|Hi Abhimaacindia, |
you have not advised pc make, model, laptop, desktop or what.
A CD drive is never going to read a dvd. A DVD drive will read a dvd and cd.
Best thing is to try a cd/dvd cleaning kit. These clean the lense(s)
Here in the UK a kit costs a £1 in the cheapo shops c/w the cleaning liquid.
If cleaning fails, and pc is desktop, try another (borrow?) drive.
Drives are cheap and tend to be throwaway rather than repairable.
Please advise back on progress.
Good Luck - Keep us posted.
