CD burning drive won't burn CDs

A very long time ago I either formatted a CD, wrote files onto a CD, or just deleted them off of the CD, and if I formatted it I don't remember if something went wrong or not, if I just deleted/wrote files onto/off of it, I think it worked fine. Like I said it was a very long time ago. A few days ago I tried to burn a video onto a DVD, as I'm not sure if this drive can burn DVD's or just CD's. It didn't work, tried another DVD, it didn't work. Formatted it, that didn't work. Today I tried a CD, it didn't work, tried to format it, it didn't work. Tried another CD and it didn't work either. I only tried different versions of the same software for the DVD, and different software for the CD. I used imgburn for the DVD and Free ISO burner for the CD. They both errored. The imgburn error said something about a sector write error, and the Free ISO burner said
"Initialize ...
Starting to write ISO Image ...
Failed to write ISO image, Error: Hardware Error 9728."

I tried imgburn with the CD just now, I used DVD flick to make the file, so I'm not sure if it messed up because it thought it was a DVD or not. the imgburn error said something about I/O operation and power something being full. I couldn't save it and write it here, it was a pop up message.

What is wrong with it?
