If you don't have upper or lower filters in your reg, then the problem is not in the register. I had a fujitsu siemens laptop that came with vista. I installed the xp instead and had everything else working but the Matshita uj 850-s dvd-ram drive. The reason that dvd-ram wasn't working with xp was that I had to change the "SATA Controller mode option" to "Compatible" to make installation possible. Because hard drive and dvd-ram were in same area 0, this meant problems with dvd-ram. To get the dvd-ram working I had to do these steps:
3. In BIOS find "Serial Controller mode option" (in fujitsu siemens: advanced\internal device configurations\serial ata controller:\sata controller mode option) and change it to "Enhanced".
4. Make sure that AHCI configuration is marked as Disabled
5. Save and Exit
6. In windows put a dvd in the dvd-ram and test if it works. In my case it did work.
Changing the mode to Enhanced might make your OS to find new devices, in my case "PCI serial port" and "PCI Simple Communications Controller". To get these work you need to install AMT drivers that you can find from your manufacturers website, or Intels AMT by searching google.
Hope this helped those that didn't have Lower and Upper filters in Register. For me it took quite a while to realise where the problem was...
MITSHITA must go by it's middle name ! I have vista 32 bit and my CD?DVD driver keeps giving me error 19. The only way I can find to fix the problem is to BUY THEIR driver doctor. That's not going to happen !! I will make sure my next computer has NO MITSHITA PRODUCT. Isn't there some way to fix this problem without having to BUY something?
I know for sure this will fix your device driver issues. Below is the instructions and link to the official Microsoft "Fix It" program. Microsoft put this on the internet specifically for driver issues with Vista Home Premium. Please let me know if you have any problems with it but it's user friendly and safe to use.
***** NO NEED TO ALTER YOUR REGISTRY *****
Altering your Registry can cause SERIOUS AND PERMANANT DAMAGE to your computer
THIS IS THE DIRECT PATH VIA MICROSOFT FOR THE ACTUAL DRIVERS. THIS WORKS FOR OTHER DVD DEVICES ALSO.
I found the resolution to the Matshita DVD-Ram UJ-850s ATA Device Drivers and it works for many other device driver issues. This works for Microsoft Vista Home Premium Please follow directions carefully or either the Read or the Write of you device will not work. In order for this to work - (YOU WILL NEED A BLANK DVD AND A FULL DVD WITH SOME KIND OF PROGRAM ON IT)
Click (or copy and paste) the link above to begin the process. Click on the first option Your CD/DVD drive cannot read or write media in Windows Vista. Click on the big "RUN NOW" button to the right, then select "Continue" when your computer asks your permission. Then Select Detect problems and apply the fixes for me (Recommended). It gives you two options "Read a CD/DVD and Write a CD/DVD" you will need to run both options separately once for each issue you're having with your hardware. You will see your device listed, click on your device. It will ask you for a disc. For the Read part of it, you need to insert a DVD Disc with something on it such as a program, of any kind. Insert the disc and click on your device.
NOTE: If you forget to insert a full DVD Disc your DVD Device door will pop out, then you will be forced to insert a DVD disc with a program on it. The program will continue and configure your DVD device. After it completes return back to the first page where it says "RUN NOW". Click on "RUN NOW' again and follow the same steps. When you see the screen with the two options "Read a CD/DVD and Write a CD/DVD" and "Write a CD/DVD", this time select "Write a CD/DVD" option.
NOTE: IT IS VERY IMPORTANT THAT YOU INSERT A BLANK DVD IN ORDER TO COMPLETE THIS PROCESS.
The program is configuring the write portion and it needs to be able to write on the blank DVD in order to complete the process. Then follow the rest of the steps and complete the process. THAT'S IT !!! Congratulations, you can now use 100% of you DVD device.
Please feel free to contact me with any questions or comments.
AND YOU CAN BACK UP THESE DRIVERS IN CASE YOU NEED THEM AGAIN LATER
