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.
