Burner Won't Burn!

Just tried to butrn some data onto a Cd and a DVD, but discovered that my burner had somehow decided to not recognize its own burning capabilities. It read discs just fine, but for some reason it refuses to burn. Two weeks ago it was fine. I have no idea what changed. Please help. I'm using a Matshita UJ-841S on a Toshiba Satellite. If this is a malware problem, i can post an HJ report. Please get back to me ASAP!

Some background on what program you are using to try and burn a disc, and what makes you think the burner doesn't recognize its own capabilities would be very helpful here. The only reasonable answer I can give you is that the drive is bad because you haven't given me anything more to work with.
