I've managed to get this working on current by minor tweaks to the umass driver to not ignore certain commands, but to pass them through. This was also independently done by phk, but there's some issues with the simple hack that might destabilize the thumb drives. This ordinarily wouldn't bother me, but the goofy things are fragile enough as it is, and any extra protection there is likely a good thing... You may have a different problem, however. I used cdrecord with the dvd+rw extensions (growisofs) and found that I got many warnings in the log, I was able to burn a dvd in all but one of the cases I tried. That one case I think was a problem with the production of data using dump was so slow that I couldn't stream the data to the dvd. Some blanks tolerated this well, while others didn't (or I got lucky on some, unlucky on others). Without seeing the messages from the applications that you are using, and a complete dmesg, it is hard to say for sure. Warner
