Is this a question or a report of an observed fact ?

If it is an observation, then i would be strongly interested in seeing the
results of two runs of

  STICK=/dev/sdc
  xorriso -indev stdio:"$STICK" -report_system_area plain

with STICK holding the device address which you used with dd.

Each run will emit about 50 lines of text.
You may catch them in a /tmp file by

  xorriso -indev stdio:"$STICK" -report_system_area plain 2>&1 | \
    tee -i -a /tmp/report_system_area.txt

Please make one run after freshly writing the unmodified ISO to the stick
before you use gnome disks. Afterwards make a second run to show the result
of gnome disk's activities.

Have a nice day :)
