Well I managed to get a workaround for the Volume ID, but now I've run into another problem. I am trying to full format some BD-RE disks and imgburn hangs my PC at 99%, I left it for 8 hours on 99% and it didn't get any further, I had to physically shut down the PC. Odd thing is I have tried the same with Power2Go 7 and it completes the (full) format in about 40 minutes. Firstly I thought it might be my drive, but imgburn does the same on another PC with a BD drive. I have read the double layer FAQs (although these are single layer 2.3x BD-REs) and am not sure that the BD-REs I am using are any good, they are shown in Imgburn as CMCMAG V3 2.3x, I have successfully erased a disk using p2g7 then used imgburn to burn data to it and the verify completed successfully and they work in 4 different BD drives, anybody have any thoughts? Should I just bin the disks or is there something I am missing in Imgburn which would explain this?
