wizard. Click ''Next'' on the welcome screen to proceed to the disk selection screen. As mentioned previously, a mirrored set must be comprised of two disk drives. Initially, the wizard only lists the currently selected disk in the ''Selected'' column. In order to proceed, one more disk is required. To add a disk to the mirrored set, select a suitable disk from the available disks in the right hand column and click on ''Add'' to add it to the selected disks list:
