RE: Defragging Win NT

Doug,
	Why do you make the swap file partition the last partion.  Isn't the first
partition the one closest to the spindle (i.e smallest radius) therefore
offering the fastest access?  Am I mistaken or are there other overiding
reasons for making it the last partition?

Thanks,

Mark
