I am using Windows Vista Ultimate Edition in my Sony VAIO VGN-CR220E model laptop.

Today, after switching on my laptop, I found that there is not display of DVD drive when I open 'My Computer'.

I checked 'Device Manager'. There under the 'DVD/CD-ROM Devices', it is showing a yellow triangle with an exclamation mark in it on the icon of 'PIONEER DVD-RW DVR-K17 ATA Device'.

I checked the properties. There it is showing the following message:

'Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)
Click 'Check for solutions' to send data about this device to Microsoft and to see if there is a solution available.'

I don't know what to do further. Even to format my OS, DVD drive is required.

Please help me.

I have tried system restore to the oldest restore point available. Still the same problem persists.

I also tried the for updating of the DVD driver. Windows has searched for the updated driver on internet and after 10 min, it has shown the the driver is up to date.

Have a look here. I had this problem with another Pioneer drive recently and this fixed it.

It might be that you've installed conflicting drivers or more than one different kind of CD burning software (as was my case). Let us know how you go, and as with any delve into your registry, BE CAREFUL.

EDIT: Try LH's suggestion first, mine's a bit heavy handed right enough...:)

Get the DVD s/w and install it again would be my try at fixing this. If it doesn't work, UN-INSTALL the driver and then try to install it again.
