Solved! how can i add a cd/dvd drive to toshiba satellite c55

Solution
Assuming there's physically space inside, you should just be able to remove the plate (likely after removing the underside cover) and slide an optical drive in.

Solution
You have to be a bit careful when ordering ... the C series doesn't use the same one as the A and B series.

Portable dvd burners work great and are probably cheaper.
