If you've ever held the power button to shut your PC down, you've done an "unsafe shutdown," and chances are that your SSD wasn't too happy about it. The event was probably logged, adding up to your error count.

This is a PSA: Please stop abusing your SSD. Mistreating it is easier to do than it might seem. We all do it to some extent, but if you do it too much, it'll eventually backfire.
