No. partition0 is a symlink pointing to DR0, which in turn is the
entire physical disk. As admin:
$ ls -l /proc/sys/Device/Harddisk0 | grep DR0
brwxrwx--x 1 Administrators SYSTEM 0, 250 Nov 11 17:32 DR0
lr--r--r-- 1 Administrators SYSTEM 0 Nov 11 17:32 Partition0 -> /proc/sys/Device/Harddisk0/DR0
$ ls -l /proc/sys/GLOBAL\?\? | grep DR0
lr--r--r-- 1 Administrators SYSTEM 0 Nov 11 17:32 Disk{2b5b33fa-7185-944d-98ae-4ff14c0e5391} -> /proc/sys/Device/Harddisk0/DR0
lr--r--r-- 1 Administrators SYSTEM 0 Nov 11 17:32 PhysicalDrive0 -> /proc/sys/Device/Harddisk0/DR0
So the real partitioning starts with partition1, since partition0 is a
link to the physical disk as a whole.
