Optiarc ad-7170A reads, but will not write

The drive reads, but will not write either to dvd or cd, using either windows or nero7. Windows gives a generic error, nero gives the “cannot connect to trf” message. I’ve increased the size of my page file as recommended by this thread http://club.cdfreaks.com/showthread.php?t=104720 but no joy. I’ve also uninstalled daemon tools, although I think the registry change was blocked by ad aware…

I was poking around in my bios looking for the DMA setting, but couldn’t find anything.

Here’s my nero info tool dump, minus the lengthy “driver information” section.

Any insight would be greatly appreciated.

I also uninstalled and completely reinstalled Nero, as several other users of the TRF thread recommended. I can now burn CDs, but still no luck with DVDs.

Then try to drive in another computer.
