Hi - I recently lost the cd/dvd drive in my old Toshiba Satellite laptop. It just disappeared from my list of drives. I Googled the problem and this site was the first to pop up with some helpful advice. I followed the instructions which took me deeper into the System folder than I had ever dared venture, and it worked. I immediately registered and I'm looking forward to solving a couple of issues I'm having with getting the old Toshiba onto my wifi network. It isn't playing nice with my new router. Anyway, I'm glad to be here and hope at some point I'll be able to help some of you out with your problems.
