Have an ASUS internal DVD drive installed to a windows vista desktop computer. It has the drive letter "D". In the properties, I find that clicking on the drive generates the message: D:\ application not found. I am logged in as Administrator and have set "Full Control" for myself. Properties show Samsung DVD ROM SD-616E ATA Device. How can one troubleshoot this issue. The machine came to me this way and has never worked. It is shared and connections are set at 2. guidance sougnt
