I have had a problem with my cd accepting different types of cd's. I purchased some 4x 4.7gb cd-rw disk that I was assured would work on my newer model HP laptop. I had trouble getting a new cd's to format at first, but somehow got one to format and select data. Now my cd works fine with the 4.7gb cd-rw disk, but it no longer accepts the 12x 700mb cd-rw disk. Just sit there clicking over and over, sometimes popping open the cd drive and asking you to insert a new disk. I have lost the ability to format 12x 700mb cd-rw cd's.
