This is the API to retrieve cartridge information- which I have used frequently.

If you examine the return list there is nothing from that chip in the list. I think it's a GREAT idea for a DCR. :-)

How can I access the number of uses? (LT03 & LT04)

(I was under the impression that I could find usage info in SST, but
that it was reset when the tape was initialized.)

Commonly ignored is that there is a memory chip in each cartridge that
contains 4K (LTO1,2,3) or 8K (LTO4+) of memory which contains
information about the cartridge (cleaning cartridges included!) This
chip is read by RF which is why you don't see it or any connections to
it. It contains the things like the cartridge type as well as the
number of uses etc. The drive reads this chip as soon as it is
installed also preventing the LTO5 tape from being used as an LTO4.
