First DL Data DVD

[Rincewind]

So I decided to burn a data DL-DVD, bunch of rar/7z files up to 8.3GiB total. Everything went fine, burned and verified successfully. Still there is one thing that I am wondering about:

I 18:54:49 Optimal L0 Data Zone Method: ECC Block Boundary

 

Since this is not a DVD-Video disc, how does ECC boundary work? When the data was allocated to each layer, was the data truncated (split)?

 

I often wonder about this, since I am always unsure of making a DATA DVD that is filled with media (MP3/FLAC) which file would be 'split' and have a potential pause when going from L0 to L1.

An ECC block is just 16 sectors on a disc.

 

The number of sectors in the first layer must be a multiple of 16 (the ECC block size) - or the drive makes it so anyway.
