SUMMARY:
I pose the following question in the subject, as over the years running
smartd and having failed disks, I have always first been alerted of bad
sectors and such through dmesg or logcheck.  Even with a bad disk I
currently have, smartd does not pickup any errors, except those with the
kernel writes to syslog.

What do

	smartctl -H
	smartctl --all

tell you?
