Paragraph Number

255

In one embodiment, the token directive generation module 1002 generates both a token directive and a secure erase command in response to a request to overwrite existing data on the storage device 150. The existing data includes data identified on the storage device 150 with the same data segment identifier as the data segment identifier in the token directive. Typically, a request to overwrite data is sent where it is not sufficient to merely mark data as invalid or garbage, delete a pointer to the data, or other typical delete operation, but where the data is required to be overwritten in such a way that that the data is not recoverable. For example, the request to overwrite the data may be required where data is considered sensitive information and must be destroyed for security reasons.
