The question is whether these values have been like this from the start.
I think it is a little bit unusual for the drive to have a threshold of
zero for 195-197. And it makes me suspicious that not even attributes 9
and 12 are counted properly.

I think both of these values don't matter to SSDs at all. They shouldn't
care about shocks and don't have a head which could "fly high".
Conclusion: While the warnings indicate a broken disk, they look a bit
fishy to me. It looks the manufacturer used standard firmware from a
regular hard drive and didn't adapt it to SSDs properly. For comparison,
here are *all* values my Intel X25m reports via SMART:
ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE
3 Spin_Up_Time 0x0000 100 000 000 Old_age Offline - 0
4 Start_Stop_Count 0x0000 100 000 000 Old_age Offline - 0
5 Reallocated_Sector_Ct 0x0002 100 100 000 Old_age Always - 0
9 Power_On_Hours 0x0002 100 100 000 Old_age Always - 1703
12 Power_Cycle_Count 0x0002 100 100 000 Old_age Always - 509
192 Power-Off_Retract_Count 0x0002 100 100 000 Old_age Always - 445
232 Available_Reservd_Space 0x0003 100 100 010 Pre-fail Always - 0
233 Media_Wearout_Indicator 0x0002 097 097 000 Old_age Always - 0
225 Load_Cycle_Count 0x0000 200 200 000 Old_age Offline - 45681
226 Load-in_Time 0x0002 255 000 000 Old_age Always - 0
227 Torq-amp_Count 0x0002 000 000 000 Old_age Always - 0
228 Power-off_Retract_Count 0x0002 000 000 000 Old_age Always - 0
I think I would try finding and using the manufacturer's diagnostic tool
(which might be a pain without Windows) and see what it reports. I would
expect it to report no problems.
