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.
