They exist, but they’re crude. Indoor farms tend to be labor intensive, meaning they have a lot of incentive to automate, but nobody has a really good system yet.
Knowing when a tomato is ripe and how to pick it off the plant is one of the better uses for AI image recognition and robotics, IMO.
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.
