Q: optiarc dvd rw ad-7560s ata device

My DVD/CD ROM won't work. it says on the device manager that "Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)". i wanna try these steps i've read on the forum:


Can you please attempt these steps?  Please be very cautious when editing the registry.  If you would please not delete anything just yet.  If you would please perform the following steps....If Upper and Lower Filters is not within this Registry Key, please simply exit the registry.  

To resolve this problem, remove the affected filter drivers. To do this, follow these steps:
  1. Click Start
    Collapse this imageExpand this image
    , type regedit in the Start Search box, and then click regedit in the Programs list.

    Collapse this imageExpand this image
    If you are prompted for an administrator password or confirmation, type your password, or click Continue.
  2. Locate, and then click the following registry subkey:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
    Caution There can be many instances of the registry subkey that is mentioned in step 2. You must make sure that you are in the appropriate registry subkey before modifying the UpperFilters and the LowerFilters values. To verify that you are in the appropriate registry subkey, make sure that the Default data value is DVD/CD-ROM and the Class data value is CDROM.
  3. In the right pane, right-click UpperFilters, and then click Delete.
  4. Click Yes to confirm the removal of the UpperFilters registry entry.
  5. In the right pane, right-click LowerFilters, and then click Delete.
  6. Click Yes to confirm the removal of the LowerFilters registry entry.
  7. Exit Registry Editor, and then restart the computer.
If you would please follow up with me at your earliest convenience, I would greatly appreciate it.

Thank you,

Hi,

Code 39 means the driver is corrupt or missing.

Stage 1 : Please do all the below even if you have done some before as it is often the total
process which solves the issue.

Try this - Control Panel - Device Manager - CD/DVD - double click the device - Driver's Tab -
click Update Drivers (this will likely do nothing) - then RIGHT CLICK the drive - UNINSTALL -
REBOOT this will refresh the default driver stack. Even if drive is not shown continue
below.

Then work your way through these - remember the drive could be bad, could have a loose
cable or slight corrosion on the contacts (usually for a laptop) and other issues.

Another possibility is that the cables are loose. Remove ALL power, then check cables in both
ends. Remove and replace, do not just snug. For laptops you can often clean the power and
data contacts with a pencil eraser.

Some DVD drives do not use the Windows default drivers so check with the System maker and
device maker to see if there is firmware or drivers for you drive if needed.

===============================

Stage 2 : You could have drive issues as the CD/DVD is actually 4 drives in 1 case ( CD & DVD
burn and CD and DVD read). So it is not unusual for 1 or 2 parts to not function while the others
do so properly.

Did you complete the troubleshooter for the drive that still does not work? There are some
registry entries that the troubleshooter does not fix and those "might" be the cause.

Check with your System Maker and Device maker for both possible firmware updates and
the correct Registry entries for your drive.

These are the keys I think are the ones in question - for the CD/DVD drive sub-keys of course
as there will other sub-keys in these keys. Be sure to ask for specific keys involved as well as
the settings.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\IDE

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Hardware Profiles\0001\System\CurrentControlSet\Enum\IDE

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

You probably can find more info here and maybe even the exact registry settings for your CD/DVD
drive from someone with the same model.
