Spin down external HDD ?

1st Official Post

    Hi, I've attached a Seagate Backup Plus external HDD to my Raspberry Pi running LibreELEC. Everything works just fine. This drive is a little more active than the previous one, a WD My Book. And what I was wondering now, is it possible to spin down this drive after being idle for let's say one hour or so? Is this possible, does it bring anything? Extented life? Less energy usage? Or should I just leave things as they are? Thx, Zach

    Hi, searched related to hdparm and then issued:

    LibreELEC:~ # hdparm -S 128 /dev/mmcblk0p2

    /dev/mmcblk0p2:

    setting standby to 128 (10 minutes + 40 seconds)

    HDIO_DRIVE_CMD(setidle) failed: Invalid argument

    Afraid the last message (invalid argument) predicts this won't just work.

    Any help? Thx, Zach

    LibreELEC:/dev # hdparm -S 128 /dev/sda2

    /dev/sda2:

    setting standby to 128 (10 minutes + 40 seconds)

    LibreELEC:/dev #

    Tried again with /dev/sda2...seems to work now. Let me check...

    Thx! Maybe i'll recall this message in 10 minutes + 27 seconds :)
