To add another idea to my previous reply, it should be pretty easy to test for
the presence of this particular problem by running your dd+md5sum test on just
the two physical disks which are plugged into that controller, starting the
tests simultaneously on both disks (in two terminal windows). See if you get
varying sums over several runs that way.
