If I want to write a "bad" CRC to disk, I have switch the controller to CRC mode. The controller can't convert a "bad" IP checksum to a "bad" CRC. The PI test tooling relies heavily on being able to write "bad" things to disk and read them back to validate that we detect the error. -- Martin K. Petersen Oracle Linux Engineering
