	One month ago, Claus Brod has posted in comp.sys.atari.st an article about
adding a new drive in the megafile 30. I'd like to add another drive but
I have several problems about drive compatibility.

	o if the new drive has not the same capacity (30Mb), suppose
	20Mb, how does the driver (basically the i8085) recognize the new
	size? (recognition of # of heads, # of cylinders ?)

	o if the new disk seek-rate is different (prefer faster), will
	this new seek-rate be recognized (without any effect on old disk)?

	o I have noticed in my megafile30 that there is a 16 pins
	connector with a full line (8pins) connected to ground and the
	others connected to the i8156 (2 // ports + timer). (near the 64K
	eprom). I beleive that this is supposed to be used as a configuration
	connector, plugging small straps between ground and i8156 line,
	but how and what for? 

	o About software, I don't care since I always use Minix.
	(but i beleive that my old AHDI program will not be able to
	recognize a new disk)


Thanks for answering me...
