First ... uninstall both drives from Device Manager, and then reboot the ssytem.   This MAY resolve this.

Second ... Run RegEdit (Start, Run, Regedit) and delete the Upperfilters and Lowerfilters values from the following registry key:

Then reboot the system.   (this is a harmless registry modification that resolves many issues with optical drives)

First install antispyware software like spybot...Scan ur system for virus n trozens...If nothing happens then re-install the Hardware drivers by going to device manager--> DVD/CD Roms. Uninstall all the drives. Reboot and check!!!

have you upgraded to xp or reinstalled your system recently? if so, do you have the drivers for the drives you mention or can you obtain updated drivers? you may want to install those drivers. if this happened "all of a sudden" without any change in the system environment, then do what sunilswain says.

"This is a harmless registry mod that resolves many issues..."

Whilst this is true if you know what you're doing, no registry mod is harmless if you don't.

If you don't understand how to navigate to the path indicated and make the suggested changes then i'd seriously recommend against even trying this step as you can cause more harm than good.

It IS a harmless modification (the filters are simply recreated when necessary) ... and this resolves MANY optical drive issues.   Navigating to the correct path is VERY simple (if you can navigate around your disk with Windows Explorer you'll have NO problem navigating through the registry with RegEdit) to find the key I noted and then you simply delete the Upperfilters and Lowerfilters [highlight them; right-click; delete].

If, however, you have any reservations about using RegEdit, just do this:

Download this file:  http://www.dougknox.com/xp/utils/XP_CD-DVD-Fix.zip

Extract it; then just double-click on the EXE file ... then reboot.   This utility simply makes the registry change I noted earlier for you :-)
