I am cognant of the problem and huge consequences here, and I agree that Dlink should do something about it. Implementing a few extra safeguards in the firmware can be simply done, as long as Dlink support gives a d$%^. But in the meanwhile, just to make sure we can formulate a "best practices" approach: Was the "new" drive you added totally brand new with no pre-existing partitions, files, etc on it?
