	The WD1002 WA2 controller is physically restricted to 1024 cyls.
	The WD1003 and newer ones are limited to 2048 :-)

>I had a similar problem with Maxtor 1140 drives, which are 917 cylinders,

	But, the 1140 is *really* 1220 cyls, the label (and testing) is
the only difference between it and the 2190.  Try the same formatting
trick for 1024 cyls (or 1220 if your controller can grok it) ... :-)
I did this to 3 of them - they are still alive and kicking !

(Microport's V/386 2.2 and before have a hd driver that is limited to
1024 cyls; version 3.0 (shipping in Sept) handles up to 2048+RLL+ESDI)
