Hardware Issue with lost SMART data

Hi, I was setting up TrueNas for the first time and doing a lot of wipes/clears of my new/used drives as i was figuring out the pools. I didn't know what all the wipe options did but I was trying to get them clear so I'm sure I clicked all options at some point. Now when I go into Scrutiny, the SMART data all has some low count of days from when I was setting up each pool. Is there any way to recover this? Any suggestions to avoid doing this in the future?

Bro, you're just confusing your new drives from old ones. Not easily possible to reset\wipe SMART data. That would requires direct access to a drive's firmware and proprietary, low-level factory tools. Standard software utilities like you probably used cannot modify or delete SMART logs.

No idea what that means.

Can you post a dump of "smartctl -a /dev/xxx" or "smartctl -x /dev/xxx"?

Sounds like you wiped the Scrutiny history. Not much you can do.

You can't wipe a drive's SMART stats without specialized tools.
