You are attempting to write the image (and log) directly to the disk device, instead of a path on the filesystem. You should use something like this (which would put it in your home folder).

sudo ddrescue -r 3 /dev/sdc /home/yinon/ImageFileName.img /home/yinon/TextFileName.txt

If you are doing this from a Live CD, you will need to mount a hard drive prior to running ddrescue and change the output to point to the mounted filesystem. For example, if you wanted to back up the image to sda6, enter the following from a terminal:

sudo mkdir /media/backup

sudo mount /dev/sda6 /media/backup

You are creating the folder /media/backup, which is where we are mounting the drive.

You can also just click on the drive that you want to back up TO in Nautilus (the file manager) and it should automatically mount it. If you hover over it, it should show the full path to it, it should be something like /media/LABEL, where label is the label of your drive.

Your ddrescue command then would look something like this:

sudo ddrescue -r 3 /dev/sdc /media/backup/ImageFileName.img /media/backup/TextFileName.txt
