Hi, thank you for SMS!)

How can I set SMS to stop automatically my HDD rotation after preset period of unused time? Command line mode, without KDE.

Using hdparm.
60 = 5 minutes
120 = 10 minutes
180 = 15 minutes

I tried:

root@slackware:/# hdparam
sh: hdparam: command not found

What to do?
Sorry. I'm not good in linux Smile

It's hdparm not hdparam Wink

I have /dev/sda1 /dev/sda2 /dev/sda3 as my parts of single HDD disk,
this command (hdparm) doesn't stop rotation for some reason.
Tried
# hdparm -S2 /dev/sda1
# hdparm -S2 /dev/sda2
# hdparm -S2 /dev/sda3
and also
# hdparm -S2 /dev/sda
-no effect even after an hour.

I guess some SMS daemon may be frequently accessing my HDD and hdparm takes no effect?

Well -S2 (10sec) might be a little to quick for an HDD to respond, try something above 30sec.
The command is passed to disk and not to partitions, so you have to pass it to
/dev/sda.
Now if the disk has no activity for the time you set e.g. 2 minutes or 30 seconds it will spin down disk, but since your /dev/sda is your OS disk, might not spin down at all, depending on the services you are running.

If you have a second disk, you can try it there...
