"HL-DT-ST DVDRW GSA-S10N" is being shown by system profiler. No brand name is given. I've tried 4 different media, Memorex, TDK, Phillips, Fuji. The last 7!! disks DVD-R have failed regardless if they're either phillips or TDK. "The drive reported an error: Sense Key = MEDIUM ERROR Sense Code = 0x0C WRITE ERROR" This happens as the lead-in is being written; almost immediately after the burn button is pressed. (usually the error pops up about 10 seconds, so before actual data is burned to the disk), fails to lead-in. Using toast 8.0.3, + 10.5.2 latest apple software updates as of today. I am aware that people often recommend to try various media/burner combinations to find something that works, with my success so far, I'd venture to guess it goes beyond that. This is horrible. At first I also suspected media, but now i'm having my doubts. Anyone else having problems with the new MBPs? I have a 15" 2.5 MBP w/512MB 8600GT, 4GB RAM, 250HD The disks make a noise when they spin up and it doesn't sound normal, judging by my past experience with several macs. Almost sounds like its spinning too fast or something. odd. Note, I haven't had any problems reading disks so far. Thanks & Cheers. Looking forward to hearing from new owners!
