I am having a continuous problem with files being lost on/cd-rw's. I have been told that you can't fill the cd due to overwriting of critical files. I use roxio 5 software and a sony cd-rw. I had just enabled XP shutdown proceedures which work in concert with my APC back-UPS and noticed the hard drive started going...and going...and going for about 10 to 15 minutes. The machine wasn't locked up but I thought I better restart the system. My cd-rw was only about 1/2 full and now I've lost a bunch of stuff and couldn't even read from it until I rebooted and now roxio doesn't see it. It's using I think the XP interface which gives no usability to the device. I'm always having problems with this media in regards to saving files. Do you know of any methods or whatever to enable me to use this as a viable storage device. Any help is greatly appreciated. Mike
