160 HP Ultrium Drives and Tape Cartridges Appendix A
LTO-Cartridge Memory (LTO-CM) Issues
The LTO-CM stores information that is normally stored in the header at the
beginning of the tape, including identification and usage information such as
the number of times the cartridge has been loaded, when it was last cleaned,
and error logs. If the LTO-CM becomes damaged, you may experience
difficulty with the cartridge.
