Unfortunately, I always having trouble burning 50GB BR discs, and I would understand if the problem is the bluray burner or the optical discs.
I have Win 7 x64, 8gb Ram and a radeon hd6970. I have a Gigabyte GA-990FXA-UD7 motherboard. This board has 6 ports SATA6GB controlled by an AMD chip and 2 ports SATA6GB controlled by a Marvell chip. My blu-ray burner and my DVD burner using the two ports controlled by the Marvell chip. BluRay burner is an LG BH10LS38 and I use Verbatim BD-R DL Printable (ImgBurn shows "VERBAT-IMd-000"). The problem occurs burning ISO file and also burning BDMV-CERTIFICATE folders. The problem occurs burning at 2x and also at 4x.
The problems are 2:
- Sometimes the problem occurs at the beginning, when ImgBurn shows the message "reserving tracks". In this case I hear the writer who works endlessly and the copy process never starts. After a few minutes I have to finish the process manually.
- Other times, as it begins the copy process, ImgBurn shows the error "Failed to Write Sectors 0 to 31 - Reason: Program Memory Area Update Failure". Then, ImgBurn try again and seems to have success but when the copy process finishes it gives me the error "Finalise Disc Failed! - Reason: Can not Write Medium - Incompatible Format".
If I use the same media (but in the cut of 25GB), the problems do not occur. Please help me to understand where is the problem. I think it's the fault of Verbatim's BluRay but I always used Verbatim (also for DVDs and also i DL format) and I never had problems.
