Hi friends I just need to know what the difference between LG WH10LS30 and LG BH10LS30 writer. You know that I have used both the writers in my computer but were unable to know the differences as both were working normally. Yes but my WH10LS30 writer was giving some problems then finally I replaced it with BH10LS30. I also saw that both of them were running at the same speed. It seems these 2 drives have the same specs so whatís the difference between them? Thus anyone noticed the difference between them?
