Magnetic platters absolutely do break down from sitting around. Bearings and other mechanics can also go bad. For those things, a professional recovery operation could still get the data if you're willing to pay, but the drive itself should be thrown out.

Edit: keep in mind that with bit rot, the drive may superficially function just fine. Your data may even be 99% correct. That 1%, however, could cause unrecoverable problems, such as videos that glitch in the middle.

That's why you use multiple drives with bitrot protection. Modern SSDs and HDDs have protections against bitrot built in, including internal checksums.

If you are running your hard drives once in a while, then bearing failure isn't really a concern. You probably should be doing that anyway to refresh the data and make sure it doesn't degrade. Regardless people have had 10 year old drives of older spin up first time. It's not likely you are going to have a mechanical issue on multiple drives anyway.

If you refresh an SSD once every couple of years it will last decades.

You keep doing this thing where you presume I don't know about some issue. Rather I know about these things, but they have fairly easy mitigations or are already solved.

Maybe because you way overestimate the reliability of old drives. Yes, 10 year old drives can work. Doesn't mean you should trust them with anything other than getting the data off of it.
