Understanding 'not capable of SMART self-check' and 'failed to read
SMART Attribute Data' from smartd?
I can execute the -H check which reports PASSED for the drive in
question. I can execute the -P show variant of the smartctl command
sequence. I can execute the (detail) information variant of the
smartctl command sequence. No errors or alerts presented by any of the
these commands, so I don't understand what smartd is reporting, when the
results from smartctl show no issues, apparently? I am new to
smartmontools... so am I missing something (obvious) here?

From smartd.conf... Is my understanding that per the documentation,
ANY THING after the DEVICESAN line is IGNORED, this per the
documentation in the default smartd.conf file.
