Hi, I have two hard drive connected to my Raspberry Pi 3. One is SATA III, one is IDE, all with relative HDD box via USB.
This is the situation:
root@DietPi:~# hdparm -C /dev/sda
/dev/sda:
drive state is: unknown
root@DietPi:~# hdparm -C /dev/sdb
/dev/sdb:
drive state is: standby
root@DietPi:~#
/dev/sda ==> IDE drive
/dev/sdb ==> SATA drive
What I have to do to disable ALL spin down?
Thank you!
IDE look unsupported
SATA looks fine
You’ll need to edit /etc/hdparm.conf, and configure section /dev/sda:
#DietPi external USB drive. Power management settings.
/dev/sda {
spindown_time = 0 # = disabled
apm = 254
}
Also add one for sdb

Hi, for /dev/sda (IDE disk) that lines already exists in hdparm.conf .
I created that lines for /dev/sdb (SATA disk) but the results is:
root@DietPi:~# hdparm -C /dev/sdb
/dev/sdb:
drive state is: standby
Is that ok?
Thank you!
That disk continuous to spin down. Sometimes I found it unmounted(only SATA drive: /dev/sdb)
Its possible the drive has its own power management, and, HDParam does struggle with some USB > SATA converters which are not compliant (especially china town).
Check the available supported features available to HDparm:
