I didn't have smartctl but have installed it, and run it, and it gives 
reaocated_sector_ct value as 100 and worst as 100 with "threash" at 
20.   It has no errors logged.

At first I thought that the value was bad, but I have been reading up on 
what it means, and this seems to be good.  (though I am not sure)  I was 
wondering if the results were meaningless if smartctl was not already 
installed.  But the impression I get is that the data is on the disc and 
this is a utility to retrieve the data.  (Is that right?)

I am running the self tests now to see what that comes up with.
