What is the filesystem in your destination drive (/media/recoverydrive)?

sudo ddrescue -vn -i0 -o0 /dev/sdb /media/recoverydrive/01.img 
/media/recoverydrive/01.log
sudo ddrescue -vn -i50GiB -o0 /dev/sdb /media/recoverydrive/02.img 
/media/recoverydrive/02.log
sudo ddrescue -vn -i100GiB -o0 /dev/sdb /media/recoverydrive/03.img 
/media/recoverydrive/03.log
etc...
