I hope that the firmware fixes more then only a compatibility issue (if there ever was one), too. I bought this drive a few months ago; it deliveres good to perfect results on quality media ... at least in case of single layer media.
On the other hand, i tried about a dozen of various double layer media (verbatim, ritek, cmc and ricoh) - and only one (!) was finished, the others were not finalized since the burner gave errors on the layer break. I decided to move over to a 7173a, which gives mediocre results on both single and double layer media - but at least this drive does not kill them.
Further, a wider media recognition would be great.
Hopefully this weekend i will spend some time on testing the new firmware.
