@synapse1278 I recently bought a used 8tb drive off ebay for $45. Manufacturing date on the drive was 2016, but Power_On_Hours was 4 (four!). I asked the seller if they reset SMART data; his response:
"We do not reset power on hours, as we could get in a ton of trouble listing used drives as new bulk etc after altering the power on hours. This one likely was used in/for testing an array etc. "
So I'm pretty pleased with that..
@semperverus @possiblylinux127 No, this other person has a working 'e' key on their keyboard.
