What are some strange stories that the SMART of used drives has told you?

I'm looking at this one 4TB drive I got recently that has a manufacturing date in 2013, total written amount of 12 TB, restart count ~500, but total power-on only around 1,000h. I was wondering what happened there, why a restart every 2h, and was it really used intensely for only 1 month in 10 years...

What are some weird ones you've seen?

I'm assuming SMART attributes can't be set selectively can they? AFAIK SMART reset is an all-or-nothing deal that wipes the whole thing.

My 970 EVO 500G that I bought used with 2h of power on time, had about 400 power cycles.
Not really SMART related, but I'm currently using an 1TB Sandisk Extreme Pro that identifies as WD black SN750. Same hardware, but IDK how (and why) someone flashed the wd firmware on it.

I have a few 100gb SLC Hgst SAS SSDs that all have multiple petabytes written on them. Apparently the worst one only has 96% life remaining and only ~37 power on hours.
Came out of an EMC VNX or some other EMC product.

I have a drive that was decomissioned, presumably, due to 2 errors during long smart tests (within 2k hours, at roughly 30k). Other than that it has perfect SMART parameters, surface tests without issue, and has been running for a year 24/7 no problem now. Other than excessive vibration or a power issue I have no idea what could have caused that.
- Wear and tear?
  
  I'd expect that to be permanent.
