SATA drive state sensing problem.

New page

== Problems with spindown ==

On my T43p (2.6.15.3), 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:

{{cmdroot|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:

{{cmdroot|hdparm -C /dev/sda}}

yields:
/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.
