I'm facing a big problem with my LG BH16NS40 BluRay drive after updating Windows 10.
The device won't get recognized by Windows but is normally recognized on the BIOS. On Device Manager, it's listed on hidden devices with error code 45 (device not connected). It shouldn't be a bad cable since the BIOS recognizes it.
There's also an "Unknown device" entry on the Disk drives sublist. And when I go to Disk Management, it asks me to "initialize disk" - it should be the BluRay drive. But I have no idea why Windows thinks my BluRay drive is a hard disk.
I've tried three things I found on the Internet:
None of those solutions solved my problem. I did other things as well:
Note that the drive was working normally on Windows 10 before this specific update (must be one of those three: KB3116278 / KB3140741 / KB3147458).
My system:
Windows 10
Motherboard: Asrock Extreme6/ac X99
CPU: Intel Xeon E5-1650v3 3.5 GHz
RAM: Kingston Hyper X Predator 16GB DDR4
Any help to make me understand what is going wrong would be appreciated! I'm having a really hard time solving the mystery.

I've tried three things I found on the Internet:
Control Panel > Troubleshooting > Hardware and Devices (it reads that changes have been made to the system, but I restarted and nothing changed)
- Delete Upper Filters and Lower Filters entries on the registry. Reboot.
- Open elevated Command Prompt and enter reg.exe add "HKLM\System\CurrentControlSet\Services\atapi\Controller0" /f /v EnumDevice1 /t REG_DWORD /d 0x00000001. Reboot.
None of those solutions solved my problem. I did other things as well:
- I tried to update the firmware (downloaded by LG's website) but it wouldn't find something to update (as far as I remember, there was a message about ATAPI missing or something like this).
- I had also sent LG a support ticket, but they only told me to uninstall IDE ATA/ATAPI controllers from Device Manager. Of course, it didn't work.
- I read somewhere on the Internet that it might work on SATA2 - but my motherboard only has SATA3 connections.
