worrying message from smartd


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

Powered_Up_Time is measured from power on, and printed as

SMART Self-test log structure revision number 1
No self-tests have been logged. [To run self-tests, use: smartctl -t]


SMART Selective self-test log data structure revision number 1
SPAN MIN_LBA MAX_LBA CURRENT_TEST_STATUS
1 0 0 Not_testing
2 0 0 Not_testing
3 0 0 Not_testing
4 0 0 Not_testing
5 0 0 Not_testing
Selective self-test flags (0x0):
After scanning selected spans, do NOT read-scan remainder of disk.
If Selective self-test is pending on power-up, resume after 0 minute delay.
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.
