What does “effective” (ages 2 to 6) mean here? What do I want to show to a kid when I’m angry? That I resort to violence? Do people really think that kids don’t know that parents can be angry?
I cannot imagine one single reason to lose an argument to a 6 year-old kid, stop talking and just hit them.
You’re just a bad parent, if you do that. That’s all.
There is nothing to refurbish in drives. They are just second hand devices. You can check if they are fine pretty easy and you need to take a look at the age (power on hours). I replace drives at 50k-60k hours, no matter if they are fine.
