True.

It could, but this would have some drawbacks:

- It complicates the code because there is no such thing as an 
"already-known-good-block"; any block succesfully read in a previous run 
may be unreadable now.
- Data consistency can't be verified unless the data is also read from 
outfile, which ddrescue currently opens read-only.

Does anybody think that this change is worth the trouble?


Best regards,
Antonio.
