Huh?

SMART doesn't store its info in the user accessible part of the disk, 
afaik. Only a IDE low-level format might erase the SMART information.

Of course, writing to the damaged area may cause the error go away 
because the sectors are remapped, but doesn't SMART have an error log, 
so that the tech can still see that there were problems?

cheers
