I have an external USB hard drive with all my music on it. I recently moved to a new(er) computer. Now I cannot play any files. I get an errpr message: "You do not have permission to open this file." The security settings for the file give full control to "Administrators (ComputerName\Administrators)". I am logged on as Administrator. I went through the process with Windows to take ownership, but,,,, This is a stand alone local machine. When I look at the settings for the hard drive and look to add permissions, when I enter "owner" it shows a name "Ron" which is not me and has nothing to do with me. It says it is in a folder "(ComputerName)" Where is that folder with "Users, Groups, or Built-in security principals?" Any other helpful suggestions?
