Yes. AFAIK, no mounted FS can be easily (I'm not sure about impossible)
"reformatted" or "erased" (both are effectively removing the file
system). One of the nice things an OS does (or should do) if prevent
destruction of "active" file systems. If mounted, it is active. Try the
umount and then working on it. BTW, for DVD if IIRC, you _might_ need to
"format". Unsure of that though. I know a "virgin" needs formatting.

Maybe the desktop ICON can be right-clicked and cause an unmount without
ejecting and making the icon disappear? If so, then that would let you
continue to operate on it via the desktop tools.

I've not tried that, but it _seems_ it should work. I mean, if the
desktop can recognize a "blank" media and allow you to format, burn,
etc., even though there is no file system there, it should not (IMO)
remove the icon just because it is unmounted. Once unmounted, the media
is not "active" and could (s/b IMO) be treated just like a blank media.
