I just rebooted my machine after months and had a window pop up telling me one
of my disks had a SMART error reported.  It says DISK HAS MANY BAD SECTORS, and reports the reallocated sector count as follows:

Normalized: 191
Worst:      191
Threshold:  140
Value:       72 sectors

After going to the disk manufacturer and reading up on SMART, it looks to me
like normalized values are better going up and worse going down.  So by that
account, 191 is not perfect but is still reasonable since it is above 140.

As far as I can tell, the drive manufacturer thinks the drive is still good.
That suggests that the utility may be complaining because the raw value is
below the threshold rather than using the normalized one?
