To answer your question, we CyberLink use the Format Unit command but we don't use the Format Type 00h on DVD-RW (SL/DL) disc. FYR.

I would like to write my comment one by one. [Answer to question] Mt.Fuji group did not discuss the change of the DVD-RW SL (Single Layer) Format Unit Command. There is no change in other media types (DVD-RAM, +RW, etc.) RW-DL is new media. So I think Pioneer proposal does not change of the drive behavior. [Comment as a chair] I understand that you do not desire the device behavior which cannot be checked. [Comment as Pioneer] We need to focus the behavior of the default type (Formatting on Format Type = 00h). Full format of the DVD-RW DL will take more than 1 hour. User never accept this long time. The other hands, 2 hours - 6 hours TV recording on the RW-DL disc may fill the disc up. Once it becomes ROM compatible state (Complete state), another full format is not necessary. For example, BD-RE drive dose not fill data area up with null data of the RE disc by the default format operation. Drive changes Defect List only. If there was no linear replacement (no defect), host can read user data on the RE disc before file system re-construction. Usually file system re-construction makes the old user data unreadable. [Question to software venders] The RW-DL physical format allows pre-formatted media by the media manufacture. If software does not use the Format Unit command Format Type = 00h, we can stop this discussion now. All software venders, how do you think? Does the software use Format Unit command?

We checked this issue at Microsoft optical platform storage and core file system services. Most important is we do not want to change existing format code behavior. Per consistency with DVD-RW SL, existing format code behavior shall be unchanged. Otherwise it would cause unexpected behavior in our software. If new format behavior is desired, it needs to be with a new format code or option. Also, we do not want vendor specific implementations. If there is a feature, please make it mandatory. If it is not possible, at least specify the feature *and the feature availability recognition*. Please let us know if further clarification is needed.
