I was using scheduled downloads to move data from Volume_1 to Volume_2 as a means of backup. After upgrading to 1.06 this drive to drive copy now fails (red X indicator). What is interesting is that I can use scheduled downloads to copy files from a network computer to Volume_1 or to Volume_1, but not between Volume_1 and Volume_2. I originally adopted this approach as a workaround to RAID 1 for my 1.5TB drives. I got used to the copy method, and I liked the idea of having a backup so I would really like to get this working again.
BTW.. I reset the system to Factory Defaults after the firmware upgrade.
