Abstract
A disk drive is disclosed that utilizes an additional address mapping layer between logical addresses used by a host system and physical locations in the disk drive. Physical locations configured to store metadata information can be excluded from the additional address mapping layer. As a result, a reduced size translation table can be maintained by the disk drive. Improved performance, reduced costs, and improved security can thereby be attained.
