SCSI errors on DVD+R
Redumper seems to have trouble with this DVD+R. By the looks I would think that it is a burned as opposed to a pressed disc. It is from a rather small Kickstarter campaign.
It just keeps going and going. The eventually produced ISO has the correct content though, even when I aborted the run. So this seems to be in the sectors beyond the meaningful data.
From sector 703040 onward:
[sector: 703040] SCSI error (SC: CHECK CONDITION, SK: ILLEGAL REQUEST, ASC: ILLEGAL MODE FOR THIS TRACK)
DiscImageCreator processes the disc like any other, without such an inflated processing time.

There is:
warning: READ_CAPACITY / PHYSICAL sectors count mismatch, using PHYSICAL
Physical sectors count currently takes priority, if it's incorrect yeah it will overread. Don't see an immediate solution here, if DIC works it means that it takes sectors count using GetCapacity SCSI call, but prioritizing that will kill KREON compatibility (GetCapacity on KREON returns 0 sectors). Not sure what's the clean way here.
Well, I'm not sure what the appropriate solution would be. But since KREON drives seem to be a very special case here, I would probably add a special case for those to the program.
Then again, there might be a reason I'm not aware of (apart from cleanliness) to not do that. I also don't know how often and for which drives those mismatches occur and which change would therefore make the most sense.
I'll keep this open for now, will do some experimenting when working on other DVD features.
I do have a similar error (SCSI error (SC: CHECK CONDITION, SK: ILLEGAL REQUEST, ASC: LOGICAL BLOCK ADDRESS OUT OF RANGE)) occuring on a DVD-RAM. Interestingly, the disc doesn't even has a file system, and yet Redumper dumps every sector it can acces. Now I wonder, if one can use Redumper to find files on a previously deleted rewritable disc. Or if this was just something with the DVD-RAM.
