Your syntax does not seem correct, I think this command would image sdb to
/storage and save a log file to test.bin you it may be a transcription typo,
and you could try copying the good areas first.
sudo ddrescue -v /dev/sdb /storage test.bin testlog
suggestion:
copy the error free areas first
ddrescue -n /dev/sdb /storage/test.bin testlog
attempt to recover any bad sectors
ddrescue -r 1 /dev/sdb /storage/test.bin testlog
