So I turn on my laptop this morning and put a disc in to install something when I notice that there is no icon in My Computer for my DVD drive. When I put the disc in, the light on the drive flashed on and off for about 15 seconds and then stopped. I found the following error in the Device Manager:
HL-DT-ST DVDRAM GSA-T20L ATA Device:
Windows cannot load the device driver for this hardware.
The driver may be corrupted or missing. (Code 39)
I tried uninstalling the driver and restarting, but I’m still getting the same error. Yes, I am using Vista, which is probably why this is happening in the first place. But the drive always worked fine before, and I am not sure what could have happened to mess up the driver. Only thing I can think of was the Nero update I ran yesterday. I may have to try uninstalling that to see if it’s my problem.
Well I did a little searching and this is what I found from this forum:
(REMEMBER: nobody is at fault if this does not work but you, but if it helps, awsome! :eyebrowlift:)
From Microsoft… this takes about 5 minutes to do…

Hmm, I don’t know if this makes a difference, but that guide is for Vista x64 and I’m on the 32 bit version. Also, that seems like a risky and difficult procedure, not to mention that I’m getting multiple files for the {4D36E965-E325-11CE-BFC1-08002BE10318} file.
I’ll just try uninstalling Nero and see if that helps. Any more ideas?
