Then a single-bit error (even if the controller moves a block around within the disk without telling you) can be corrected by the filesystem driver, and the correct data re-written.
In my experience, flash corruption of the type found in SD cards are completely blank (00) or erased (FF) blocks, not single-bit errors. Remember that SD already has a layer of error correction to handle those from the raw flash.
