If your startup disk is nearly full, try to free up space on it.

Quit all open applications you’re not using. Use blank discs that are rated for the burn speed of your drive, or consider using a different brand of disc (excessively cheap or off-brand optical disks are known to have problems). Wipe the shiny surface with a soft, damp cloth, working from center to edge.ĭo not move, bump, or shake the computer while the disc is being burned. (try 1/2 that maximum speed )īE sure the disc is clean.
