thanks for the advice dswv42 … i understand your concerns and you should know you’re not dealing with the typical ‘genius’ as you referred … i’m fairly cautious about how i use terminal and ssh to issue commands and make sure something i’m typing is exactly what i intend it. i am not an expert though so i do read up on what i’m doing before i do it.
here is the output of my physical disks:

the output looks ok to me, i want to read up more about SMART data and what the raw values mean to better understand the output.
