Well...yes....of course a crc of -1 or 1 or is as common as any other value but in the past some people used to use this value as a placeholder for a checksum which was not known....

So...there is this check for "suspicous checksum values" ...and you're asked how to handle it....now in this case you should simply answer "no"...then it's taken as it is and is not transformed into a nodump.
