I meant a pass separate from the rescue. That is, if you use the --fill 
option, ddrescue does not rescue anything. It only fills the error areas 
described in the logfile. I think it is the best way to be sure that 
every bad sector is filled.

With the on-the-fly method, once you have rescued part of the file 
without the fill option there is no way to fill the bad sectors so 
rescued, unless you overwrite them every retry, what is not very efficient.
