help: dvd drive not detected
 

I assume this happened after updates were installed two days ago for Vista 64bit

When I go to My Computer, my DVD-drive is undetected.
I go to Device Manager, and it shows a yellow exclamation beside it. I scanned for hardware changes and properties and I get this

I went into BIOS, and it detected the drive though.
This is a Lite-On LH-20A1S SATA drive.
I mean, I can eject the drive and insert a disc, but it won't read anything.


I also Uninstalled the drivers from Device Manager hoping Windows will install the drivers for me, but then it Failed.

go update the firmware

I updated it last month.

I tried to do it again, but then the Firmware updater won't allow me as no drive can be detected to update anything.

Did system restore before windows update.
Showed my dvd drive.
So I reinstalled those updates and now everything is good.
