 Roy, we tried. Several phone calls were placed to you and none returned. 
Between SCO and Micropolis there was "well, it should work" but we could not 
get any help from Adaptec to make it work. 

In the meantime, when time is of essence, one has to look for other 
alternatives. The advice from technical support at Adaptec was to try a 
variety of other things, but disabling the cache (I guess that is the 
read-ahead) was not mentioned. After several days of format attempts it 
becomes cheaper to go to another vendor that guarantees his controller to work 
and offers more documentation than the meager handout from Adaptec.

Even to this day, no one on the net has that drive with that controller 
working. At least no one has come forward. Some SCSI controllers, yes. Other 
drives, yes. Even lots of smaller 330MB drives. 

I suppose the old lesson about never assuming anything to work until proven 
otherwise has stood the test of time again.

One of these days when we have more time, we'll give it another shot.
