You are welcome. :-)

Thanks for reporting this. You are right that ddrescue incorrectly warns 
about the "-D, --synchronous" option being ignored in fill mode. It is 
in fact functional in fill mode.

Surely my fault, but you have seriously misunderstood what fill mode 
does. I'll try to explain it better in the manual. Thanks.

Fill mode is intended to fill disk sectors with a pattern usually 
smaller than the size of a sector, say all zeros or repetitions of the 
string "BAD SECTOR ".

If you want to write the image back to the original disk all you have to 
do is to swap the input and output file names and use a new logfile (or 
no logfile at all).


Best regards,
Antonio.
