Well I have seen them interfere in some cases, but maybe it depends on
the version.  Given I hate windows popping up and auto mounting when I
insert disks, I get rid of those things in general.  At least the volume

Perhaps asking the cdwrite mailing list where the growisofs developers
seem to hang out could get some better ideas.  After all they actually
know how this stuff is suppsoed to work.
