Diskpart

DiskPart

DiskPart.exe is a text-mode command interpreter that enables you to manage objects (disks, partitions, or volumes) by using scripts or direct input from a command prompt. Before you can use DiskPart.exe commands on a disk, partition, or volume, you must first list and then select the object to give it focus. When an object has focus, any DiskPart.exe commands that you type act on that object.

DiskPart scripting

Using DiskPart, you can create scripts to automate disk-related tasks, such as creating volumes or converting disks to dynamic. Scripting these tasks is useful if you are deploying Windows by using Unattended Setup or Sysprep, which do not support creating volumes other than the boot volume

To start a DiskPart script, at the command prompt, type:

DiskPart /S scriptname.txt

Where scriptname.txt is the name of the text file that contains your script.

A sample script to create single NTFS primary partition with label as "windows",with drive letter as "C"

select disk 0
clean
create partition primary
select partition 1
format fs=ntfs label="windows" quick
assign letter=c
active
exit

The following table lists the DiskPart error codes:
