As to the "in use" part, I'll make a SWAG (Scientific Wild-Ass Guess). With a normal desktop, when you insert a CD/DVD that has something recognizable on it, an "automount" occurs that gives you access to the thing from your desktop. I know notthing about the k3*, so I don't know if the following is possible. Is it possible that it is mounted as another user? If it is mounted at all, does k3* allow you to erase, write, etc? I would think that it would need to be un-mounted for that to occur. That's all I can think of. Can you right-click on the icon and see what the system thinks about it? What does a mount command show? > > Thanks. > > mhr > <snip> Sorry I have nothing more knowledgeable. I always use the cdr tools for my stuff. HTH -- Bill
