why can i not have one partition
trying to install xp pro on to a new wd500 harddrive. when the pc boots from the cd and looks at the drive it can only see 127.99g so i installed xp and then it lets me format the other 340g (give or take a few g's). which is no good as i dont want the drive split. is there any way to install on to the drive to give me the 500g partition.
