I have 2 Iron Wolf drives that are aggressively spinning down. I have tried turning on the standby feature in "drive settings". I have also run sudo hdparm -I /dev/sdc | grep level and get no output. So I run sudo hdparm -S 120 /dev/sdc and get

/dev/sdc:
 setting standby to 120 (10 minutes)

But nothing. I still see the drive in the "disks" utility with "zzz" immediately after copying a file over to the drive.

Can anyone help?

Thanks, Chris

EDIT: running 18.04

  • you need to specify the version and type of ubuntu you're using. add the tag at least. – tatsu Jun 21 '19 at 14:33
  • are you sure it has spun down? Could you recheck with smartctl -i -n standby /dev/sdX if Power mode is: Active, Idle, or Standby - smartctl is part of package smartmontools – AlexOnLinux Jun 21 '19 at 16:38
  • Hi. Here is the output ```sudo smartctl -i -n standby /dev/sdc smartctl 6.6 2016-05-31 r4324 [x86_64-linux-4.18.0-22-generic] (local build) Copyright (C) 2002-16, Bruce Allen, Christian Franke, www.smartmontools.org

    Device is in STANDBY mode, exit(2)``` SMART also reports high read error rates on both drives. Perhaps worth mentioning is that they are connected to sata 2.0 ports.

Your hdparm command doesn't work because you probably also have the udisks2 daemon running which spins down the disk on its own schedule (and/or overwrites your settings).

Thus, you can either stop/disable/mask that daemon, e.g. to just temporarily stop it:

systemctl stop udisks2.service

Or change the StandbyTimeout= udisk2 setting for your disk.
