I recently bought the My Cloud Home and I must say I am impressed. Only issue I am facing where I need your guidance is - I connected a 4 TB portable HDD to My Cloud and when I gave access to other users I found they can create and delete folders in my extended/external drive. This is concerning as I wanted them have only read-only access not Full Access. The My Cloud UI gives me option to change share rights only on MyCloud drive but not on extended drive. No options appear for extended drive. Since rights management is UI based I assume there will be way to control access rights on external drives too? Please guide.
