My CD-R only accepts a disc once, and if I get new data on the disc it just shows me the old data but not the new data. Even If I delete the old data and put new files on it from a different computer, it only shows me the old files. I tried this with several discs and several brands, so it is a problem with the driver. I think this has to do with some settings but I don't know where they are. Help!!!

You didn't tell us what software you are using. And it is CD-R or CD-RW?
