I gust received my LG BH08LS20. I had it to replace my Pioneer BDR203 that would not burn TDK BD-RE 50 and would not read back some of the disks it has written. I first tested LG on all my burned BD and it has recognised them all from first attempt (Very nice!) I even managed to burn TDK BD-RE 50 successfully. This drive offers 2X, 4X, 6X recording speed for my TDK BD-R that my Pioneer would only write at 2X.
BUT. When I burned few TDK BD-R when I look at the disk surface it looks like it was using Z-CLV. I can see circles on the disk where supposedly drive has changed recording speed. I thought it was probably due to me over speeding disk to 4X. I have changed speed to 2X it looked a bit better but I still could see circlesâ€¦ For some reasons some disk it has burned will have few zones when one particular had about 7 zones! I looked at my disks written with Pioneer and they all look nice and even on the same media. My disks looks similar to the photo here but some of them have lot more zones.
I had bad experience with DVD media burned with zone they would not all drives will be able to copy disk and stuck on the speed change point.
DVDinfo pro shows media rated speed 2X and Available speed 2X CLV, 4X CLV and 6X CLV.
I could not understand why recorded disks look like Z-CLV. During the write I did not noticed drive changing speed it would accelerate in the first few minutes to 4X or 2X (Depending on chosen recording speed) and stay there during the process. Buffers do not seem to struggle.
Could you guys please examine closely what does your recorded disks surface looks like? I am just wondering could it be faulty drive or is quite normal for this model?
When I received it I have noticed some scratches on the bottom of the drive so it has probably been in another systemâ€¦
