I have a .mdf/.mds file that requires burning to a DL DVD. I first tried burning it with Alcohol 120% but got a failure notice at the 50% completion level which leads me to believe it failed to transition the the second layer. I then installed ImgBurn and tried it. After 1 hour 26 min. of hard drive thrashing and occasional DVD drive spinning, I got this failure: Set L0 Data Zone Capacity Failed! - Reason: Power Calibration Area Is Full I Googled for that and most of the answers involved imapi which Win 7 doesn't use or firmware updates. Since I can't find any place on Liteon's Website to download anything, I can't do that either. I tried burning a single layer CD-RW with ImgBurn and it worked fine. I have also tried both of my identical burners which are supposedly DVD+RW DL capable and am using Memorex disks. Does anyone have any other ideas? Would it work to just extract the files from the .mdf using 7zip and just burn those files to disk?
