The following SMART attributes appear in the documentation for HDAT2:

ID Description
-----------------------------
170 (AAh) Reserved Block Count
171 (ABh) Program Fail Count
172 (ACh) Erase Fail Count
173 (ADh) Wear Leveling Count
174 (AEh) Unexpected Power Loss

I expect that they are SSD attributes only.

I suspect that the above attributes were introduced as a group by one
SSD manufacturer.

The list of attributes also includes the following:

99 (63h) Average FHC (Maxtor)
100 (64h) Erase/Program cycles (Maxtor) ... ???
101 (65h) Maximum FHC (Maxtor)

FHC = flying height control ???

Other interesting attributes are ...

241 (F1h) Total LBA Write (IBM)
242 (F2h) Total LBA Read (IBM)

I've found quite a few more SSD & CompactFlash SMART attributes, with

Interesting!

Lets see what mine (OCZ Core 32GB) supports:

9 with a raw value of 0, i.e. meaningless
12 with a raw value of 3950, that does not seem to change, again
meaningless
194 Temperature, works
229, 232, 233, 234, 235: Still unknown

A bit disapointing. Not your fault of course.

On 19 Jan 2009 21:02:28 GMT your SMART stats were:

9 Power_On_Hours 0x0032 100 100 000 - 0

12 Power_Cycle_Count 0x0032 100 100 000 - 241

194 Temperature_Celsius 0x0007 032 100 000 - 0

229 Unknown_Attribute 0x0002 100 000 000 - 259986015180268

232 Unknown_Attribute 0x0002 100 048 000 - 9028846498104

233 Unknown_Attribute 0x0002 100 000 000 - 0

234 Unknown_Attribute 0x0002 100 000 000 - 592722311424

235 Unknown_Attribute 0x0002 100 000 000 - 187423

Was that a different device?
