Running hdparm w/o waking up hard disk

linux-howto

http://forums.fedoraforum.org – I send my hdd to sleep with /sbin/hdparm -S 241 /dev/sd[ab] every day at 8:30 pm. If there's no activity for 30 minutes the drive will enter standby. At 06:00 am I want to change the 30 minutes to 4 hours. But when I enter /sbin/hdparm -S 248 /dev/sd[ab] in the morning both drives spin up. Is is possible to run /sbin/hdparm -S xxx /dev/sd[ab] without waking up a hard disk? Or to detect whether the hard disks are already in standby? (HowTos)

I haven't seen anything like this before.  Upon rebooting:% hdparm /sbin/hdparm: /sbin/hdparm: cannot execute binary fileThe permissions are fine:ls -l /sbin/hdparm -rwxr-xr-x 1 root root 105440 Nov 3 02:47 /sbin/hdparmIf I capture its md5sum:% md5sum /sbin/hdparm 321ff7b32611a82c719ec7f7a7b5a67c /sbin/hdparmNow, I reinstall and everything is fine; note the DIFFERENT md5sum:% sudo pa

I want to spin down some hard-disks when they are idle. So I used hdparm package. In the /etc/hdparm.conf I added following lines:

command_line { hdparm -Ss 241 /dev/sda }

My intention was to spin down hard disk after 30 minutes of idle time. However, my problem is, how I know for sure whether hard disk has spun down (assuming that it had exceed idle time of 30 minutes)??

Any ideas? Tips??

Who's been using my harddrive? 3 years 30 weeks ago

Hi! I've recently upgraded from fedora 9 to 11. One issue I am now facing is, my hard drive no longer goes to sleep anymore. I have 3 hard disks, 2 of them are barely used. In Fedora 9 I usually do: hdparm -S 241 /dev/sda. Then the drive would go to sleep after idling for a while.

But now, when I issue a command: hdparm -y /dev/sda

Setting SATA HDD spindown time 32 weeks 3 days ago

I am able to spindown my SATA HDDs by using

sudo hdparm -y /dev/sdc

The state shown by

sudo hdparm -C /dev/sdc

changes from active/idle to standby (and I can hear the HDD spin down).

However, using

sudo hdparm -S5 /dev/sdc

doesn't spin down the drive after 5*5 = 25secs.

Some additional information:

AHCI is enabled. I am using Western Digital Green drives. APM_level = not supported Fil

Hello everybody!

When on battery, my laptop hard drive makes a tock tock every couple of seconds. Now if you think "this one is easy, hdparm...", wait a second, it gets trickier.

First of all: this is not a hardware issue, I have no problem under Windows 7 (I dual boot) and when the AC cable is plugged in.

Some of these new hard drives call this clicking a "power-saving" feature, especially if it is a laptop size drive. The click is from the hard drive parking it's head. Try opening your console and running "hdparm -B 254 /dev/sda" as root. Of course change /dev/sda to whatever your hard drive is if it is different. Then see if the clicking stops.

I've tried sudo hdparm -B 254I've reconfiguring GUI power manger a few different ways, and I even reinstalled! But it still won't stop spinning. As far as I know, my swap isn't even activated and it's definitely not being used.

I'm currently configuring a new home server, and I am trying to get the disks to spin down after one hour. But they do not spin down.

Setup

I have my entire system on an ssd: /dev/sda. I have three hdds in the system: /dev/sdb, /dev/sdc and /dev/sdd.

Hi all,

I'm working on a project to spin-down all of my hard drives (except the boot disk) when they aren't accessed. I'm running a fresh install of 9.10 and I have the following set of drives:

/dev/sda1 -- boot /dev/sdb1 -- HDS 500GB member of md0 raid 0 /dev/sdc1 -- SEA 500GB member of md0 raid 0
