No, you don't. :-)

`-C'
`--complete-only'
     Limit rescue domain to the blocks listed in the logfile. Do not
     read new data beyond logfile limits. This is useful when reading
     from devices of undefined size, like raw devices.


"The blocks listed in the logfile" are not only those already rescued, 
but also those non-tried, non-trimmed, etc. Look at the end of the 
logfile and you will probably find a very big non-tried block.

If you want to limit the rescue to the area currently rescued, try the 
option --max-size like this:

  $ ddrescue --max-size=211755MB /dev/sdc /dev/null rescue.log
