Default DVD/CD RW not reading discs or burning to blank discs

sponsored links

 
Hi,

My PC is about 5 years old and is on Windows XP with an AMD Athlon processor. I have recently noticed that my LG DVD/CD RW drive does not read or burn cds. When one is inserted into the drive it says "please insert disc" when opening the CD's contents.

I have noticed that some people have had the same problem and I have tried doing the following to resolve this problem:


- Uniinstalled all my burning software which included Nero 7 and other various free software I downloaded to ensure it was not caused by Nero. I also followed Nero's removal instructions from there website and used the tools provided - this did not help.

- The device manager shows the drive as working fine, I have removed it and it installed itself upon a restart. This did not fix the problem and neither did rolling back to an older driver as there no older drivers.

- I have modified the drives registry so the "data type" reads 2 which allows it to read and write CD's. This has changed in the registry but the drive still does not have a recording tab when checking its properties and it still does not recognise blank discs or burn to them.

I was going to buy a new drive but some people have already done so and found the sme problm exists. I also wanted to install the latest drivers for this drive but I cannot find the exact model number - where can I find this info?


I would really apreciate any help with my problem as I my pc has started "playing up" recently and i would like to back up my important files incase of a major problem. But due to my CD/DVD burner not working this cannot be done.

Many thanks in advance.

If you can try the drive in another computer to see if it works there or no.

Have you tried removing the upper/lower filters from the regestry as explaind in other posts etc.

One way to get the data backed up nowadays is to use a USB memory stick to copy it all to.

Last resort is to do a format and reinstall of XP.

Thank you for your reply.

I have not had the chance to try the drive on another computer yet but will definately post my results when I do so.

Can you please remind me how to remove the upper/lower filters on the registry as I can try this too?

Also regarding USB sticks, yes I can backup my important files via these but one of the biggest problems is I have approximately 30GB of music!

I will keep you updated with my results.
Thanks once again!
