Problems with spindown
On my T43p (2.6.15.5), these tools plain don't work for me -- the daemon refuses to spin down my hdd despite the most aggressive values put in the laptop-mode.conf file.
So far trying to debug the problem:
# hdparm -y /dev/sda
works perfectly -> drive will spindown properly. I obtained the much simpler spindown shell script, and looking into this issue noticed that the command:
# hdparm -C /dev/sda
always returns:
/dev/sda:
drive state is: standby
regardless of the current state of the drive, and the script never goes further (thinks the drive is in standby, when it is clearly spinning...)
Of note, I do not have the IDE driver in my kernel, only using the SATA - ATA_PIIX compiled in. Perhaps I need to include the IDE module to sense the drive state correctly? This seems a bit bizarre, as everything else works well.
Update - compiling IDE drivers into the kernel does nothing to change the output - drive is always listed as "standby" no matter what state it actually is in. Of note, setting the spindown parameter (e.g. 10 seconds with:
# hdparm -S 2 /dev/sda
works correctly...
