Are you sure the drive supports write access to DVD RAM media? Some optical drives only allow read access (and some do not support DVD RAM media at all). > Is that a bug or WAD? Are you using vold? It seems vold doesn't know about DVD RAM media and always mounts them read/only. That smells like a vold bug. Workaround: Stop vold (svcadm disable -t volfs), and manually mount the DVD RAM media. That should allow a read/write mount. OTOH, when you have an optical drive that supports write access to DVD RAM media, vold is running, and you insert a blank CD-R or DVD-R (!) (not DVD-RAM!) media, "Gnome Media Format" pops up and offers a "low level format" of the media. Apparently some part of the software stack is confused by the DVD-RAM support of the drive (!) and assumes that each and every media inserted into such a drive must be formatable with filesystems. I think this should be changed to check the currently inserted media (!), and only offer creating filesystems if a DVD-RAM media is currently inserted into the drive.
