create

Creates a partition or shadow on a disk, a volume on one or more disks, or a virtual hard disk (VHD). If you're using this command to create a volume on the shadow disk, you must already have at least one volume in the shadow copy set.

Syntax

create partition
create volume

Parameters

Parameter	Description
create partition primary command	Creates a primary partition on the basic disk with focus.
create partition efi command	Creates an Extensible Firmware Interface (EFI) system partition on a GUID Partition Table (gpt) disk on Itanium-based computers.
create partition extended command	Creates an extended partition on the disk with focus.
create partition logical command	Creates a logical partition in an existing extended partition.
create partition msr command	Creates a Microsoft Reserved (MSR) partition on a GUID partition table (gpt) disk.
create volume simple command	Creates a simple volume on the specified dynamic disk.
create volume mirror command	Creates a volume mirror by using the two specified dynamic disks.
create volume raid command	Creates a RAID-5 volume using three or more specified dynamic disks.
create volume stripe command	Creates a striped volume using two or more specified dynamic disks.

Examples

You run these commands in the DiskPart interpreter. To start it, type diskpart at an elevated command prompt. Each example creates a 1000-megabyte (MB) object; omit the size parameter to use the remaining available space. For the full parameter list and behavior of each command, see the linked child article.

Before you create a partition, run list disk to identify the intended basic disk, then use the select disk command to give it focus. In the following example, replace <disk-number> with the number of the basic disk you want. To create a 1000-MB primary partition on the disk with focus:

select disk <disk-number>
create partition primary size=1000

Volume commands create volumes on dynamic disks that you specify by number. To create a 1000-MB simple volume on dynamic disk 1:

create volume simple size=1000 disk=1

To create a 1000-MB mirrored volume across dynamic disks 1 and 2:

create volume mirror size=1000 disk=1,2

To create a 1000-MB striped volume across dynamic disks 1 and 2:

create volume stripe size=1000 disk=1,2

To create a 1000-MB RAID-5 volume across dynamic disks 1, 2, and 3:

create volume raid size=1000 disk=1,2,3
