I have an external drive mounted via firewire and formatted with HFS. I would like this drive to be accessible by an administrator, say admin, only and have used Finder to set permissions. So the user and group for the /Volume/<drive> is admin:admin. I have created a standard user, say user. However I find that when the standard user logs in he can access the volume and the rights for the drive become user:user instead of admin:admin, so that drive is accessible by any login user no matter what permissions I set as an administrator. How can this be solved? Thanks in advance for any help.
