Using XP

On grandbaby's computer, which is a Dell Dimension C521, when I put a blank CD in the removable drive, the computer does not recognize it. After I have put the CD therein, I click on My Computer, click on DVD drive, I get a message that says Insert disk in drive D. It is as though it does not recognize a blank CD.
I also note that on my own computer, the drive is called DVD/CD-RW drive. On the baby's computer, it is called a DVD drive.
What is the problem? How can I burn files to the CD if there is no CD drive?
