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.
Claims20
A system for eliminating access to data on removable storage media of a removable storage media cartridge comprising:
- 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 said data storage drive a command to shred at least one key in response to said command, wherein shredding said at least one key eliminates access to said data on said removable storage media cartridge,
- wherein a determination to eliminate access to said data on said removable storage media cartridge is based on a number of read and/or write errors encountered for said removable storage media cartridge.
A computer program product comprising a non-transitory computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processing circuit to cause the processing circuit to perform a method comprising:
- causing storing of at least one key on a removable storage media cartridge, wherein said removable storage media cartridge comprises a removable storage media comprising data that is accessible with said at least one key;
- receiving, by the processing circuit, a command to eliminate access to said data on said removable storage media;
- and
- causing shredding said at least one key in response to said command, wherein shredding said at least one key eliminates access to said data on said removable storage media;
- wherein a determination to eliminate access to said data on said removable storage media cartridge is based on a number of read and/or write errors encountered for said removable storage media cartridge.
A computer program product comprising a non-transitory computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processing circuit to cause the processing circuit to perform a method comprising:
- generating, by the processing circuit, at least one key for a tape cartridge, wherein said tape cartridge comprises tape media comprising data that is accessible with said at least one key;
- causing storing said at least one key on said tape cartridge;
- sending, by the processing circuit, a command to shred said data on said tape media;
- and
- causing shredding of said at least one key on said tape cartridge in response to said command, such that said data on said tape media is inaccessible,
- wherein a determination to eliminate access to said data on said tape media is based on a number of read and/or write errors encountered for said tape cartridge.
