Creates a RAID-5 volume using three or more specified dynamic disks. Syntax: CREATE VOLUME RAID SIZE= DISK= , , , ,. ALIGN= ...

    Creates a RAID-5 volume using three or more specified dynamic disks.

Syntax:  CREATE VOLUME RAID [SIZE=] DISK=,,[,[,...]] [ALIGN=]
            [NOERR]

    SIZE=    The amount of disk space, in megabytes (MB), that the volume
                will occupy on each disk. If no size is given, the largest
                possible RAID-5 volume will be created. The disk with the
                smallest available contiguous free space determines the size
                for the RAID-5 volume and the same amount of space is allocated
                from each disk. The actual amount of usable disk space in the
                RAID-5 volume is less than the combined amount of disk space
                because some of the disk space is required for parity.

    DISK=,,[,[,...]]

                The dynamic disks on which to create the RAID-5 volume. You
                need at least three dynamic disks in order to create a RAID-5
                volume. An amount of space equal to the size specified in
                SIZE= is allocated on each disk.

    ALIGN=   Typically used with hardware RAID Logical Unit Number (LUN)
                arrays to improve performance. Aligns all volume extents to
                the closest alignment boundary. The extent offsets will be
                a multiple of . 

    NOERR       For scripting only. When an error is encountered, DiskPart
                continues to process commands as if the error did not occur.
                Without the NOERR parameter, an error causes DiskPart to exit
                with an error code.

    After you create the volume, the focus automatically shifts to the new
    volume.
    
    Fault-tolerant volumes such as RAID-5 and mirrored volumes are not
    supported in any edition of Windows Vista.

Example:

    CREATE VOLUME RAID SIZE=1000 DISK=1,2,3
