Not sure I agree with that.  The md checks he's been doing will cause a 
read of all data regions of the relevant partition and if the disk is 
throwing errors, those sectors should be marked probational.  Then, if a 
subsequent repair ends up remapping them, those sectors will show up as 
remapped.

The grep will show both probational and remapped sector counts for each 
drive.

BTW, the cmd should also include an echo so it's easy to tell which 
drive is being reported:

for di in a b c d e f g; do echo $di; smartctl -a /dev/sd$di | grep -i 
_sect; done
