I recently installed smartd. Recently I got this message in my syslog:

Here's the output from smartctl -H

Any suggestions? "smartctl" gave a similar message about 2 weeks ago and my HD hasn't died yet(!). I'm afraid I'm new to smartd and don't understand a lot of the messages.

[EDIT]
I've just found some entries on google that suggest that the Raw_Read_Error_Rate message is a known "nuisance" message - eg. http://wiki.clug.org.za/wiki/How_do_...eading_them%3F
Can somebody confirm this? How can I disable this in smartd.conf?

I've had similar messages and came to a partially similar conclusion as you did.

However 7200rpm drives get rather hot and cooling will probably help.

In my case I modified the case (drill, hacksaw and file job) and installed a fan which blows air through the spaces between the drives. I got a 5 deg C improvement. You might want to be less drastic and buy a drive cooler.
