View Edit Delete	US8762658B2	In a further embodiment, the apparatus includes an erase confirmation module 1016 that receives a confirmation that the existing data on the storage device 150 has been overwritten with characters so that the existing data is non-recoverable. The confirmation may be forwarded to a requesting device or client 114 and may be used to verify that the existing data has been put in a condition where it is non-recoverable. In other embodiments, the secure erase command may direct the storage device 150 to overwrite the existing data with a specific character or character string or the execute command may be executed multiple times. One of skill in the art will recognize other ways to configure one or more secure erase commands to ensure the existing data is non-recoverable.	251	Added by DJM 3 2021	3/24/21, 12:00 AM
View Edit Delete	US8762658B2	The secure erase command directs the storage device 150 to overwrite existing data so that the existing data is non-recoverable. The storage device 150 then creates the data segment token as well as overwrites, recovers, erases, etc. the existing data. As a result, the existing data is non-recoverable and the data segment token is stored on the storage device 150, which typically takes much less storage space than the existing data.	250	Added by DJM 3 2021	3/24/21, 12:00 AM
View Edit Delete	US8762658B2	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 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.	249	Added by DJM 3 2021	3/24/21, 12:00 AM
View Edit Delete	US8762658B2	The token directive may, however, include other pertinent information for forming the data segment token, such as at least one instance of the repeated, identical character or character string. The token directive may also include metadata, such as a data segment location, an address from a file system, location on a data storage device corresponding to the data segment, etc. One of skill in the art will recognize other information that may be included with a token directive. In one embodiment, the token directive generation module 1002 generates a data segment token along with the token directive.	248	Added by DJM 3 2021	3/24/21, 12:00 AM
View Edit Delete	US8762658B2	The token directive includes at least a data segment identifier and a data segment length. The data segment identifier is typically an object ID, file name, or other identifier known to a file system, application, server 112, etc. seeking to store the repeated, identical characters or character string on the storage device. The data segment length is typically the storage space required by the series of repeated, identical characters or character strings. The data segment token and the token directive typically do not include data of the data segment, such as the series of repeated, identical characters.	247	Added by DJM 3 2021	3/24/21, 12:00 AM
