retriving information about cd rom drives installed

hi

i was wondering if anyone knows how to find out what kind of drives are installed on a computer. I am creating a program that reads from a cd drive but i realised that there may be more than one cd drive installed.Which would mean the user would need to be able to choose which drive they would like to read from. Is it possible to find out how many cd drives there is on a computer and retrieve their information so that i can add each one to a combo box?

thanks

sorry if its a bit confusing
