Best Answer

A CD is a small removable and portable plastic based disk with a thin layer of metal that reflects the laser that reads it.

The hard disk is solid metal and spins inside a reader that uses a magnetic field to read the data. It is sensitive to damage and can easily be destroyed just by dropping it.
