Click start control panel administration tools computer management device manager scroll down cd-dvd rom drives you might see a yellow question /exclamation mark ? ! or a red X right click to update driver

you might have to physically unplug the leads for this cd/dvd restart your computer then plug them back this should activate the found new hardware wizard

if this does not fix the problem it might be a registry problem if you cant see your disk drive in windows explorer
Close all open programs

Click on Start, Run, and type regedit and press Enter
Click on the plus signs (+) next to the following folders

HKEY_LOCAL_MACHINE

SYSTEM

CurrentControlSet

Control

Class

{4D36E965-E325-11CE-BFC1-08002BE10318}

This folder is the DVD/CD-ROM Drive Class Description in the registry. Look for any of the following names in the right hand column.

Upper Filters

Lower Filters

Upper Filters.bak

Lower Filters.bak
If any of the above keys shown in step 4 are listed, right-click on them and choose Delete

After deleting the keys, close the registry editor
Reboot your computer

Open My Computer and check to see if your CD or DVD drives have returned. You may also want to open Device Manager and verify that the yellow exclamation and error code on the CD or DVD drive is gone.

SOURCE: read only cd-r not dvd

Have the same problem, it used to work and suddenly it wont do it anymore. I guess this is due to windows XP updates. Windows says that the driver is up to date and I also installed the latest firmware. I am using Nero 7 to burn. I had troubles before but somehow fixed it. Now when I insert a DVD (data) and try to open the dvd drive the whole computer hangs. The content shows for a moment before the computer freezes so it IS in the DVD.

SOURCE: Sony CRX300E CD-RW/DVD-ROM Combo - DVD doesn't read

Hi,
do you have software/program that supports DVD.
Try a different DVD/Movie/Disk or alternative.
Also install a program, such as Nero which will give you physical characteristics of the drive.
Finally go to device manager, and remove or uninstall the device, reboot the computer and setup again. This can sometimes remedy the problem.
ensure that the drive is set as Master/Slave. if on the same Bus/IDE channel as a hard-drive. set as master/slave opposite to what the hard-drive is setup as.
Hope this helps.
Mike @ Compurepair.

My lenovo 3000 n100 is not reading a sony dvd-rw.although the cd is inside the computer,it is still showing enter a disk


It sounds like you need to replace your drive. If you've tried multiple cd/dvd's you probably need to replace the drive.

I have a t400 lenovo and I can't seem to hear any sound or be able to adjust the sound or mut. I could at one time, but now nothing


goto control panel > device manager > sound and audio devices and check for the device status.... if its not working properly the you need to reinstall the driver, this will fix the issue.... or please make sure that did you removed any windows components from add/remove programs.... if so, then do that again and enable all windows components, in that case it may ask you to insert the windows cd/dvd in the cd/dvd drive.....
