I recently purchased Goldstar M-2D 5.25 floppies to format and make duplicates of my ProDOS System Utilities disk that came with the Apple iic. When I attempted to format the Goldstar blank disk, I received this message on the screen ( see second pic). Then when I was attempting to duplicate the Apple Utilities Disk, I received this message on the screen ( see first pic). I tried different blank Goldstar floppies, but they all ended up with the same result. Are these Goldstar disks bad or is there another issue?
The Apple iic Utilities disk appears to be working fine. Any help would be greatly appreciated.
