Abstract
A data cartridge and method for providing a write-securable storage medium that inhibits writing. The medium comprises a write-secure-type indicator in a predefined location that indicates the medium is of a type that is susceptible to write securing. Additionally, the medium comprises a write-secure-complete indicator in a predetermined zone of the disk that is not accessible to a user. When the write-secure-complete indicator is set by a host device, the setting is irreversible and consequently the data on the medium is protected, and additional writing onto any part of the medium is permanently prevented.
