Same firmware as Joe's, too, though his ad1 was a bit later (3.AAG or H?)

I noticed Joe's Temp readings look similarly borked too - attribute 190
is likely something else, despite same flag value as 194, which then
shows clearly wrong values for min/max, though raw temp is reasonable:
190 Temperature_Celsius 0x0022 065 056 045 Old_age Always - 605749283
194 Temperature_Celsius 0x0022 035 044 000 Old_age Always - 35 (Lifetime Min/Max 0/15)
.. which only goes to show, as I've seen with other attributes on other
drive brands, that smartctl's database isn't necessarily reliable over
all versions / revisions of a given drive. Add salt to taste ..
Cheers, Ian
