[qanda]This thread is about the Lite-On LH-20A1P. Click here to see full specs[/qanda]After I got this drive it did see Dual Layer blank discs. Now it doesn't. It will see a single (4.7GB) disc but when inserting a DL disc it, doesn't show. I can burn a single disc with no problem.
When I put a DL disc in, the drive acts like it's reading the disc. Light will stay solid on for awhile then blinks and goes silent.
I've tried Nero's InfoTool and VSO Inspector and both say the same thing, no (blank) disc in drive even though there is one in there. I put in a commercial DVD and they did show that.
Blank media tried: Single - Sony+R (no problem with that), DL both Memorex and Verbatim (+R).
Nero 7 Ultra
40GB system partition w/ 70% free space
