Hmm, not sure that worked the right way:

GNU ddrescue 1.18-pre7
rescued:     1764 GB,  errsize:   8111 MB,  errors:   87250
Current status
rescued:     1768 GB,  errsize:   8131 MB,  current rate:        0 B/s

   opos:   791401 MB, run time:   16.09 h,  successful read:    4.06 m ago
^C

$ sudo ddrescue -f -n -d -O -s 512 /dev/sdf /dev/sde logfile

GNU ddrescue 1.18-pre7
rescued:       512 B,  errsize:       0 B,  errors:       0
Current status
rescued:       512 B,  errsize:       0 B,  current rate:        0 B/s
   ipos:         0 B,   errors:       0,    average rate:        0 B/s
   opos:         0 B, run time:       0 s,  successful read:       0 s ago
Finished

$ sudo ddrescue -f -n -d -O -R /dev/sdf /dev/sde logfile
