I am not sure what dd_rescue is likely to do with option arguments out of place.
I would be inclined to start again with a syntactically correct command and
make sure there are no errors...
If you have to leave it as is, you could check that the log file is
also growing.
You could also unzip the start of the image and check that it holds valid
filesystem headers.
