Hello, I have 3 drives in my pc system displying DVD all displaying dvd but none of them can dvd nor cd. They used to but now they do not. I have so many disks recirded by the very same drives but now they work but only what was prerecorded. Why has this happened.
I would say you need a new CD/DVD writer as it's writing function seems to be faulty. This could mean a laser component has failed.
