Efficient elimination of access to data on a writable storage media

摘要

A system provided for eliminating access to data within a writable storage media cartridge. The system comprises a writable storage media drive, such as a tape drive. The writable storage drive determines if at least a first portion of data on the writable storage media is encrypted. If it is determined that the first portion of data is encrypted then the writable storage drive shreds a second portion of data within the writable storage media cartridge related to said encrypted first portion of data. The first portion of data and the second portion are not the same portions of the writable storage media cartridge.
