-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.
