I have now downloaded and run Seagate's tools and it does show a does 
show a disk error.  Since it stops on the first error I do not know if 
this is an isolated error, or a more systematic problem.

Automatic Write Reallocation Enable (AWRE) is on by default, but 
Automatic Read Reallocation Enable (ARRE) is off.  If I set ARRE on and 
then run the long test (which reads all sectors sequentially), will that 
reallocate any bad sectors and mark them as such?  Is this a safe thing 
to do?
