Abstract: In one embodiment, a product includes a magnetic medium having written thereon data in a data track. The data includes encrypted data written over unencrypted data. An indicator of a physical position on the magnetic medium that corresponds to an end of the encrypted data is stored on the product. A product according to another embodiment includes a magnetic medium having written thereon data in a data track. The data includes encrypted data written over unencrypted data. A portion of the unencrypted data is located before the encrypted data on the medium. An indicator of a physical position on the magnetic medium that corresponds to a beginning of the encrypted data is stored on the product.

Abstract: A storage system includes a plurality of drives that write and read data to and from removable storage media communicatively connected to a storage controller. The storage controller receives comprehensible data and divides the comprehensible data into the plurality of data segments comprising the plurality of data units, manipulates one or more of the plurality of data units within each data segment to form the plurality of unintelligible data segments, generates a decoding key based upon the division and the manipulation, and sends each respective unintelligible data segment to the plurality of drives to store upon the removable storage media. The comprehensible data includes a sufficient number of data units arranged in an order of inherent meaning and the unintelligible data segments include an insufficient number of data units to be comprehensible arranged in an order such that the unintelligible data segments are incomprehensible.

Abstract: A system and a computer program product are disclosed for eliminating access to data on removable storage media of a removable storage media cartridge. The system comprises a computer configured to send to a data storage drive a command to eliminate access to data on a removable storage media cartridge, and send to the data storage drive a command to shred at least one key in response to the command, where shredding the at least one key eliminates access to the data on the removable storage media cartridge. A determination to eliminate access to the data on the removable storage media cartridge is based on a number of read and/or write errors encountered for the removable storage media cartridge.
