I had DAEMON Tools installed and I then upgraded to the latest version 3.44 and now I have 2 virtual drives even though DAEMON says I only have 1 enabled and if I disable all virtual devices in DAEMON, 1 virtual drive still remains.
i would uninstall the proggy, then look in device manager for any scsi drivers related to the virtual drives. uninstall and reboot, hopefully they will be gone. if not running msconfig will show you the startup location of daemon.exe, go in regedit and delete it. once its gone reinstall the new version.
