Ok, that was for lack of a better title. Anyway, Steve, my company produces a line of storage equipment which uses various disk drives, etc. When changing a component as major as the drive in the system, we evaluate the risks involved and usually end up testing the entire system again fro emissions and immunity. If the system in question is a system with drives that are faster than those last tested in the system, or if there is a major difference in the PCB layout of the drives, there is no weighing of risks; we test the entire system again.
Of course, those are my views regarding testing approved systems with new drives. Your customer may have a different view. Steve Chin StreamLogic Corp.
