One of my computers has an SSD (model ADATA SP600NS34) which doesn't report its used life as a SMART attribute. It does, however, report it in the "General Purpose Log".

$ smartctl -l ssd /dev/sda

Supported tables can be listed with smartctl -l devstat,0 and each supported table can be retrieved using smartctl -l devstat,<page>. -l ssd is equivalent to -l devstat,7. The SMART attributes for the aforementioned SSD:

check_smart could retrieve the general purpose log pages and treat them similar to the SMART attributes.

Interesting case. Just out of curiousity, what does smartctl -a /dev/sda show on that SSD? It might also be a missing device recognition in smartmontools' smartctl to show the attributes directly.

According to https://www.smartmontools.org/browser/trunk/smartmontools/drivedb.h?rev=5047#L1683 the ADATA SP600 devics should be recognizable by smartcl:

{ "JMicron based SSDs", // JMicron JMF61x, JMF66x, JMF670
--
"ADATA S596 Turbo\|"  // tested with ADATA S596 Turbo 256GB SATA SSD (JMicron JMF616)
"ADATA SP600\|"  // tested with ADATA SP600/2.4 (JMicron JMF661)
"ADATA SP310\|"  // Premier Pro SP310 mSATA, JMF667, tested with ADATA SP310/3.04
"ADATA SX930\|"  // tested with ADATA SX930/6.8SE
...

According to the smartmontools changelog, this model was already added in March 2014.

I'm including the output below. The machine in question runs Debian Buster.

ADATA SP600 devics should be recognizable by smartc[t]l: […]

The regular expression is for ADATA SP600 (among others) while the device uses ADATA SP600NS34. The structure description in drivedb.h says that the "regular expressions for drive model and firmware must match the full string". So this is definitely a problem, but not the cause: none of the attributes seems to be for the lifetime percentage.

The SSD was recognized after that, but as described in comment #52 (comment) the model in question doesn't report its lifetime as a plain SMART value. There is a value in the General Purpose Log.
