The VALUE and WORST columns contain normalised values for all of the 
attributes, between 0 and 255.

The VALUE part is the current normalised rate, over time. The WORST part 
is the normalised value of the worst rate there has been in the history 
of the device.

The THRESH value is the point at which the device is likely to fail.
