My disc drive isn't working and I found this solution on this site http://www.vistaheads.com/forums/microsoft-public-windows-vista-hardware-devices/39472-code-10-19-dvd-drive-resolution.html#post168575 which was from http://www.vistaheads.com/forums/windows-vista-home-premium/88055-matshita-dvd-ram-uj-850s-ata-device.html. I would like to know if I was to apply this edit, it wont screw up my computer, as when the registry screws up, its very unlikely it'll be able to boot hence making my job of recovering my data and computer a lot harder.

Thankyou very much

Short answer: Joe Hepperle was right — the registry tweak people share (removing the corrupted CD/DVD filter values) is a legitimate, Microsoft-documented troubleshooting step for Code 19/31/39-type device errors. It’s intended to remove only the UpperFilters/LowerFilters entries under the CD/DVD class GUID; done correctly it won’t “brick” Vista/Windows, but it isn’t guaranteed to fix every case. See Microsoft’s guidance for this fix. (support.microsoft.com)

Before changing anything, make a recovery snapshot and export the exact key you’ll edit. From an elevated prompt you can export the class key (or use Regedit → File → Export). Example (run as Administrator):

Registry path:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

Quick export command:
reg export "HKLM\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}" dvd-backup.reg

Also create a System Restore point or full registry backup first. If anything goes wrong you can import the .reg file or restore the system. Microsoft documents both the filter-value removal and registry/restore precautions. (support.microsoft.com)

If Elihu5991 tried the edit and it didn’t help, common reasons are: the Upper/Lower values weren’t present (so the problem lies elsewhere), the driver stack still needs a reinstall, the IDE/SATA controller drivers or BIOS settings are blocking the device, or the drive is failing physically. Follow Microsoft’s next steps: uninstall the CD/DVD device in Device Manager, remove/reinstall IDE/ATAPI controllers or try the Controller0/EnumDevice1 registry method, then reboot. Borrowing a known-good drive (as Rushix suggested) is a practical hardware test; swapping cables or testing on another machine helps isolate a dead drive. (support.microsoft.com)

If the system becomes unstable or you lose burning-software features after the change, reinstall affected apps or undo via your exported .reg or System Restore. If all software steps fail, the most reliable path is a hardware test (external/another drive) or having a technician check power/cable/BIOS — sometimes the fix is replacement, not a registry tweak.

Since Rushix is lazily using the internet as if it is a cell phone being used for texting, I have difficulty comprehending her response. The answer to Elihu5991 is, yes, that is a legitimate registry entry.

@ Rushix - I can't get a spare drive from a friend adn I don't have a bootable xp disc. My pc is Vista

@ Joe Hepperle - So this edit wont screw up my pc? Instead, enhance it?

Member Avatar for Joe Hepperle

Elihu5991 - Yes that is correct. The registry edit you proposed will not screw up your computer. Your computer will boot up after making this change. The web link that you gave (at Vistaheads dot com) describes a three part process. First, uninstall the device in Device Manager. Next, apply the registry edit that they give on their page. Finally, restart your computer. The worst thing that could happen is that you might lose functionality in certain CD recording programs. If that happens, simply reinstall those programs. Please note that my answer here is not intended to be the 'fix' for your original problem. My answer here is a response to your inquiry as to whether or not the registry entry shown on the Vistaheads dot com website is 'legit' which I understand to mean 'safe'. It is 'legit' and it is safe. It will not screw up your PC. I don't know if it will 'enhance' it or not.
