I called LG and told them what was going on with the BH 14NS40. they said it was a firmware problem and that was covered under there warranty and they will replace it with a new one. they did not have a firmware up date as of now. I also have a BH 12LS38 for my other drive and I wish I would of bought another one for my 2nd drive. in my other computer I have 2 more lg’s that never had a problem in 2 years. I do not like the BH 14NS40 and would tell anyone to get the BH 12LS38 instead.
