I second that. In fact I used to do timed surface runs to find
drives with problems in a cluster environment before moving
to smart. This was pretty reliable. Defective drives take
significantly longer to read data than others (If they do not
fail at it directly).

Another piece of software that will give you a SMART readout is
Speedfan, even if you use it occasionally only for that purpose, not
to control/monitor fans. It is free.

Yeah, it does display SMART values, but does not make any sort of
analysis of that data.

The purported 'analysis' is completely useless.

It show OK with even the most obvious problems.

A good example is the reallocated sector count
with your second drive, thats much too high.

That's not the kind of analysis I'm talking about. It needs to be able
to see all of those numbers and come up with an overall health report.
Hard Disk Sentinel can do that.
