Check your old technotes. I think this was not only covered there, but
there was a free controller board upgrade at one time and I seem to recall
it was to fix this type of problem. What I don't remember is if it was
for the Apple 3.5 or Unidisk 3.5. 

I have two of the older disk ][ drives (with the 20 pin connectors)
connected to my 3.5 and have no such problems..
