I don't get it ... dd does not understand fs be it iso or else. It just copy the
medium bytes , the i/o error means that it cannot access the medium . Could you
try with the real device file (hdx or sdx) ?

>From memory i would tell that bs should be 512 (this depend on the driver which
sometimes have a 512 bytes jumper especially rw ones).
