No symlinks were created - not good!

Does lspci show 00:04:06 as a SCSI or IDE controller? (The
controller the drive is on.) For a drastic fix, you could create a
backup of the file, delete everything from # DVD to the end of the
file, and reboot. It should create the proper entries. But I am not
100% sure - that is why you make a backup. :)

You can also try renaming the file, and see if a new one is created.
I believe it will be, but it is hard to follow the logic between the
different batch files and 75-cd-alias~rator.rules
