Unfortunately, I have the same problem. I bought a big new set, from COSTCO of blank CD-R's. I'm trying to put photos onto the blank CD's, but each time it says that it can not copy onto. And says that I must REMOVE WRITE-PROTECTION on the CD. ???
Did you ever get this solved? I have the same question as you and can't find an answer online. They are brand new blank CD's CD-R, 700MB.
you may have to format the cd that should help. just right click on it
