Trouble burning disks: Error Code 0x80020063. iMac

After several hours of research, Genius Bar visits and phone calls to Apple Care, I finally got my issue escalated to the engineering level at Apple. I was impressed that I received a personal telephone call with the following explanation. Kudos to Apple for the follow-up!

I am not a very savy computer person and will probably use the incorrect, exact vocabulary and processes but here goes a consumer-level explanation of why, when trying to burn more than 1 dvd or cd disc using Finder of the exact same media, that you would receive:

1. Substandard blank media from certain vendors. I don't think this is at all the problem because I tried 6 different brands and got the same result.

2. Evidently, when you put in a blank disc and drag the files you want to burn into the "...fbbf" folder, Finder links back to the orginial media using "alias links". Finder does not create a "temp file" like Toast or other programs might do. When the first burn happens, the processor "reports back to the program" that an event has occured (called a "ckecksum" that changes "permissions"). Even though the media has not been altered, but because it has been burned once, the computer thinks that the media isn't exactly the same as its orginal and, therefore, calls your attention to that fact with the error message above.

3. The tech, John, explained that several of his fellow engineers are aware of this situation and he is moving the case up his internal chain of command.

4. As of now, to "fix the problem", according to him, is difficult because of the uniqueness of each individual burn and there is no patch pr downloadable repair in the works for now.

5. Low tech fix = take the disc completely out of the drive, delete the error message(s), reinsert the dic and the burn should be successful. Then start over from scratch to burn other discs one at a time.

Hope this helps.
