Hello, I've recently upgraded some of my co-workers' Dell Precision T7400 computers to Windows 7 and the middle blu-ray drive (labelled "HL-DT-ST BD-RE BH20N") doesn't work. I believe it is an Optiarc. Windows is picking it up in the device manager, but it says "This device cannot start. (Code 0)", and it's not listed as a current drive. The firmware I downloaded from Dell's website can't find the drive either, so it can't update the firmware. Does anyone have any idea how to solve this issue? I'm running the 32-bit version of Windows 7. Thanks for your help.
