I have never experienced the problem you describe so I cannot give you any help there; however, I would like to give you a few words of caution about using rewritable disks--just based on my own experience, of course.
When the rewritable disks were first introduced, the touted they were rewritable up to 1000 or 10,000 times. I've forgotten the exact number; but, it was in the thousands. Well, I began to experience read errors after as few as five rewrites in some cases and I don't think I ever got much over about thirty rewrites with any disk before disk read problems began to surface. The biggest problem here was that there was never a warning; I would find out when it was too late--when I needed to recover the written data from backup.
You see, there is no way for a CD burner to identify and mark a portion of the disk that goes bad like there is with hard disks and floppies. So the burner just continues to write right through the bad section and you don't find out you can't read that data until you try to read it back.
So, be careful about rewritables. Personally, I eventually discarded about 60 or so rewritables, many of which were still in their celophane wrappers and had never been opened. And, I no longer even install the packet writing software on any of my systems because I just have no use for unpredictable storage media.
