I think buffered write is not a problem if followed by a call to fsync, as ddrescue does.

I'm not sure. The block layer might e.g. legitimately buffer blocks in larger chunks.

Not for the input file in fill mode, and not for the output file with the new --synchronous option of ddrescue 1.8-pre2.



I didn't mean the block buffering from ddrescue, but the block layer of the OS kernel.
