In what way has the SMART read failed?

Mis-parse :) It was my _attempts_ to read SMART that failed.
Specifically, I was able to read a table of numbers from the drive, but
none of the numbers looked particularly useful or likely to be a "time
to live" number. Similar to traditional drives, where you get this table
of numbers that are either zero or random, that you look at saying
"Huh?", all of which are flagged as "failing". Perhaps I'm using the
wrong SMART groking tools ?
I run:
sudo smartctl -a /dev/sda
And amongst the usual values, I also get:
232 Available_Reservd_Space 0x0002 100 048 000 Old_age Always
- 9011683733561
233 Media_Wearout_Indicator 0x0002 100 000 000 Old_age Always
- 0
The media wearout indicator is the useful one.
Plus some unknown attributes:
229 Unknown_Attribute 0x0002 100 000 000 Old_age Always
- 21941823264152
234 Unknown_Attribute 0x0002 100 000 000 Old_age Always
- 953583437830
235 Unknown_Attribute 0x0002 100 000 000 Old_age Always
- 1476591679
I found some suggested definitions for those attributes, but they didn't
seem to match up with my values once I decoded them, so mine must be
proprietary.
