I have had the same problem for about six weeks and have been to every driver site/ cd/rom Forum on the net. I found my solution right her on pprune computer forum (guy couldnt burn his photos). Anyway I went here:

Dowloaded the tool and have got my cd rom back. Fluke maybe but its worked for me.
Good luck
