Abstract
A data storage library is described including a tape cartridge possessing an auxiliary memory device adapted to maintain a load count that is incremented whenever the tape cartridge is loaded in a tape drive. The library also includes, a library tape drive adapted to increment the load count every time the tape cartridge is loaded in the library tape drive, an auxiliary storage device capable of maintaining knowledge of the incremented load count only from when the tape cartridge is loaded with the library tape drive, and an auxiliary memory device reader capable of reading the load count from the auxiliary memory device. The library further includes a processing device adapted to receive and compare the knowledge maintained in the auxiliary storage device with the load count from the auxiliary memory device that is read via the auxiliary memory device reader that if different, the processing device is capable of transmitting a notification to an end user.
