As I suspected, the kernel stopped reporting the size of /dev/sdb, and 
ddrescue is using the maximum size (9223 PB). You will need to 
power-cycle /dev/sdb, reboot, or provide ddrescue the right size with 
the '-s' option. (And maybe use the '--complete-only' option in 
subsequent runs).

Ddrescue 1.17 treats this case specially bad because of the way it marks 
failed blocks. Maybe you could update to a newer version.
