Bought an Artec dual layer burner at the beginning of the year. Been working fine for reading DVD's, both data and video, and been OK for burning DVD's and CD's..although had some errors with DVD's this appears to have been down to a bad batch of media. However, last night I got an error when burning a DVD with Nero (Reloaded...version before 6.6.06 which was released 17/01/05). Now my DVD drive won't recognise anything at all. I can put discs in and it appears to be starting to read, but says "no disc" all the time, includng under DVD-Shrink etc. If I press the eject button on the unit it, eventually, ejects the disc but then immediately takes it back again. I've looked through the threads on here and can see people have had similar problems...but can't find a resolution as yet. I've tried updating the ASPI driver to the latest adaptec one, checked cables and master/slave settings etc. Any help and advice gratefully received.
