Yes, and that 36 should be watched, any increase means that drive is on its way out. Usually quicker than next week. I'd replace it just for S&G, but today I'd replace it with an SSD, not spinning rust. Among other things the SSD is around 4x faster. I just had a new 2t spinning rust go belly up in the night, so I now boot from a 500G SSD, and put in 4 1T SSD's in a raid10 for /home.
