That's certainly interesting! Didn't know that :) And you are right that
the tapes have to be unused
(https://www.ibm.com/support/knowledgecenter/en/STQRQ9/com.ibm.storage.ts4500.doc/ts4500_ipg_3584_lto_m8.html)
I also had another thing wrong, LTO drives (1 to 7) can read two gens
back but write only one, not two...

LTO technology is backwards compatible two generations from 1 to 7 and

I'm not sure why you would like to label an LTO-7 as LTO-8 tape (will
most likely cause trouble) but you can do so by using an LTO-8 barcode
tag (last element in the barcode tag is used to define the LTO
generation, so L8 whould do the trick) I create the ones I use here:

You missed a detail. Labelling an LTO-7 tape as LTO-M8 enables you to
get a 50% capacity increase *on LTO-7 media* in an LTO-8 drive.
(Whereas native LTO-8 media is double the capacity of LTO-7.) But I
believe it has to be never-written new media.
