But you never get the desired data in the required form ;/
I'll restate my environment and goals.

ENVIRONMENT:
    I have a stack of purchased Debian distribution DVDs 
{Squeeze, Wheezy, & Jessie}.
    [Internet capable of downloading ISOs being *NON*existent]

GOALS:
    To have the ability to install multiple configurations of 
multiple versions
    of Debian on multiple widely separated machines with no 
networking capability
    [i.e. sneaker net].

METHODOLOGY:
    Copy all DVDs to ISO 9660 conforming files [dd understood to 
be correct tool].
    Copy the resulting files to USB device for convenient loop 
mounting.
    As loop mounting 13 (or more) files can be cumbersome, use 
xorriso to process
    *.iso to obtain complete repository on a single USB device.

Hi,

dd, libc, the kernel or whatever on your system seems to have
a bug with readable size of DVDs. This size seems not to change
when a new DVD is loaded into the drive.

Nevertheless, /sys indicates that the correct size is perceived
by the kernel at least in some of its parts. So there is some
hope that libburn (via xorriso) and the drive could team up
to retrieve all data from the DVD.

See my proposal 

  xorriso -indev /dev/sr0 \
          -check_media data_to="$FILENAME" --

in
  https://lists.debian.org/debian-user/2015/09/msg00890.html

xorriso may also extract the files directly from DVD:

  xorriso -osirrox on:auto_chmod_on -overwrite nondir \
          -indev /dev/sr0 \
          -extract /pool /media/richard/REPO8/test/pool

This will use SG_IO for communication with the drive,
like above -check_media proposal.

It would be interesting to see what happens when the ISO 9660
filesystem driver tries to read blocks which read(2) is not
willing to read. I.e. the way of "mount" and "cp".


Have a nice day :)

Thomas
