Hi, I'm trying to create a back up of an old 360 game using imgburn at 2.4x, Pioneer dvr-111d, and Verbatim DL. It's been a long time since I made backups, but im pretty sure I didnt miss a step...Now, at first I was getting a "Power Calibration Area Error" and unable to continue. I then updated the firmware from 1.26 to 1.29, but still the same issue. Then, I decided to open my PC and do some cleaning (blowing compressed air) and tightening the cable connections. Well, somehow after redoing the burn process, it worked until 30% progress and then I get the "Unable to Recover TOC" failure...I now have 5 coasters... :-( Any suggestions?? Thanks. by the way, works ok with non dual layer back ups.
