I have an Admin Account with 2 external drives used for backups. There is a second "User" account that is prohibited from access to the external drives. But, what I want to do is to simply not show the external drives at all - either in the Finder side-window or on the desktop. They would remain as not read or write access of "user" not Admin account. The drives show now but with a folder icon (not a drive icon) and with some kind of little red symbol on the bottom left sign that means access is not allowed.
How can I simply hide the drive icons from appearing at all in the non-admin user account? Oh yes, and 1 more constraint please - Sorry but no terminal commands. (If I don't understand it then I should not do it.)
If I understand correctly, you do not want to have any of the external drives showing? If that is correct, go to Finder Preferences and uncheck "external disks" under General, and then under Sidebar, uncheck them there as well.
