I have run "Initialization", downloaded and installed the firmware upgrade and attempted to setup RAID1 again and have run into the same issue. After just a few minutes of restructuring the array, I now have an E13 error (don't see that on KB#000002) and a message that a "RAID array error has occurred" and I am being instructed to restructure DISK 1 of my array.
I have done all of this before and I end up back in the same place.
I have now had this unit for several days and have not yet even started actually using it.
