Been trying to burn a .dmg image to a cd-r, but disk utility is causing me problems. The image is 535MB, and I am using a 700MB blank cd-r. Each time I try and burn it, I keep getting the message that the cd does not have enough space. I have tried it with different blank cd's but no luck. Burning a 230MB image was fine, but this one is causing me difficulties, am i missing something here? any help please?
