In a 1000 years even if they don’t have the drives, as long as they still know roughly how it works maybe they will photograph it with a microscope and read the tracks in the M-Disc from that. Then they will have to decode it also of course.

Maybe. The question is why are we needing to read these disks in a thousand years. I would guess right now that the most likely case is information we care about is archived on modern formats such as hard drives, which are constantly being copied to different drives as the old ones go out and so in a thousand years they'll still have all the data in a much more accessible format than a very obsolete disk. If, instead, we are talking about some human disaster and, that constant copies is lost at some point, we're kind of stuck. I don't think the technology to read those disks will exist either, even though in theory, yes, that could be done. It would be a massive reverse engineering effort and I don't think they will even know to start doing that with these weird disks that the agents had. If you want something archived for a thousand years, well, we know that clay tablets baked worked, although we sometimes can't read the letters but at least seeing something with the eyes says there's something and if there's enough of them we have decoded language. The best archival paper in ideal conditions lasts more than a thousand years, but in more typical storage, we can't store paper that long. Paper has only been stored successfully in Egypt for that long. I'm sure there are other deserts though that would count just as well.

  Issue with storage is you need shelf stability without ongoing electrical/mechanical work refreshing data time to time. Masked ROMs and M-Discs are those two things which can really last a very long time; Floppies, Hard Disks, Solid State Storage and present day ROMs all require periodic costs, efforts and refreshes to keep them going (that means they can't be kept in storage and then re-opened in 30 years). We also need a mechanism that outlasts that archival lifespan so how to read Discs or Masked ROMs and how to interpret them, also needs to be stored as well. Repairing electronics is a valuable skill that needs to be passed on across generations as well. Keeping humans around seems to be the best bet, given how things are going, I wouldn't count on the present set of beings around to preserve any of this information that well either.

    > Issue with storage is you need shelf stability without ongoing electrical/mechanical work refreshing data time to time. For what? Nothing we do today will be even remotely important in 1,000 years. Any tiny fraction of a fraction that is important will have been copied thousands, millions, or billions of times into various formats. "I met a traveller from an antique land Who said: Two vast and trunkless legs of stone Stand in the desert. Near them, on the sand, Half sunk, a shattered visage lies, whose frown, And wrinkled lip, and sneer of cold command, Tell that its sculptor well those passions read Which yet survive, stamped on these lifeless things, The hand that mocked them and the heart that fed: And on the pedestal these words appear: "My name is Ozymandias, king of kings: Look on my works, ye Mighty, and despair!" Nothing beside remains. Round the decay Of that colossal wreck, boundless and bare The lone and level sands stretch far away." - Ozymandias - By Percy Bysshe Shelley

        You know what every one of those things says in common? every generation between when it was created and now has decided it was important and made effort to preserve it. We have no clue or maybe only slight clues of what was lost because at some point some generation decided it wasn't worth preserving. Sometimes it was a hard decision for that generation when they realized they couldn't preserve everything, other times it was not cared about at all. Either way though, it was lost for all time because the chain of caring enough to preserve it was lost.

  I think 1,000 years maybe doesn't matter that much. However, these predictions are imperfect. If they're aiming for 1,000 years, that makes me more confident the disc will be readable in 100 years, which may matter more.

Well, paper would best be stored in a fairly dry place, so deserts may be a starting point. Generally the only institutions / organizations that have managed to survive for centuries / millennia have been monasteries.

    Lots of old books survive. They survive because someone cared enough about it to make a copy. Before the printing press, that was entirely by hand. one of the main purposes of those monasteries you mentioned is to copy relevant works for the next generation. Well, maybe I should say the next ten generations or however long books last depending on the local climate. Burrowing stuff sometimes works, however, a lot is lost. Even when we attempt to save things, it often doesn't work. Some years ago a town near me had a big unburying of a vault they had saved for 50 years. In there was a brand new car complete with gas in case gasoline was obsolete in 2000. The gas was stale and unusable. The car was completely rusted the point where it couldn't be restored. The only answer that you can be confident of storing something is if someone every few years personally looks at it and verifies it is still in good shape and if not repairs it. Archaeologists can learn a lot from garbage and trash that was buried with no attempt to save it. However, archaeologists are also very aware of the limitations of what they can get. There is a lot they know they don't know because, well, this would not have been saved or been preserved.
