thefinalprophecy Posted June 25, 2007 Share Posted June 25, 2007 I have downloaded several disc images in .dmg format, most of which require dual layer discs. what is the best way to burn these? OS X Disk Utility kept on giving me a "laser calibration error" (only for the dual layer discs, not single layer). I am using a SATA Lite-ON DVD-RW drive that I just bought a month ago. A buddy of mine told me that he thinks that OS X will only burn dual layer discs to official macintosh dvd-rw drives. Would it then be possible to buy that Pioneer drive (can't remember the model number... anyone?) and use that instead of my Lite-On? I have also tried using MacDrive 7 on my Vista installation, but that program would barely function at all. it DID allow me to see the contents of my Mac partition, but the function that i really wanted--Burn a Mac CD or DVD--would not even start! The third solution that I heard about was using Disk Utility to convert the .DMG to .CDR, transfer the .CDR images to a Windows partition, and rename the extension to .ISO and burn (simply). However, some people reported that this did not yield a readable DVD on OS X, and i do NOT want to waste precious expensive DVD-R DLs if I can avoid it. It is also very very time consuming to convert the 7 GB images, but I will just do it if it'll work. Thanks.

whocares Posted June 25, 2007 Share Posted June 25, 2007 Works fine for me. I just use Disk Utility and select the "Burn Image". I did this exactly yesterday with a 6.07GB .dmg. I would guess that there is something wrong with your drive perhaps.

thefinalprophecy Posted June 25, 2007 Author Share Posted June 25, 2007 what model is your drive?

sarahbau Posted June 25, 2007 Share Posted June 25, 2007 You mentioned that you're using DVD-R DL. Have you tried with DVD+R DL? What does Apple System Profiler say in the "Disc Burning" section? I know that my drive supports DVD-R DL, but ASP says only DVD+R DL, while Toast 8 says both.

thefinalprophecy Posted June 26, 2007 Author Share Posted June 26, 2007 they are actually +R DL, not -R. I'll have to check on the other part once i restart into osx.

thefinalprophecy Posted June 28, 2007 Author Share Posted June 28, 2007 Yes, I can confirm that my drive supports +R DL. Tried it on a 2nd drive too (via) USB and same problem.

josh256 Posted June 28, 2007 Share Posted June 28, 2007 Yeah.. only thing you can't do within any OSX/GUI-based burning tool is specify the layer-break offset when burning a DL image.... which is generally irrelevant unless you need to burn xbox 360 ISO (backup of course) -R DL aren't read by many consumer devices btw (DVD set-top, xbox360, etc) Link to comment https://www.insanelymac.com/forum/topic/55292-burn-a-dmg-file-to-a-dual-layer-dvd-r/#findComment-396797 Share on other sites More sharing options...
thefinalprophecy Posted June 30, 2007 Author Share Posted June 30, 2007 I don't know but this is pissing me off. I need to get 52gb off this drive.
