I recently installed a Samsung SH1812D to the master drive to replace a DVD-ROM that wasn't working. It complements the LH (sorry, I don't have the model name off hand since I'm at work) DVD-RW burner on the slave drive. I was able to burn CD-R's without any problems prior to the drive replacement. Today, I tried to burn a CD-R. Both drives recognize the blank CD-R initially, but neither one will burn the data disc stating that I needed to use a blank disc. I used tried using two blank discs (that's all that I have left) and both gave the same message. Is there some kind of conflict with the new drive? How can I go about finding out what the problem is? Incidently, I am using Roxio 7 OEM which has never given me a problem before with this particular function.
