I am using HP Pavilion dv6 laptop. I was working fine but one day when I restart I could not able to see my E: drive which is being used for CD/DVD. I can see only C; drive and H:drive that is for recovery.
And If I go to My computer > Manage > Device Manager I can see CD ROM > DVD Drive but with exclamation mark on it. And If I double click and check for drive update I am getting the message, the drive instralled on your computer is up to date.

Can any one help me to fix this problem.
