Did the dd runs with short "ls -l" result tell the "isosize"
result, nevertheless ?

Command interpretation is supposed to depend on the
shell interpreter (e.g. bash, dash, ksh) and not on the
terminal emulator (e.g. xterm, gnome-terminal, Konsole).

On the first hand we have to concentrate on the messages
from the dd runs which deliver too few bytes in the .iso
files.
After a dd run turned out to copy not enough bytes, look
into the system log whether any error message about "sr0"
has been freshly recorded.

But why did the retry succeed ?

Richard: Did you copy to a different directory ?

We fiercely deny any similarity with said systems.
No bugs shared.


Have a nice day :)
