hello

i have installed windows xp coporate edition (sp2) serval minutes ago.
my attention was to format my computer but for some reason the format option doesnt appears during the installation. i also try to repartition my drives but it didnt allow me to. so i continued installing.
I got 2 drives on 1 hardisk: D and C. i installed my windows on D. after i formated it trought the windows.(at the first time i installed my windows on C but since it didnt format i formated D trought windows and installed windows on it.)
Now i try to format C: trought windows and after it finishes formating it shows me an error: Windows was unable to complete the format.
I also tried to format trought Start->Run->command->format C: and it shows me the same error.
what can causes it and how can i format C:?
few notes:
*Sorry for my english im not even sure it still sux
*I'm sure I'm not trying to format while running operating system/programs from C:.
