Problem with Plextor 716

I burned a disk the other night with the plextor 716. Nero said burn successful. The next day when I was going to install what I burned it did not recognize the disk. Shows nothing is on the disk. I can’t burn anything on the disk so the disk thinks it has been burned onto which I guess it has, but my computer cannot read anything that the plextor has written on it. I tried a couple of different media with the same results. I fear the drive is bad but do not know nearly as much as some of you folks on here. Know of anything I might try or I am looking over.
