I have a drive in my machine that Windows 7 lists as a BD-ROM drive. In fact, it lists it twice, along with another DVD-RW drive, when in fact I only have one physical optical drive on my machine.
Given that there's no Blu-Ray logo on the drive itself, I'm presuming that it doesn't actually support Blu-Ray. How can I be sure? And how do I convince Windows 7 it's not a Blu-Ray drive?
