[Your line eater is brok

	  A real quickie for someone who knows this off the top of
	their head:

	1)	Is the number of sectors/track for a hard disk
		a constant under DOS across all drives (or is it
		oblivious to such details)?

	2)	If number of sectors/track is different for different
		drive types, who maintains this information (the
		controller?) and how does DOS get access to this number?

	3)	If DOS expects a constant number of sectors/track, how
		do the RLL controllers (like Adaptec's) which increase
		storage by increasing the bit density per track get these
		extra bits back to DOS?

	And to respondents: thanks for saving me from having to look this
	up to satisfy my curiosity.
