LG gsa h12n will burn, but can't read

Hello all, I recently purchased this new dvd burner, it will burn ok but it wont read more than one good disc.I have tried several cd’s with audio files and jpegs, it shows the files are there when you explore the disc, you click to open the file and it just spins for a while then the read led goes out on the drive. I puzzled, please help, is my drive a bad one ?

Have you tried to reinstalled the drive?
