The drives are Hitachi 500 GB 7200 RPM 16meg:

HDS725050KLA360

Adaptec told me today that these drives are verified or approved or
something with that card...

So in your case, you made multiple arrays with those drives, and then
large data moves between arrays caused crashes, and it turned out to be
the drives fault ?  I would think the problem you describe would manifest
itself locally to a single array ...
