The media I used was purchased at Costco: Imation/TDK DVD+R DL 8x Speed 8.5GB, media code RITEK (read using DVD Media Inspector).
Thanks. Ritek works good with Matshita drives. That's the only brand I never had a problem with.
My Late 2008 MBP has a MATSHITA DVD-R UJ-868 drive.
Same one in here.
Toast allowed me to burn at 4X, I think, as it took approximately 25 mins to burn about 8GB.
I got a Sonic Data DL disc to burn successfully last night. I rebooted the computer and opened Just Toast. I didn't do anything else while it was burning and it made it to the end. I had the speed set on Auto. It said average burn speed was 2x, but that it was burning a 3x. It took 24 minutes to complete.
Funny thing is though, the drive in my old MBP was almost totally silent during the whole burn. I even felt the computer to see if the optical drive was even running and could not feel any vibration. When I was burning the disc on the new MBP, I would hear the drive wind up and down at times, along with a steady humming of the drive motor. I'll have to try burning in the Finder next.
I am conducting another test using Disk Utility as we speak. I'll post the results as
Thanks.
