  1. According to the following thread, the reason reading from multi-track discs is blocked is as follows: However, this check is implemented incorrectly -- instead of blocking multi-session discs, it blocks all multi-track discs, even when the disc holds only a single session. This design flaw has been in place since v2.5.6, released back in 2012. The fix was also hinted at in the same forum thread: Hardware DVD recorders finalize in a multi-track format even when they are used to record only a single session on a disc (generating a menu that is included even for the one session). Here is another example of the ImgBurn disc info box for this type of disc: PLDS DVD+-RW DH-16ACS JD11 (SATA) Current Profile: DVD-R Disc Information: Status: Complete State of Last Session: Complete Erasable: No Sessions: 1 Sectors: 1,949,584 Size: 3,992,748,032 bytes Time: 433:16:34 (MM:SS:FF) MID: MCC 02RG20 Supported Read Speeds: 2x, 4x, 6x, 8x, 12x, 16x Current Read Speed: 6x TOC Information: Session 1...

IsoBuster however supports them ! Due to my unfamiliarity with ImgBurn features, a visit to the forums was necessary to find other threads giving the work-around to add the DVD drive root in build mode. The error message currently reads: --------------------------- ImgBurn --------------------------- Sorry, using Read mode to create an image file from a multi-track DVD-R disc is not currently supported. Instead, use Build mode to create a new 'clean' image based on the contents of the disc. --------------------------- OK --------------------------- I propose changing this to act like the helpful auto-volume-label popup, offering to switch modes and add the source: Sorry, using Read mode to create an image file from a multi-track DVD-R disc could cause data loss. Would you like to use Build mode to create an image including only the most recent session?
