As you can see, there are lots of unknown attributes:

165 Unknown_Attribute 0x0032 100 100 --- Old_age Always - 196609
166 Unknown_Attribute 0x0032 100 100 --- Old_age Always - 0
167 Unknown_Attribute 0x0032 100 100 --- Old_age Always - 23
168 Unknown_Attribute 0x0032 100 100 --- Old_age Always - 1
169 Unknown_Attribute 0x0032 100 100 --- Old_age Always - 143
170 Unknown_Attribute 0x0032 100 100 --- Old_age Always - 0
171 Unknown_Attribute 0x0032 100 100 --- Old_age Always - 0
172 Unknown_Attribute 0x0032 100 100 --- Old_age Always - 0
173 Unknown_Attribute 0x0032 100 100 --- Old_age Always - 0
174 Unknown_Attribute 0x0032 100 100 --- Old_age Always - 0

Is there any way to figure out what do those attributes mean?

Here's what I got from this page

​http://forums.sandisk.com/t5/SanDisk-Extreme-II-SSD-Legacy/Extreme-II-SMART-parameter-specification-sheet/td-p/321108

for some of those unknown attributes:

5 / 05 - Retired Block Count [1 block = 4 MB]
9 / 09 - Power On Hours

12 / 0C - Device Power Cycle Count

166 / A6 - Min W/E Cycle
167 / A7 - Min Bad Block/Die
168 / A8 - Maximum Erase Cycle
169 / A9 - Total Bad Block

171 / AB - Program Fail Count
172 / AC - Erase Fail Count
173 / AD - Average Erase Cycle
174 / AE - Unexpected Power Loss Count
187 / BB - Reported Uncorrectable Errors
194 / C2 - Current Temperature
212 / D4 - SATA PHY Error

230 / E6 - Percentage Total P/E Count XX.YY
232 / E8 - Spare Blocks Remaining [%]
233 / E9 - Total GB Written to NAND
241 / F1 - Total GB Written
242 / F2 - Total GB Read

There are still 165, 243 and 244 that are missing. They do come from SanDisk SSD Dashboard support software, however, I've only got an linux box and mac OS box.. will not be able to install their windows-only software.
