I also had an LG burner (52x24x52) for 6 months more or less started to sound weird, and suddenly, unexpectedly, the computer recognized it but did not read the shits. Review by all sides, everything looked good, but shit. I think that was the engine that delivered by the sound when putting the CD's (never got Cd's poor, illiterate or record (they were almost all LG)). A week later I buy another burner, but this time SAMSUNG.

I hope this lasts longer.
