How smart is S.M.A.R.T.?

[Wayne Davis]

The info shows you have not lost anything BUT you do have some bad spots 
on the drive which have been de-allocated.

IF you have the time, you can use "Spinrite" to re-cert a drive. I did 
this once with a drive that was "JUNK" and given to me from the company 
I worked for.  It took a week on Spinrite, but after that did not fail.  
I took it out of service due to it's size years later.  (SMALL) Spinrite 
writes every possible combination of data BITS to every writable area, 
locks out bad sectors and more.  IT DOES WORK.  I've used it several 
times over the years.
