The restore idea works fine and another solution is to reinstall the CD driver, if you have the disc or go to the manufacture's site and download the latest version.
It's also a good idea to remove and reference on your PC BEFORE you do this as well as making sure your anti virus program is DISABLED!
Many thanks for the advice, I have now got my cd icon back using the link.
The only problem is that I cannot use the drive as it does not have any free space on the cd even though the disc is empty.
Any further help would be appreciated
