I am struggling with the same issue with respect to security and want to operate the MyCloud on a LAN with three computers doing backups and file sharing. Each computer has a different primary user who has independent access to the MyCloud and I do not want the SmartWare share, the backup target, to be open to the public. Can MyCloud not operate that way? The documentation is thin.
In SmartWare 2.4.2 the Manage Drive Security option under Manage and Customize button in Help says to click the Settings tab and Set Up Drive to display the drive settings screen. There is no Set Up Drive button in the Settings tab for SmartWare 2.4.2. Also, there is no “Managing your Personal Cloud Users” in Help in the Dashboard. In any event, I cannot find those things. The User Manual for SmartWare 2.0 has not been any help in this area.
