The third is different. I'm now in day 3 and have rescued 2471MB. I
don't know how much data is on the disk: ddrescue went for all 4GB+ but
I suspect that some sectors are missing at the start such that the size
is unknown. Which driver/layer/device is responsible for determining
size of tha DVD?
If the filesystem is ISO-9660 you could try isoinfo tool which is part
of genisoimage.
isoinfo -d -i /dev/cdrom
It should list the block size and the number of blocks among other
information from the primary volume descriptor of the filesystem
if its available.
