Kingston ssd wearout not detected

[sthibaul]

Hello,

Some SSD disks unexpectedly failed, and we have noticed this difference between good devices and failing devices:

good:

169 Remaining_Lifetime_Perc 0x0000   093   093   000    Old_age   Offline      -       93

bad:

169 Remaining_Lifetime_Perc 0x0000   000   000   000    Old_age   Offline      -       0

So this probably needs to be added to a list of values to check.

Similarity to #86 . It seems that attribute 169 (Remaining_Lifetime_Perc) is a decreasing counter and needs to be handled differently than other attributes (including 202 Percent_Lifetime_Remain).

They also have

231 SSD_Life_Left           0x0000   000   000   000    Old_age   Offline      -       0

231 SSD_Life_Left

Is this a decreasing or increasing counter?

It's decreasing as well, that was the output from the old disk
