What exactly do you mean by an "image" disc. There are discs made using the Nero Backitup ImageTool for restoring a backup. Also, if you made a SecurDisc which is password protected, no one can help you because they would need to know the password.
I'm a little confused as to why you would need "file name and date". If you open the disc in Windows Explorer, is there a .nco, .nda or .nba file on it? Is something asking you for a file name and date?
