Not news whatsoever. I've known for a long time that you're lucky to get better than about 3 years life out of a CD-R (never mind a CDRW). That's one reason (along with space limitations) why I gave up backing up onto CD-Rs; hard drives have much better long term integrity (assuming you keep them virus-free).
