this morning I upgraded 11.0 to 11.1 on my Lenovo 3000 N200. Now I keep hearing a click-like noise from my hard disk at least every few minutes, sometimes even more frequently.
I think this noise comes from the read/write heads getting parked. I heard it in 11.0 too, but not that often. It concerns me a bit because I heard it was bad for the drive if the heads are constantly parked.
Is there any way to adjust the time after that happens?
Seems to me, it is the old known problem of Linux with SATA HDD drives. Try to tune the “power saving” via Laptop Mode Tool (see /etc/laptop-mode/laptop-mode.conf).
Also, check the /etc/sysconfig/powersave.
I see that the correct power management setting for my HDDs are set only if I login via the kdm.
If I login on a text console only the second hdd is correctly set (the one on which the root partition is). The first one is ignored.
I have the same problem, however in my case the disk is clicking after each and every operation, in that it parks the head. Using smartd I tracked the number of load cycles and sure enough, these increase after each click.
I’ve written a script that sets hdparm -B 254 /dev/sda upon boot, and as hooks to thawing and waking up from hibernation and suspend, respectively.
However, something else in the system changes the hdparm settings! After a while, I guess after the screen saver, the values return to defaults and it starts clicking again. Also, the wake and thaw hooks do not seem to work always.
Can anyone say what other parts of the system could be touching hdparm settings?
