I have a NEC 3500ag burner, and just bought some Ridata DVD+R DL 8.5gb 2.4x media. I had firmware 2.17 from the NEC site, and when trying to burn using Nero 18.104.22.168, I was getting an error before the burn process even started. The error was something like failed Disc-at-once.
So, I flashed the drive to the newer 2.18 firmware from NEC. The burn process started as it should have. I THOUGHT everything was ok, up until the process nearly finished at 100% then I got an error :
Session fixation error
Could not perform end of Disc-at-once
Burn process failed at 2.4x (3,324 KB/s)
I have successfully burned using Verbatim DVD+R DL discs with no problem. But I found the Ridata for a little cheaper and have read pretty good things about Ridata. I was hoping someone might be able to shed some light on my situation, and give me some idea how to fix this?!
