Hi Rainer,
I can not reproduce this problem on my machine:
lsb_release -c
Codename: jessie
hdparm -V
hdparm v9.43
egrep -v "^$|^#" /etc/hdparm.conf
/dev/sdc {
apm = 64
acoustic_management = 250
}
/dev/sdd {
apm = 128
}
/dev/sdf {
apm = 48
}
for disk in sdc sdd sdf; do echo $disk; hdparm -I /dev/$disk | egrep
"level:|acoustic"; done
sdc
Advanced power management level: 64
Recommended acoustic management value: 254, current value: 250
sdd
Advanced power management level: disabled
Recommended acoustic management value: 128, current value: 128
sdf
Advanced power management level: 48
Recommended acoustic management value: 208, current value: 0
The values are set after reboot or after init script restart.
Best,
Alex
