Those PACKET WRITING drag to disc usually fail after some time. Did you uninstall then reinstall the software that gave you this drag to disk feature?
I've seen this problem before but never really knew what to do about it. When I place a blank CD in the CD-RW drive and try to copy files to that drive, it keeps coming back telling me that I need to insert a disc. Tried several new discs with no success. The system is a Dell desktop running Windows XP SP2. I'd appreciate any suggestions. Thanks.
