fdisk (create partition)

help fdisk
says I can use the -m option to create partitions, but I was not able to use it correctly.
I tried :
fdisk -m 0 hda
to create the first partiotion on ide 0:0.
But I got an Exception because partiotion 0 (or device hda0) did not exist.
Before that I used
to create / initialize the mbr.

any suggestions ?
