A Hard Drive is a data storage device used for storing and retrieving digital information using one or more rigid ("hard") rapidly rotating disks (platters) coated with magnetic material. Invented in 1972 by IBM under the name "Smart Drives", hard drives work by a magnetic head on an acutator arm "inscribing" (or writing) data to the platter. Think of someone writing in a book, where the pen is the magnetic head and the platter is the paper. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order rather than sequentially.
The CD was invented in roughly the same time period. When it was invented, it held more data than a Hard drive. Now it is the complete reverse.
For data security, Fucko and Encryption might be of use to you.
For securely wiping data, Data Destruction might be of use to you as well.
