I have 1 of my drives have failed but it also seems as the slot has failed.  I replaced the drive with a new one and all I get is quick amber light flashing.  I tried 2 new drive3s and the same thing.  If I move the old drive to a new slot the drive goes to ready and it seems I can use it.   My Question - Can I move my RAID 1 from drive 4 and 5 to drive 5 and 6 and leave slot 3 empty.  I have the drive in there (slot 6) and I have a steady green light but I do not know how to have my RAID 1 go to that drive (slot 6) instead of drive (slot 3).  Thanks for your help.
