If you write the CD on SAO mode (using -dao) the whole CD is readble or
your drive or kernel is bad.


If you write in TAO mode, then in theory you are not allowed to read more than
the size value from isoinfo -d.

As mkisofs at least adds 150 NULLed sectors to this value, a I/O error from 
reading filesystem content verifies a kernel bug.
