Why do old hard drives/HHDs eventually have their discs stop spinning?

Question

[Context if needed on them](https://en.wikipedia.org/wiki/Hard_disk_drive), A few old ones I own stopped working due to their spin, and I’m curious to see why it happened to both of them

Answer 1

Same reason a car stops working, wear and tear. Anything with mechanical movement will eventually wear out. That’s why SSD’s are much more reliable, they are solid state and don’t wear out.
