[[The popular CDGONE patch. CD drives may vanish in Windows Explorer, Device
Manager, etc. if a third-party CD-burning package has been uninstalled and
Registry references for some code modules aren’t removed successfully. This
patch and a reboot usually will restore the missing drives. Any third
party package still required will then have to be re-installed. ]] http://aumha.org/reg3.htm
