--- Begin Message ---Package: hdparm Severity: serious Tags: jessie sid It is very common that hard disks default to do excessive head parking attempts (click-ripples like every 8 seconds), just to be woken up immediately. To prevent early damage, a save default is: hdparm -B 254, but there seems to be no possible way to configure such a default that works for all disks out of the box. To support a proper default, and actually shipping such a default, I would suggest to support wildcards in hdparm.conf. And ship with a visible default like this: # default to prevent excessive hard disk wear # (head parking, load-cycling) /dev/disk/by-id/ata-* { apm_on_ac = 254 apm_on_battery = 128 } Note 1) There is currently some code in 95hdparm-apm that conditionally applies *hardcoded* apm values (128/254) on battery/ac changes, but *nothing* for booting/udev plugging with proper defaults. Note 2) It makes sense to have some new apm_on_battery and apm_on_ac options (in addition to the current apm option), to avoid disabling quick head parking for mobile battery devices on the move.

We have an udev script which does set options when disks are plugged. And the default options includes -B254: $ (. /lib/hdparm/hdparm-functions; hdparm_options /dev/sda) -B254 So I believe that this bug is fixed in version 9.43-2.
