Can't say I've ever had to many problems with making back ups with CloneDVD, but for the past month I've had problems. I continually get and error message that "the source data is too large. The writer is not capable of writing the data requested". or to "place blank media in the drive". Both of my drives are capable of writing to DVD's, as I have done this many times before. The media I'm using is Memorex and Maxell. I did try several from both packs. I have recorded on both before. but all at once, nothing works. Any idea's. And I have followed the suggestions made by the Clone program. The files are no larger then any others I've recorded.
