My cd/dvd rom does not work. The driver is HL-DT-ST DVD RRW GSA-H30L SCSI Cd Rom Device. When I click on the driver, I get the message "Windows cannot load the device driver for this hardware. The driver maybe corrupted or missing (Code 39)."
Any suggestion as to what I can do. My computer is a Pavilion desktop a1730n with Vista 32 on it..
Also when I click on driver details it lists:
c:/windows/system 32/drivers/cdrom.sys and
c:/windows/system 32/drivers/GEARAspi WDM.sys
which the computer would not let me open these files.
Please can someone help me, I am at a loss.

THANK YOU VERY MUCH 1badGuard I've been looking for a solution during 1 month, and vualà....I found yours which in some very easy steps helps me and solves the problem quickly and easily! Nobody have answered this post, but I've done it because the other people who have the same problem will know that this is the solution.
My problem was the driver was corrupted and appeared a yellow exclamation icon in device administration. Just delete UpperFilter and LowerFilter from register, unistall driver, click on plug-and-play button and automatically Windows reinstall correctly the cdrom device.
Again thank you very much 1badGuard !!

I am more than impressed with your detailed "alter the Registry" FIX, for this code 39 error.
I normally am afraid to touch the Registry. (I did back it up), but have had problems in the past even restoring from recent backups.
YOU FIXED MY AD-7561S DVD RW drive WITH A CODE 39 ERROR.
I only had the 'Upper filter' on my hp dv6-2157, but after deleting it, it was OK.
I thought it was dead for sure. I Deleted the driver/device and 'looked' for new device to re-install several times, to no avail.
A real THANKING to you from me.
