I want to ask you if you would know what reasons are there,for mother's CD-Rom drive not to read any cd's. She have laptop and yesterday we didn't had internet so she wanted to watch some movies and i tried putting some dvd's in and nada,but those were not original,so i tried with Deus Ex 1 game and it read it,then i tried with stranglehold and nothing again.. What could it be wrong ?

And for USB,i have kingston 16 GB usb which always worked but now when i try to use it i get message

"You need to format disk N before you can use it. Do you want to format it ?" So i click format disk and i get WINDOWS CAN?T FORMAT DISK... :(

So usb its not working now.
