The ball bearings have lubricant that can shift over time due to gravity. And the metal parts might weld to each other over time if they are not moved.

- cbg0 7y agoHow likely are these things to actually happen?
- sp332 7y agoI think the welding takes more than a year. The lubricant settling probably depends on the quality of the drive and the ambient temperature. And I guess the ball bearings would be pretty tolerant (since you only have to move them a little to get the lubricant on them again), it's more likely that the heads would stick. https://en.wikipedia.org/wiki/Stiction#Hard_disk_drives https://en.wikipedia.org/wiki/Stiction#Hard_disk_drives
