DISKPART> help select volume
Selects the specified volume and shifts the focus to it.
Syntax: SELECT VOLUME={<N> | <D>}
VOLUME=<N> The number of the volume to receive the focus.
VOLUME=<D> The drive letter or mounted folder path of the volume
to receive the focus.
If no volume is specified, the select command lists the current volume with
focus. You can specify the volume by number, drive letter, or mounted folder
path. On a basic disk, selecting a volume also gives the corresponding
partition focus. You can view the numbers of all volumes on the computer by
using the list volume command.
Example:
SELECT VOLUME=1
SELECT VOLUME=C
SELECT VOLUME=C:\MountH
