DiskPart commands help you to manage your PC's drives (disks, partitions, volumes, or virtual hard disks). Before you can use DiskPart commands, you must first list, and then select an object to give it focus. When an object has focus, any DiskPart commands that you type will act on that object.
You can list the available objects and determine an object's number or drive letter by using the list disk, list volume, list partition, and list vdisk commands. The list disk, list vdisk and list volume commands display all disks and volumes on the computer. However, the list partition command only displays partitions on the disk that has focus. When you use the list commands, an asterisk (*) appears next to the object with focus.
When you select an object, the focus remains on that object until you select a different object. For example, if the focus is set on disk 0 and you select volume 8 on disk 2, the focus shifts from disk 0 to disk 2, volume 8. Some commands automatically change the focus. For example, when you create a new partition, the focus automatically switches to the new partition.
You can only give focus to a partition on the selected disk. When a partition has focus, the related volume (if any) also has focus. When a volume has focus, the related disk and partition also have focus if the volume maps to a single specific partition. If this is not the case, focus on the disk and partition is lost.
