>I was wondering if anyone has a simple way of verifying if a CD or DVD drive has media in it. I have code that figures out what drive letters are the CD and/or DVD drives. Next I want to see what is on the media of these drives. If it is empty I want to skip over it. But I can't figure out how to tell if the drive is empty or not other than using 'SET DEFAULT TO d:\' and getting an "invalid path of file name" error if the drive is empty. Any ideas? Thanks!
