It sounds like the problem which used to occur on the Master computers - they had the 1772 controller like the arc - and there is the slowest step time of 12ms - I do seem to remember a version of the DFS which was suppost to cure it - but I think the chances of finding such a piece of software are remote. I know about this problem because we tried to get our old 5.25" drives going with our master when we got it a few years ago - we ended up buying faster drives!
