subst is used to create virtual partitions; it can't really partition a hard disk.

Command: subst Function: associates a path with a drive letter. Format: SUBST [drive1: [drive2:]path] SUBST drive1: /D Explanation: drive1: specifies the virtual drive to which you want to assign a path. [drive2:]path specifies the physical drive and the path to assign to the virtual drive. /D deletes the substituted (virtual) drive. If you type SUBST without any parameters, it displays a list of the current virtual drives. —quoted from the CMD help document
