Hi world,
	Does any body out there know :

	1)What is a "daizy chain" connection when connecting together drives?

	2)Why when two drives in a PC AT are connected together with a 34way
	  ribon cable to the disk-controler, part of the cable is twisted
	  between the two drives ? 
	  What's the idea about that ?
	  Which signals are exchanged ?
	
Thanks in advance.
