"To copy files and folders to a CD
Insert a blank, writable CD into the CD recorder.
Open My Computer.
Click the files or folders you want to copy to the CD. To select more than one file, hold down the CTRL key while you click the files you want. Then, under File and Folder Tasks, click Copy this file, Copy this folder, or Copy the selected items.
If the files are located in My Pictures, under Picture Tasks, click Copy to CD or Copy all items to CD, and then skip to step 5.
In the Copy Items dialog box, click the CD recording drive, and then click Copy."
Thats when the error comes up, as well as coming up when I try to just open/explore the D drive... as I said, music works perfectly...
