Content
In one embodiment, the apparatus includes a secure erase module 1320 that overwrites existing data with characters such that the existing data is non-recoverable, where the existing data includes data of a data segment previously stored on the storage device 150 identified with the same data segment identifier as the data segment identified in the storage request. In this embodiment, a data segment token is stored with the data segment identifier and data segment length and existing data identified by the same data segment identifier stored in the data segment token is erased by overwriting the existing data. Typically the existing characters are overwritten by zeros, ones, or some other character string so that the existing data is destroyed and is non-recoverable.
