The Quantum Atlas III evidently has an identical problem to the Atlas II.

Browse Source 
It keeps returning queue full until we have reduced the number of tagged
openings to the minimum.

So, put in a quirk entry with the same work-around.  This quirk entry is
only for the 9G Atlas III, once someone comes up with inquiry information
for the 18G version of that drive, we can quirk it as well.
