[ snip long description ]

There is no difference between 68 pin drives and 80 pin drives as far as 
the controller and the drive are concerned.  It's all just a physical 
interconnect difference.  The problem you are describing is a 
non-functional SCA->wide adapter.  I have yet to ever find a simple 
wide<->SCA adapter that worked.  I've always had to have a real SCA 
backplane before things worked properly.
