Welcome to BaO, em122.
Apparently this is often caused by something called cloneCD (although it may be another program used to "burn" CDs or DVDs).
From what I can find about the problem, you may be able to get around it by removing the tick from "hide cdr media" (I've no idea where you find the tick box though).
Alternatively, if that doesn't work you may need to uninstall cloneCD. This sounds a bit severe (it's just what I found by searching online), so if you do this, keep any registration information so that you can reinstall it again if you need it.
By the way - a friendly tip - please write in proper words rather than abbreviations. It makes things much easier to read, and we have members from all countries here, so it's probably particularly difficult for them if abbreviations are used. Thanks for understanding.
