Re: No value for THRESH column

Hmm, this is a little more difficult.

As you should be noted, this is a internet gateway running pfSense. I was
trying to collect SMART data to Zabbix, since it is in a production
environment. I need to schedule this procedure out of business hours.

But your assumption about a driver issue does make sense, since I really
don't know how well supported are FreeBSD drivers. I'll try to use a Live
Distro running Linux to check what happens.
