acpi hdd code

[curtis e. bear]

can someone help me figure out some code to put in /etc/acpi so that the hard drive powers down after 30 minutes?

[arthur]

install this program called hdparm, and issue the command as root:

 

root@localhost # hdparm -S 241 /dev/hda

 

that gives a spindown timeout of 30 minutes, if you want to learn about the timing, type "man hdparm". HTH

i didn't get an error entering the command, but it doesn't appear that the hard drive spins down...

[arthur]

try 'hdparm /dev/hda' and it should print a bunch of info to see if it's installed properly.

'hdparm -y /dev/hda' will put your hd in standby and 'hdparm -Y /dev/hda' will put it to sleep.

 

hdparm -S 241 /dev/hda should have printed something like "setting spindown timeout to 30 minutes"

 

to make the changes permanent, you must go into MCC and configure hdparm to start every boot, and put "hda_args = "-S 241"" in /etc/conf.d/hdparm.

at least, that's what i would do in gentoo, sorry, i don't have mandrake so about the MCC stuff... :unsure:

Still doesn't work. I think that it isn't workign because the hard drive keeps being written to, even when it is just sitting there. It's not alot, but it prevents it from starting to spin down.
