I just upgraded from a Gen 2 to a 5C, while I was at work. In transporting the drive back home, one of the drives came slightly unseated. When I turned it on, it went into data protection mode, which continued after seating the drives when I noticed like 30sec later.
I had just received delivery of a new 6TB drive to add to the 5th slot, and had intended to do so before this happened. Is it safe to add the drive now so that I can get all this data protection stuff done in one swell foop, or do I really have to wait for this to finish and then do it all over again when I add the new drive?
