On some drives, yes, but not all drives.  His is a Seagate drive --
Seagate uses some of the bits in the "raw data" section for some sort of
internal use by the drive firmware.  So as they may appear very high in
value, the drive appears to function normally, and the actual "adjusted
SMART value" (the field under VALUE) doesn't fluxuate.

I have Seagate drives all over the place which exhibit identical stats
to the above.  I've included some for comparison below; each listed is
on a different system.  Look at attribute 190 (Temperature Celcius) for
an example; I don't think any drive can reach 773849124C, for example.
Or, well, I sure hope not.  :-)  I believe in the case of attrib. 190,
that's why they present a human-readable value in attribute 194.
