Now, you know you weren't supposed to ask that question...  :-)

My research indicates that vendors don't consider that customers should need
to access the Medium Auxiliary Memory (MAM) - the industry generic name for
an in-cartridge non-volatile memory chip which tracks usage and other info.
The manual "IBM TotalStorage LTO Ultrium Tape Drive - SCSI Reference"
(GA32-4050) fully describes their MAM and how to read and write it via SCSI
commands.  The device driver programming manual (in this case, "IBM Ultrium
Device Drivers - Programming Reference (GC35-0483)) provides many ioctl
functions which make it easier for a programmer to invoke what resolve to SCSI
commands; but in this case I see no ready operation for getting MAM data.
Those ioctl operations are what the handy-dandy ntutil and tapeutil commands
invoke to acquire info, and I see nothing in their doc saying that they can
return it (though it might be implicitly returned from other operations).

All this is to say that with some SCSI programming, the information could be
obtained and presented.  We don't have LTO here, so I'm not in a position to
try this out.  So this remains an exercise for some industrious systems
programmer out there having LTO on-site.
