I apologize if this is in the wrong section -- I am using Windows 7. I just installed a second DVD RW Drive (Sony Optiarc). When I go into my computer is shows my HDD (drives C and D), DVD RW drive E, DVD RW drive F, and CD drive L. I don't have another CD drive installed. Can anyone tell me what this "L" drive is and what I should do? This extra drive does not show up in Win XP. Thanks.
