I'm trying to get a bootable external USB drive, from which to install Server 2008 R2, but all the online help I find includes a FORMAT comment in the DISKPART session. My diskpart displays a list of commands in response to the format command, i.e. there is no format command. Here is an example of the command sequence I'm trying to run on XP SP 3:
DISKPART> select disk 1
DISKPART> clean
DISKPART> create partition primary
DISKPART> select partition 1
DISKPART> active
DISKPART> format fs=fat32
DISKPART> assign
DISKPART> exit
