Not copying to blank disk

Of course I’m a Newb :o I have been using DVD Clone with no problems until recently. I get the files ready for burn to the disk and when I insert one it doesn’t register a disk. It is a few different disks that I have tried that HAVE worked before and nothing. Now I am trying Sony DVD-R. I would have figured better media but they are the same disks I was using. I tried Shrink and XCopy too with same results. I am using a dell XPS with a Optiarc DVD±RW ND-3570A If that helps. Any clues on how fix this? The Newbie forum directed me here. Thanks in advance. :bow:
