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
