Hi everyone! I also bought a computer with the HL-DT-ST CD-RW GCE-8400B like Kris. And, it used to burn 700MB/80minute CDs, but not NEmore. I've tried to unistall the driver for it and then reinstall, but it still says that the drive needs a new blank disc inserted. Well, if NEone could help us out, that'd be great. Thanks!
