I am trying to determine if my problem is media, hardware, software, or what. And how to fix it.
I bought a 708UF about 16 months ago. I'm running XP, SP1. Dual processors (about 2 GHz, IIRC), 1.5 GB of RAM. 708UF is hooked up to USB2.
I was able to burn DVDs (using Nero) until about a month ago, when I started running into various frequent problems: Invalid field in command, Could not perform end of Disc-at-once, etc.
I've tried various brands of media, and finally got some advice here to try Taiyo Yuden. I just bought a boatload of them, and although Nero burns them with no error messages, there are problems when I test the DVDs.
When I run Nero's File Test/Surface Scan, the Surface Scan shows three little red squares (damaged areas) at the very end of the burn.
And when I run the Nero Transfer Rate Test, I get the mysterious "no additional sense information" message. Two screen shots -- attempts to burn the same files -- are attached. (Hmmm. I'm having trouble uploading the attachments, so they might not be there.) The files are AVIs, if that matters.
One thing I noticed with the Taiyos is that the burn seems to take a lot longer than it did with other brands of media. I don't know if this is normal, or a sign of trouble. All of media is 4x.
I used EndItAll to shut down all applications before burning a DVD. I suspect Norton Antivirus might still be running in the background, although I don't see it listed in my list of processes. I do have Auto-Protect disabled. If NAV could be causing the problem, I'm pretty sure I can figure out how to disable it completely -- should I try that? I think the worm protection and update notification are still running.
Or is the problem more like to be media (if Taiyos don't work, I don't know what else to try!), the 708UF, or a system/connection problem?
I would really appreciate suggestions on how to troubleshoot/fix the problem. I am not a technical person and have no idea what to try next.
I have Nero version 6.6 (just updated it a week ago), so it should be the latest version.
I have never updated the 708UF firmware -- should I do that? Is it easy for a novice?
FWIW, I am able to burn CDs, usually with no problems. It's just the DVDs I can't get to burn.
