Keep in mind that these 2 media are in these _states_ because I try to blank them with software: - one with "dvd+rw-format -blank=full /dev/cd0"; - the other using "./cdrecord-wrapper.sh -v -blank=all dev=3,0,0". >> 2/ A new DVD-RW I *never* used says: >> Mounted Media: 14h, DVD-RW Sequential >> Media ID: TDK502sakuM3 > Are these disks come from same pack?

Yes, I buy 2 packs TDK: one contained 5 DVD-R, the other 5 DVD-RW. So, I can confirm... :( > As for Media ID not being reported for finalized DVD-R.
