Ah, Thomas, you're the fairy :-)

My wish of someone chiming in became true

Yes, option -p makes a lot of sense.

As far as I understood, Richard is already doing that: his "big" disk
(where the backup is going to) has already a file system and is mounted.
His "first cut" command

     ddrescue /dev/sdc /mnt/repaired.img /mnt/repaired.log

is already copying the raw device /dev/sdc to a file in the target
system.
