dvd writer not listed in windows hardware or my co

  whitts 16:27 23 Oct 2008

My LG dvd writer and sony cd writer are no longer listed under hardware, or in my computer.
They both have power and can open the trays, but do not play. I have just installed PCtools Internet Security 2009 from PC Advisor disk (got a full free registed virson). Cheaked all cables shutdown and unluged power from drives and rebooted nothing. Tried a restore point still not working. Use win XP SP2.

Have you checked that the jumper is set for Master for one of the optical drives and Slave for the other?

It's likely though that the cables are still the problem as it would be very unusual for both drives to pack up.

Missing cd/dvd drives can be normally associated with the removal of burning software such as Nero/Roxio/Sonic/Easy CD Creator etc.
And not showing the drive in My Computer.

Try the below link ,if still no luck follow the Procedure of removing the upper and lower filters.

If no joy with the above fix,try the Microsoft Guided Help

If still no joy,follow the manual fix below.

Restore Missing CD/Dvd Drives

Missing cd/dvd drive
If it is showing an error code:
Code 19, Code 31, Code 32, Code 39, or Code 41
, delete the drive.

Then follow these directions for clearing the Upper/Lower Filters: (might want to print this out)

1. Click on Start --> Run --> and type in 'regedit' followed by the enter key ( if Vista Start search or windows+R )
2. Expand the "HKEY_LOCAL_MACHINE" key (looks like a folder) by double clicking it (or
3. clicking the "+" next to it.)
4. Expand the "SYSTEM" Key
5. Expand the "CurrentControlSet" Key
6. Expand the "Control" Key
7. Expand the "Class" Key
8. Please look for a key containing the following string of letter and numbers:
9. High light this key by left clicking once on it
10. On the right hand side you are looking for "UpperFilters" and "LowerFilters" under the "Name" column, once you find these please delete them by right clicking on them and choosing "delete"
11. Please exit the registry by clicking on the "X" in the top right hand corner of the screen

Reboot your computer

.If in any doubt editing the registry,please create a System Restore point first and also backup your registry....The guidedhelp from Microsoft on backing up the registry is a good lesson for anyone to learn. click here

Creating a System Restore point:

Start/All Programs/Accessories/System Tools/System Restore…follow the prompts.

I,m not certain if this works in Vista but in XP if you uninstall the IDE controller running the drives and reboot your drives may reappaer.
