Where is my drive gone/

hi . When i go in to nero and try to copy a dvd my sorce drive is there but i cant find my destination dvd drive! this was all fine last week. What can i do pls??

ed go into the Device manager and locate the drive in question! Right click it and choose uninstal or remove I can’t remember what it exactly says. Then lose the computer and upon restart the computer and operating system will recognize the drive and reinstall it and all should be fine!
