I have a HP laptop with an Optiarc 7560a DVDRW drive. Until recently I had no problem burning DVDs and CDs on it. I use Nero Vision to burn DVDs and either Nero Startsmart or itunes to burn CDs.
I am literally in the middle of a 100 stack of CD-Rs that I have been using and just burned a DVD.
When I try to burn a CD, the drive no longer recognizes the CD-R. It continues to say insert blank disk.
