I just noticed this all at once today. The PC in question is my main rig, in my sig. I went to mount an ISO today, as I always do, by running Daemon Tools Lite (newest version), and assiging the ISO to my one virtual drive. Well the Autorun didnt pop up as it usually does, so I went into "Computer", and was surprised to not see anything at all apart from my hard drives. The DT Virtual drive is always there, along with my internal Samsung DVD writer. They are ususally drives D: and E:. Now I went into Device Manager, and my DVD drive is listed there, but with a small exclamation point nest to it. In the Properties for it, it says the drive could not be loaded because it is missing or corrupt. So I uninstalled it, then rebooted. Once rebooted, Windows saw the drive, and tried to install the drive, but failed. Something is affecting my optical drives, physical AND virtual. The only things I can remember installing recently that might conflict is VMWare Workstation 6, and MediaMonkey. Both of which I installed from installers I downloaded, so i dont know if the DVD writer was working before, but i suspect it was, as I installed The Orange Box about a week ago with it. Anyone have any opinions on what could be causing the issue?
