Problems with spindown

On my T43p (, 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:

# hdparm -C /dev/sda


     drive state is:  standby

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.
