The issue happens when the disk transits between operational states and  
non-operational states.

If you are torrenting, then chances are the disk is always in operational  
states, so you don’t see the issue.

>   I have a Razer Blade Stealth 2016. The first Ubuntu I installed was Ubuntu 17.04, which gave me this error after 2 weeks of usage. After that, I installed 16.04 and used it for MONTHS without any problems, until it produced the same error this week. I think it has to do with the ubuntu updates, because I did one recently and one today, just before this problem. Could be a coincidence though.
