Abstract
A method for protecting data on a first storage device from unauthorized access is provided. The method includes copying a data map, such as a file allocation table, from the first storage device, on which the data to be protected resides, to a second storage device. A security key is established for the data map. The data map is then deleted from the first storage device, to render unusable the data thereon. The data map is restored to the first storage device upon successful input of the security key.
