Important: If you plan to use MLM to monitor media health, Spectra Logic
strongly recommends that you configure LTO-4 drives and later generation
drives in separate partitions and that you do not routinely share LTO-4 media
between LTO-4 drives and later generation drives. This ensures the accuracy of
the LTO-4 media health data.
