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

After the above :

References to Vista also apply to Windows 7.

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 continuebelow.

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.

Use DevManView to locate CD/DVD in registry (be careful and make a Restore Point before

changing anything) - find the device in DevManView and then Right Click on it Open in RegEdit.

DevManView - Free - an alternative to the standard Device Manager of Windows, which displays

all devices and their properties in flat table, instead of tree viewer

Hope this helps.
