CD/DVD drive will not accept any previously accepted disks.Pioneer DVD-RWDVR-K17RS ATA Device is either missing or corrupted code 39 error. Please can anyone advise on what to do. Instructions need to be very basic because I am not good with technical stuff. Would error on driver affect printer as this has suddenly decided not to print.

Better stil;

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.

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:

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 have a similar problem, it's just that my cd drive is nowhere to be found, not even in BIOS, but when I put a cd in it, it starts up trying to read it. Of course, nothing comes up on the screen but I can hear it turning and all.
I have tried everything i could find inside the forums including to delete upper and lower filters, but those did not excist. I have tried the "Microsoft FIX IT" application, registry repair and so on.
Hope someone can help me with this.
