Behaviour if no file system can be found

Example:

https://archive.org/details/Apple_Chronicle_CDWM1023150Apple_Computer1992

Isolyzer result:

<?xml version="1.0" ?>
<isolyzer>
    <image>
        <fileInfo>
            <fileName>Apple Chronicle (CDWM1023150)(Apple Computer)(1992).iso</fileName>

            <smallerThanExpected>False</smallerThanExpected>
        </tests>
        <properties/>
    </image>
</isolyzer>

Inspection with Hex editor shows that image is corrupted. Maybe isolyzer should give at least some indication that something is wrong (i.e. that no file system was found whatsoever).
