Please forgive me if this is old news about making CD data disks. Having messed around with the XP burning program I switched to the CD Creator that I used to use for Windows 98. Best thing I could have done. I would definately recommend it for making a data CD that is quick and to use. It cuts out all the saving to the hard disk then recopying then erasing.
I found it so much better that I wanted to pass this on to others
