The guy at Roxio told me I had a firmware problem (blamed it on the machine) . The guy at Lacie blamed it on the software !
Later I finally got somebody who acted like they knew what they were doing . Tech at Lacie . Yes the latest (according to Roxio dude) is 2.16 . The Lacie guy said NEC sends with appropriate firmware and they've not done firmware updates , except a few years ago when they used Yamaha drives . He said you'd have to go to a PC and do it . Are you on a PC ? And he acted like that wouldn't be necessary .
If you are on mac you should prob be using Toast and you need Panther , 10.3 , to do double layer burning . Your software might not able to do this . I haven't burned dbl layer yet , but believe me , I went round with this burner . I have now got it sussed out and this burner is Bad A$$ .
So if you're having problems , hang in there . I was getting real pissed, when I called Lacie at first , they said I was the first to call about the 16x . They acted like they didnt know anything about it !
Ask for Matt , Lacie phone tech . When I finally got him to address my problems , he gave me alot of confidence in it cause he acted like he knew something ABOUT IT !!! Nobody else did .
Check your software is my suggestion . And realize they recommend a certain operating system for dbl. layer burning on mac so if you're on PC it might be the same deal .
This burner ROCKS . It's the 3500 AG by the way . The 2510 was the 8x dbl layer .
